G-code/ru

This page tries to describe the flavour of G-codes that the RepRap firmwares use and how they work. The main target is additive fabrication using FFF processes. Codes for print head movements follow the NIST RS274NGC G-code standard, so RepRap firmwares are quite usable for CNC milling and similar applications as well. См. также Wikipedia's G-code article.

Существует несколько различных способов подготовки G-кода для принтера. Один из способов заключается в использовании программы слайсинга, например Slic3r, Skeinforge или Cura. Эти программы импортируют модель САПР, разрезают ее по слоям и выводят G-код, требуемый для печати каждого слоя. Slicers are the easiest way to go from a 3D model to a printed part, however the user sacrifices some flexibility when using them. Another option for GCode generation is to use a lower level library like mecode. Libraries like mecode give you precise control over the tool path, and thus are useful if you have a complex print that is not suitable for naive slicing. Последний вариант-просто написать G-код самостоятельно. Это может быть лучшим выбором, если необходимо выполнить несколько тестовых линий при калибровке принтера.

As many different firmwares exist and their developers tend to implement new features without discussing strategies or looking what others did before them, a lot of different sub-flavours for the 3D-Printer specific codes developed over the years. Эта страница является главной страницей RepRap. Nowhere in here should the same code be used for two different things; there are always more numbers to use... Правило: "добавьте здесь новый код, а затем реализуйте его".

Unfortunately human nature being what it is, the best procedures aren't always followed, so some multiple uses of the same code exist. The rule which should be followed is that later appearances of a code on this page (later than the original use of a code), are deprecated and should be changed, unless there is a good technical reason (like the general G-Code standard) why a later instance should be preferred. Note that the key date is appearance here, not date of implementation.

Введение

A typical piece of Gcode as sent to a RepRap machine might look like this:

N3 T0*57
N4 G92 E0*67
N5 G28*22
N6 G1 F1500.0*82
N7 G1 X2.0 Y2.0 F3000.0*85
N8 G1 X3.0 Y3.0*33

G-код также может храниться в файлах на SD-картах. Файл, содержащий RepRap G-код, обычно имеет расширение .g , .gco или .gcode . Файлы для BFB/RapMan имеют расширение .bfb . G-код, сохраненный в файле или создаваемый слайсером, может выглядеть следующим образом:

G92 E0
G28
G1 F1500
G1 X2.0 Y2.0 F3000
G1 X3.0 Y3.0

Смысл всех этих символов и цифр (и более) объясняется ниже.

Slicers will (optionally?) add GCode scripts to the beginning and end of their output file to perform specified actions before and/or after a print such as z-probing the build-area, heating/cooling the bed and hotend, performing ooze free "nozzle wipe" startup routine, switching system power on/off, and even "ejecting" parts. More info on the Start GCode routines and End GCode routines pages.

To find out which specific Gcode(s) are implemented in any given firmware, there are little tables attached to the command descriptions, like this one:

Поддержка	FiveD	Teacup	Sprinter	Marlin	Repetier	Smoothie	RepRapFirmware	Machinekit	MakerBot	grbl	Redeem	MK4duo
	Да	automatic	Нет	Частично	Экспериментально	deprecated	???	???	???	???	Да	Частично

Это означает:

{{да}}

G-код полностью поддерживается микропрограммным обеспечением.

{{частично}} или {{экспериментально}}

Существует определенная поддержка G-кода. Often it is required to check out the source code branch for the firmware (usually stored in a different branch) or to flip configuration switches on the mainboard.

automatic

The firmware handles this Gcode automatically, so there's no need to send the command. An example is power supply on/off Gcode (M80/M81) in the Teacup firmware.

{{???}}

It is unknown if the firmware supports this Gcode. You may want to test this yourself before using it in production.

{{нет}}

Микропрограмма не поддерживает этот G-код.

deprecated

The firmware deprecated this Gcode. The firmware author(s) should amend the deprecated Gcode on this page with workarounds (if needed) and the last supported firmware version that will accept this Gcode.

For the technically minded, Gcode line endings are Unix Line Endings (\n), but will accept Windows Line Endings (\r\n), so you should not need to worry about converting between the two, but it is best practice to use Unix Line Endings where possible.

Поля

A RepRap Gcode is a list of fields that are separated by white spaces or line breaks. A field can be interpreted as a command, parameter, or for any other special purpose. It consists of one letter directly followed by a number, or can be only a stand-alone letter (Flag). The letter gives information about the meaning of the field (see the list below in this section). Numbers can be integers (128) or fractional numbers (12.42), depending on context. For example, an X coordinate can take integers (X175) or fractionals (X17.62), but selecting extruder number 2.76 would make no sense. In this description, the numbers in the fields are represented by nnn as a placeholder.

In RepRapFirmware, some parameters can be followed by more than one number, with colon used to separate them. Typically this is used to specify extruder parameters, with one value provided per extruder. If only one value is provided where a value is needed for each extruder, then that value is applied to all extruders.

Буква	Meaning
Gnnn	Стандартная команда G-кода, например перемещение в точку
Mnnn	RepRap-defined command, such as turn on a cooling fan
Tnnn	Выбор инструмента nnn. In RepRap, a tool is typically associated with a nozzle, which may be fed by one or more extruders.
Snnn	Command parameter, such as time in seconds; temperatures; voltage to send to a motor
Pnnn	Command parameter, such as time in milliseconds; proportional (Kp) in PID Tuning
Xnnn	A X coordinate, usually to move to. This can be an Integer or Fractional number.
Ynnn	A Y coordinate, usually to move to. This can be an Integer or Fractional number.
Znnn	A Z coordinate, usually to move to. This can be an Integer or Fractional number.
U,V,W	Additional axis coordinates (RepRapFirmware)
Innn	Parameter - X-offset in arc move; integral (Ki) in PID Tuning
Jnnn	Parameter - Y-offset in arc move
Dnnn	Parameter - used for diameter; derivative (Kd) in PID Tuning
Hnnn	Parameter - used for heater number in PID Tuning
Fnnn	Feedrate in mm per minute. (Speed of print head movement)
Rnnn	Parameter - used for temperatures
Qnnn	Parameter - not currently used
Ennn	Length of extrudate. This is exactly like X, Y and Z, but for the length of filament to consume.
Nnnn	Номер строки. Used to request repeat transmission in the case of communications errors.
*nnn	Контрольная сумма. Используется для проверки ошибки связи.

Case sensitivity

The original NIST GCode standard requires gcode interpreters to be case-insensitive, except for characters in comments. However, not all 3D printer firmwares conform to this and some recognise uppercase command letters and parameters only.

Firmwares that are known to be case-insensitive

Версия RepRapFirmware 1.19 и позже (кроме как в кавычках)

Firmwares that are known to be case-sensitive

Версия RepRapFirmware 1.18 и ранее

Строки в кавычках

В RepRapFirmware некоторые команды поддерживают кавычки при предоставлении имен файлов и других параметров строки. This allows file names, WiFi passwords etc. to contain spaces, semicolons and other characters that would otherwise not be permitted. Double-quote characters are used to delimit the string, and any double-quote character within the string must be repeated.

Unfortunately, many gcode sender programs convert all characters to uppercase and don't provide any means to disable this feature. Therefore, within a quoted-string, the single-quote character is used as a flag to force the following character to lowercase. If you want to include a single quote character in the string, use two single quote characters to represent one single quote character.

Example: to add SSID MYROUTER with password ABCxyz;" 123 to the WiFi network list, use command:

M587 S"MYROUTER" P"ABCxyz;"" 123"

или если не удается отправить символы нижнего регистра:

M587 S"MYROUTER" P"ABC'X'Y'Z;"" 123"

Комментарии

Комментарии G-кода начинаются с точки с запятой и заканчиваются в конце строки:

 N3 T0*57 ; Это комментарий
 N4 G92 E0*67
; Так это
 N5 G28*22

Some firmwares also obey the CNC GCode standard, which is to enclose comments in round brackets. Comments of this form must start and end on the same line:

(Home some axes)
G28 (here come the axes to be homed) X Y

Comments and white space will be ignored by your RepRap Printer. It's better to strip these out on the host computer before sending the Gcode to your printer, as this saves bandwidth.

If present, the line number should be the first field in a line. For G-code stored in files on SD cards the line number is usually omitted.

If checking is supported, the RepRap firmware expects line numbers to increase by 1 each line, and if that doesn't happen it is flagged as an error. But you can reset the count using M110 (see below).

Although supported, usage of N in Machinekit is discouraged as it serves no purpose.

Пример: *71

If present, the checksum should be the last field in a line, but before a comment. For G-code stored in files on SD cards the checksum is usually omitted.

The firmware compares the checksum against a locally-computed value. If they differ, it requests a repeat transmission of the line.

The RepRap firmware checks the line number and the checksum. You can leave both of these out - RepRap will still work, but it won't do checking. You have to have both or neither though. If only one appears, it produces an error.

The checksum "cs" for a GCode string "cmd" (including its line number) is computed by exor-ing the bytes in the string up to and not including the * character as follows:

int cs = 0; for(i = 0; cmd[i] != '*' && cmd[i] != NULL; i++) cs = cs ^ cmd[i]; cs &= 0xff; // Defensive programming...

and the value is appended as a decimal integer to the command after the * character.

If buffering is supported, the RepRap firmware stores some commands in a ring buffer internally for execution. This means that there is no (appreciable) delay while a command is acknowledged and the next transmitted. In turn, this means that sequences of line segments can be plotted without a dwell between one and the next. As soon as one of these buffered commands is received it is acknowledged and stored locally. If the local buffer is full, then the acknowledgment is delayed until space for storage in the buffer is available. This is how flow control is achieved.

Typically, the following moving commands are buffered: G0-G3 and G28-G32. The Teacup Firmware buffers also some setting commands: G20, G21, G90 and G91. All other G, M or T commands are not buffered.

RepRapFirmware also implements an internal queue to ensure that certain codes (like M106) are executed in the right order and not when the last move has been added to the look-ahead queue.

When an unbuffered command is received it is stored, but it is not acknowledged to the host until the buffer is exhausted and then the command has been executed. Thus the host will pause at one of these commands until it has been done. Short pauses between these commands and any that might follow them do not affect the performance of the machine.

Znnn The position to move to on the Z axis

Ennn The amount to extrude between the starting point and ending point

Fnnn The feedrate per minute of the move between the starting point and ending point (if supplied)

Snnn Flag to check if an endstop was hit (S1 to check, S0 to ignore, S2 see note, default is S0)¹

Примеры

G0 X12  ; move to 12mm on the X axis G0 F1500  ; Set the feedrate to 1500mm/minute G1 X90.6 Y13.8 E22.4 ; Move to 90.6mm on the X axis and 13.8mm on the Y axis while extruding 22.4mm of material

The RepRap firmware spec treats G0 and G1 as the same command, since it's just as efficient as not doing so.²

Most RepRap firmwares do subtle things with feedrates.

G1 F1500  ; Set feedrate to 1500mm/m G1 X50 Y25.3 E22.4 ; Move and extrude

In the above example, we first set the feedrate to 1500mm/m, then move to 50mm on X and 25.3mm on Y while extruding 22.4mm of filament between the two points.

G1 F1500  ; Feedrate 1500mm/m G1 X50 Y25.3 E22.4 F3000 ; Accelerate to 3000mm/m

However, in the above example, we set a feedrate of 1500 mm/m, then do the same move, but accelerating to 3000 mm/m. Everything stays synchronized, so extrusion accelerates right along with X and Y movement.

The RepRap spec treats the feedrate as simply another variable (like X, Y, Z, and E) to be linearly interpolated. This gives complete control over the acceleration and deceleration of the printer head in a way that ensures everything moves smoothly together and the right volume of material is extruded at all points.³

To reverse the extruder by a given amount (for example to reduce its internal pressure while it does an in-air movement so that it doesn't dribble) simply use G0 or G1 to send an E value that is less than the currently extruded length.

Примечания

¹Some firmwares allow for the RepRap to enable or disable the "sensing" of endstops during a move. Please check with whatever firmware you are using to see if they support the S parameter in this way, as damage may occur if you assume incorrectly. In RepRapFirmware, using the S1 or S2 parameter on a delta printer causes the XYZ parameters to refer to the individual tower motor positions instead of the head position, and to enable endstop detection as well if the parameter is S1.

²In the RS274NGC Spec, G0 is Rapid Move, which was used to move between the current point in space and the new point as quickly and efficiently as possible, and G1 is Controlled Move, which was used to move between the current point in space and the new point as precise as possible.

³Some firmwares may not support setting the feedrate inline with a move.

⁴RepRapFirmware provides an additional 'R1' parameter to tell the machine to go back to the coordinates a print was previously paused at. If this parameter is used and the code contains axis letters, an offset will be added to the pause coordinates (e.g. G1 R1 Z5).

Some older machines, CNC or otherwise, used to move faster if they did not move in a straight line. This is also true for some non-Cartesian printers, like delta or polar printers, which move easier and faster in a curve.

Perform a direct, uninterpolated, and non-kinematic synchronized move of one or more steppers directly. Units may be linear (e.g., mm or inches on DELTA) or specified in degrees (SCARA). This command is useful for initialization, diagnostics, and calibration, and should be disabled on production equipment. This type of move can be potentially dangerous, especially for deltabots, so implementations should do their best to limit movement to prevent twerking and damaging the carriage assembly.

Remember that any parameter that you don't specify will automatically be set to the last value for that parameter. That usually means that you want explicitly to set Z0.0. RepRapFirmware will report the tool parameters if only the tool number is specified.

The precise meaning of the X, Y (and other offset) values is: with no offset this tool is at this position relative to where a tool with offset (0, 0, 0) would be. So if the tool is 10mm to the left of a zero-offset tool the X value would be -10, and so on.

The R value is the standby temperature in ^oC that will be used for the tool, and the S value is its operating temperature. If you don't want the tool to be at a different temperature when not in use, set both values the same. See the T code (select tool) below. In tools with multiple heaters the temperatures for them all are specified thus: R100.0:90.0:20.0 S185.0:200.0:150.0 .

См. также M585.

Примечания

¹Marlin uses G10/G11 for executing a retraction/unretraction move. The RepRapPro version of Marlin supports G10 for tool offset. Smoothie uses G10 for retract and G10 Ln for setting workspace coordinates.

²It's usually a bad idea to put a non-zero Z value in as well unless the tools are loaded and unloaded by some sort of tool changer or are on indepedent carriages. When all the tools are in the machine at once they should all be set to the same Z height.

³If the absolute zero temperature (-273.15) is passed as active and standby temperatures, RepRapFirmware will only switch off the tool heater(s) without changing their preset active or standby temperatures. RepRapFirmware-dc42 does not support this setting.

⁴The NIST G-code standard mentions an additional L parameter, which is ignored (except in smoothie). This command is subject to discussion.

⁵Tool offsets are applied after any X axis mapping has been performed. Therefore if for example you map X to U in your M563 command to create the tool, you should specify a U offset not an X offset. If you map X to both X and U, you can specify both offsets.

The G26 Mesh Validation Pattern is designed to be used in conjunction with various Mesh Bed Leveling systems � those that adjust for an uneven �rather than just tilted� bed. The G26 command prints a single layer pattern over the entire print bed, giving a clear indication of how accurately every mesh point is defined. G26 can be used to determine which areas of the mesh are less-than-perfect and how much to adjust each mesh point.

G26 has large feature list, including a built-in test that extrudes material onto the bed. By default this is configured for PLA temperatures and a nozzle size of 0.4mm. (This will be adjustable in an upcoming version of Marlin.)

See the G26_Mesh_Validation_Tool.cpp file in the Marlin source code for full documentation of the G26 parameter list.

This command can be used without any additional parameters.

X Flag to go back to the X axis origin

Y Flag to go back to the Y axis origin

Z Flag to go back to the Z axis origin

Примеры

G28  ; Home all axes G28 X Z ; Home the X and Z axes

When the firmware receives this command, it quickly moves the specified axes (or all axes if none are given) to the endstops, backs away from each endstop by a short distance, and slowly bumps the endstop again to increase positional accuracy. This process, known as "Homing", is required to determine the position of the print carriage(s). Some firmware may even forbid movement away from endstops and other operations until the axes have been homed.

The X, Y, and Z parameters act only as flags. Any coordinates given are ignored. For example, G28 Z10 results in the same behavior as G28 Z. Delta printers cannot home individual axes, but must always home all three towers, so the X Y Z parameters are simply ignored on these machines.

Marlin firmware (version 1.1.0 and later) provides an option called Z_SAFE_HOMING for printers that use a Z probe to home Z instead of an endstop. With this option, the XY axes are homed first, then the carriage moves to a position �usually the middle of the bed� where it can safely probe downward to home Z.

RepRapFirmware uses macro files to home either all axes or individual axes. If all axes are homed, the file homeall.g is processed. For individual axes the homex.g, homey.g, or homez.g file will be used. On Delta printers, G28 command will always home all three towers by processing the homedelta.g file, regardless of any X Y Z parameters.

Because the behavior of G28 is unspecified, it is recommended not to automatically include G28 in your ending GCode. On a Cartesian this will result in damaging the printed object. If you need to move the carriage at the completion of a print, use G0 or G1.

Примечания

¹ MK4duo has a B parameter that tells the printer to return to the coordinates it was at before homing.
² Original Prusa i3 Mk2/Mk3 supports a W parameter to suppress mesh bed leveling. If W is omitted, G28 will home and perform mesh bed leveling.

This command uses a probe to measure the bed height at 3 or more points to determine its tilt and overall flatness. It then enables compensation so that the nozzle will remain parallel to the bed. The printer must be homed with G28 before using this command.

Each firmware behaves differently and depends on the type of bed leveling that's been configured. For example, Marlin 1.0.2 provides 3 different types of automatic bed leveling (probe required) and a manual bed leveling option. See your firmware's documentation for the specific options available.

G29 Auto Bed Leveling (Marlin)

Marlin 1.0.2 and earlier provides three options for automatic bed leveling:

• The 3-point method probes the bed at three points to produce a matrix, adjusting for a flat but tilted bed.
• The planar grid method (non-Delta) probes a grid pattern to produce a matrix by the "least-squares" method, adjusting for a flat but tilted bed.
• The bilinear grid method (Delta only) probes a grid pattern to produce a mesh, using bilinear interpolation to adjust for an uneven bed.

Marlin 1.1.0 and later allows the bilinear grid (i.e., "mesh") method to be used on all types of machines, not just deltas. This is the recommended leveling method going forward.

Also in Marlin 1.1.0 and later, the PROBE_MANUALLY option allows all forms of Auto Bed Leveling to be used without a probe. The procedure is similar to that of MESH_BED_LEVELING (see below). Begin the process with G29 to move the nozzle to the first point. Adjust the Z axis using G1 or your host software. Send G29 again to move to the next point and repeat until all points have been sampled.

Параметры

P Set the size of the grid that will be probed (P x P points). Not supported by non-linear delta printer bed leveling. Пример: G29 P4

S Set the XY travel speed between probe points (in units/min)

D Dry-Run mode. Just evaluate the bed Topology - Don't apply or clean the rotation Matrix. Useful to check the topology after a first run of G29.

V Set the verbose level (0-4). Пример: G29 V3

T Generate a Bed Topology Report. Пример: G29 P5 T for a detailed report. This is useful for manual bed leveling and finding flaws in the bed (to assist with part placement). Not supported by non-linear delta printer bed leveling.

F Set the Front limit of the probing grid

B Set the Back limit of the probing grid

L Set the Left limit of the probing grid

R Set the Right limit of the probing grid

Global Parameters

E By default G29 will engage the Z probe, test the bed, then disengage. Include E or E1 to engage/disengage the Z probe for each sample. (This has no effect for fixed probes.)

G29 Unified Bed Leveling (Marlin)

Marlin firmware (version 1.1.0 and later) includes the AUTO_BED_LEVELING_UBL option for Unified Bed Leveling. UBL combines mesh leveling, tilted plane adjustment, 3-point leveling, and manual editing tools all together in a single package. To accomplish so much, UBL overloads `G29` with several new parameters and provides an additional G26 Mesh Tuning feature.

See the MarlinFW website for a dedicated Unified Bed Leveling page and complete documentation on `G29` for UBL and `G26` Mesh Validation.

G29 Manual Bed Leveling (Marlin)

Marlin firmware (version 1.0.2 and later) also provides a MESH_BED_LEVELING feature that can be used to perform bed leveling on machines lacking a probe. This form of bed leveling compensates for uneven Z height across the surface of the bed using a mesh and bilinear interpolation.

Manual Bed Leveling Usage

G29 S1 ; Move to the first point and wait for a measurement G29 S2 ; Store the current Z, move to the next point G29 S3 Xn Yn Zn.nn ; Modify the Z height of a single point

Options for the S parameter

S0 Produces a mesh report

S1 Start probing mesh points

S2 Probe the next mesh point

S3 Xn Yn Zn.nn Manually modify a single point

S4 Zn.nn Set z offset. Positive away from bed, negative closer to bed.

G29 Auto Bed Leveling (Repetier-Firmware)

Repetier firmware since v0.91 supports G29 with the optional Snnn parameter as described below. Useful to simply detect the Z bed angle so you can manually readjust your bed and get it as close to in plane as possible. If you wish to apply automatic software Z plane compensation on Repetier, use G32 instead with firmware 0.92.8 and above.

S0 Default value. Z bed heights are calculated at the measured points, relative to current Z position before issuing G29.

S1 Same as S0, except printer immediately moves to Z maximum position (Z max endstop required!), and calculates new Z maximum height. You must first issue G28 Z to home to Z maximum position before issuing G29 Snnn for this to work correctly, or the printer height will be invalid.

S2 Same as S1, except new calculated Z height is also stored to EEPROM.

G29 Auto Bed Compensation(RepRapFirmware)

RepRapFirmware:

S0 (default if no S parameter) Probe the bed, save the height map in a file on the SD card, and activate the height map. The default folder for the height map file is /sys and the default file name is heightmap.csv.

S1 Load the height map from file and activate bed compensation. The default folder and filename as for S0.

S2 Clear the currently-loaded bed height map

In its simplest form probes bed at current XY location.

RepRapFirmware supports additional behaviour: if a Pn field is specified the probed X, Y, and Z values are saved as point n on the bed for calculating the offset plane or for performing delta printer calibration. If X, Y, or Z values are specified (e.g. G30 P1 X20 Y50 Z0.3) then those values are used instead of the machine's current coordinates. A silly Z value (less than -9999.0) causes the machine to probe at the current point to get Z, rather than using the given value. If an S field is specified (e.g. G30 P1 Z0.3 S) the bed plane is computed for compensation and stored. The combination of these options allows for the machine to be moved to points using G1 commands, and then probe the bed, or for the user to position the nozzle interactively and use those coordinates. The user can also record those values and place them in a setup GCode file for automatic execution.

RepRapFirmware uses the value of the S parameter to specify what computation to perform. If the value is -1 then the Z offsets of all the points probed are printed, but no calibration is done. If the value is zero or not present, then this specifies that the number of factors to be calibrated is the same as the number of points probed. Otherwise, the value indicates the number of factors to be calibrated, which must be no greater than the number of points probed. In version 1.09, the number of factors may be 3, 4 or 5 when doing auto bed compensation on a Cartesian or CoreXY printer, and 3, 4, 6 or 7 when doing auto calibration of a Delta printer.

RepRapFirmware supports an optional H parameter, which is a height correction for that probe point. It allows for the Z probe having a trigger height that varies with XY position. The nominal trigger height of the Z probe (e.g. at bed centre) is declared in the Z parameter of the G31 command in the config.g file. When you probe using G30 and the probe triggers, the firmware will assume that the nozzle is at the nominal trigger height plus the value you have in the H parameter.

¹MK4duo Firmware support an optional parameter for Autocalibration Delta.

When used on its own this reports whether the Z probe is triggered, or gives the Z probe value in some units if the probe generates height values. If combined with a Z and P field (example: G31 P312 Z0.7) this will set the Z height to 0.7mm when the Z-probe value reaches 312 when a G28 Z0 (zero Z axis) command is sent. The machine will then move a further -0.7mm in Z to place itself at Z = 0. This allows non-contact measuring probes to approach but not touch the bed, and for the gap left to be allowed for. If the probe is a touch probe and generates a simple 0/1 off/on signal, then G31 Z0.7 will tell the RepRap machine that it is at a height of 0.7mm when the probe is triggered.

In RepRapFirmware, separate G31 parameters may be defined for different probe types (i.e. 0+4 for switches, 1+2 for IR probes and 3 for alternative sensors). To specify which probe you are setting parameters for, send a M558 command to select the probe type before sending the G31 command, or use the T parameter.

In Repetier, G31 supports no parameters and simply prints the high/low status of the Z probe.

Примечания

¹X and Y offsets of the Z probe relative to the print head (i.e. the position when the empty tool is selected) can be specified in RepRapFirmware. This allows you to calculate your probe coordinates based on the geometry of the bed, without having to correct them for Z probe X and Y offset.

²In RepRapFirmware, additional parameters 'S' (bed temperature in ^oC at which the specified Z parameter is correct, default is current bed temperature) and 'C' (temperature coefficient of Z parameter in mm/^oC, default zero) can be set for the alternative (ultrasonic) sensor. This is useful for probes that are affected by temperature. This facility is deprecated and likely to be removed in a future version of RepRapFirmware.

This command is implemented as a more sophisticated form of bed leveling (which uses a transformation matrix or motorized correction. Smoothieware uses this code instead of `G29`.

Each firmware behaves differently. For example, Repetier firmware allows for motorized rotation of the bed whilst ReprapFirmware probes the bed with a transformation matrix.

Snnn Bed leveling method

Pnnn Bed correction method

The values for Snnn and Pnnn are as follows:

S0 This method measures at the 3 probe points and creates a plane through these points. If you have a really planar bed this gives the optimum result. The 3 points must not be in one line and have a long distance to increase numerical stability.

S1 This measures a grid. Probe point 1 is the origin and points 2 and 3 span a grid. We measure BED_LEVELING_GRID_SIZE points in each direction and compute a regression plane through all points. This gives a good overall plane if you have small bumps measuring inaccuracies.

S2 Bending correcting 4 point measurement. This is for cantilevered beds that have the rotation axis not at the side but inside the bed. Here we can assume no bending on the axis and a symmetric bending to both sides of the axis. So probe points 2 and 3 build the symmetric axis and point 1 is mirrored to 1m across the axis. Using the symmetry we then remove the bending from 1 and use that as plane.

P0 Use a rotation matrix. This will make z axis go up/down while moving in x/y direction to compensate the tilt. For multiple extruders make sure the height match the tilt of the bed or one will scratch. This is the default.

P1 Motorized correction. This method needs a bed that is fixed on 3 points from which 2 have a motor to change the height. The positions are defined in firmware by BED_MOTOR_1_X, BED_MOTOR_1_Y, BED_MOTOR_2_X, BED_MOTOR_2_Y, BED_MOTOR_3_X, BED_MOTOR_3_Y Motor 2 and 3 are the one driven by motor driver 0 and 1. These can be extra motors like Felix Pro 1 uses them or a system with 3 z axis where motors can be controlled individually like the Sparkcube does. This method requires a Z max endstop.

G60 Snn

Параметры

Snn <nn> specifies memory slot # (0-based) to save into (default 0)

Implementation in RepRapFirmware:

• Only slots 0, 1 and 2 are available. When a print is paused the coordinates are saved to slot 1 automatically, and at the start of a tool change the coordinates are saved to slot 2 automatically. Use G0 or G1 with the R0, R1 or R2 parameter to move the current tool to a saved position.

G61: Apply/restore saved coordinates to the active extruder.

Например

G92 X10 E90

Allows programming of absolute zero point, by reseting the current position to the values specified. This would set the machine's X coordinate to 10, and the extrude coordinate to 90. No physical motion will occur.

A G92 without coordinates will reset all axes to zero on some firmware. This does not apply to RepRapFirmware.

	???	???	???	???	???	???	Нет	???	???	Да	Нет	Нет

G93 is Inverse Time Mode. In inverse time feed rate mode, an F word means the move should be completed in (one divided by the F number) minutes. For example, if the F number is 2.0, the move should be completed in half a minute.

When the inverse time feed rate mode is active, an F word must appear on every line which has a G1, G2, or G3 motion, and an F word on a line that does not have G1, G2, or G3 is ignored. Being in inverse time feed rate mode does not affect G0 (rapid move) motions.

Pnnn Time to wait, in milliseconds¹

Snnn Time to wait, in seconds²

Например

M0

The RepRap machine finishes any moves left in its buffer, then shuts down. All motors and heaters are turned off. It can be started again by pressing the reset button on the master microcontroller, although this step is not mandatory on RepRapFirmware. See also M1, M112.

The Marlin Firmware does wait for user to press a button on the LCD, or a specific time. "M0 P2000" waits 2000 milliseconds, "M0 S2" waits 2 seconds.

RepRapFirmware executes macro file stop.g before everything is turned off. Apart from that, RepRapFirmware (v1.09n-ch) accepts an extra 'H' parameter, whose value must be non-zero, to keep all heaters active. This is what Duet Web Control v1.07 sends to cancel a paused print.

Примечания

¹Not available in RepRapFirmware, but as a work-around G4 can be run before M0.

²Only available on Marlin.

Snnn Output style¹

Pnnn Directory to list²

Примеры

M20 M20 S2 P/gcodes/subdir

This code lists all files in the root folder or G-code directory of the SD card to the serial port. One name per line, like:

ok SQUARE.G SQCOM.G ZCARRI~2.GCO CARRIA~1.GCO

On Marlin, a file list response is usually encapsulated. Standard configurations of RepRapFirmware mimic this style in emulation mode:

Begin file list: SQUARE.G ZCARRI~2.GCO End file list ok

If RepRapFirmware emulates no firmware compatibility, a typical response looks like:

GCode files: "Traffic cone.g","frog.gcode","calibration piece.g"

Note that some firmwares list file names in upper case, but - when sent to the M23 command (below) they must be in lower case. Teacup and RepRapFirmware have no such trouble and accept both. RepRapFirmware always returns long filenames in the case in which they are stored.

Примечания

¹If the S2 parameter is used on RepRapFirmware, then the file list is returned in JSON format as a single array called "files" with each name that corresponds to a subdirectory preceded by an asterisk, and the directory is returned in variable "dir".

Например

M20 S2 P/gcodes {"dir":"\/gcodes","files":["4-piece-1-2-3-4.gcode","Hinged_Box.gcode","Hollow_Dodecahedron_190.gcode","*Calibration pieces"]}

²This parameter is only supported by RepRapFirmware and defaults to the 0:/gcodes directory, which is the directory that printable gcode files are normally stored in.

Например

M24

The machine prints from the file selected with the M23 command. If the print was previously paused with M25, printing is resumed from that point. To restart a file from the beginning, use M23 to reset it, then M24.

When this command is used to resume a print that was paused, RepRapFirmware runs macro file resume.g prior to resuming the print.

M25: Pause SD print

Например

M25

The machine pauses printing at the current position within the file. To resume printing, use M24. Do not use this code to pause the print in a G-code file, use M226 instead.

Prior to pausing, RepRapFirmware runs macro file pause.g. This allows the head to be moved away from the print, filament to be retracted, etc.

RepRapFirmware 1.20 and later also save the current state of the print to file /sys/resurrect.g. This is so that if the printer is turned off after pausing, the print can subsequently be resumed.

In Marlin 1.1.9 and up M27 C reports the open file's DOS 8.3 name and long filename, if any.

Например

M27 C

Current file: filena~1.gco Filenagotcha.gcode

In Marlin 1.1.9 and up M27 Sn sets the auto-report interval. This requires the AUTO_REPORT_SD_STATUS configuration option to be enabled. Marlin reports this capability in M115 as Cap: AUTO_REPORT_SD_STATUS 1 when this option is available.

Например

M36 filename.gco

Returns information for the specified SD card file in JSON format. A sample response is:

{"err":0,"size":457574,"height":4.00,"layerHeight":0.25,"filament":[6556.3],"generatedBy":"Slic3r 1.1.7 on 2014-11-09 at 17:11:32"}

The "err" field is zero if successful, nonzero if the file was not found or an error occurred while processing it. The "size" field should always be present if the operation was successful. The presence or absence of other fields depends on whether the corresponding values could be found by reading the file. The "filament" field is an array of the filament lengths required from each spool. The size is in bytes, all other values are in mm. The fields may appear in any order, and additional fields may be present.

If the file name parameter is not supplied and a file on the SD card is currently being printed, then information for that file is returned including additional field "fileName". This feature is used by the web interface and by PanelDue, so that if a connection is made when a file is already being printed, the name and other information about that file can be shown.

Parameters

S1 Enter simulation mode

S0 Leave simulation mode

P"filename" (optional) Simulate printing a file from SD card

Examples

M37 S1

M37 P"MyModel.g"

Used to switch between printing mode and simulation mode. Simulation mode allows the electronics to compute an accurate printing time, taking into account the maximum speeds, accelerations etc. that are configured.

M37 S1 enters simulation mode. All G and M codes will not be acted on, but the time they would take to execute will be calculated.

M37 S0 leaves simulation mode and prints the total time taken by simulated moves since entering simulation mode.

If your RepRap machine can eject the parts it has built off the bed, this command executes the eject cycle. This usually involves cooling the bed and then performing a sequence of movements that remove the printed parts from it. The X, Y and Z position of the machine at the end of this cycle are undefined (though they can be found out using the M114 command, q.v.).

If the RepRap machine was building a file from its own memory such as a local SD card (as opposed to a file being transmitted to it from a host computer) this goes back to the beginning of the file and runs it again. So, for example, if your RepRap is capable of ejecting parts from its build bed then you can set it printing in a loop and it will run and run. Use with caution - the only things that will stop it are:

1. When you press the reset button,
2. When the build material runs out (if your RepRap is set up to detect this), and
3. When there's an error (such as a heater failure).

On Marlin, Repetier and RepRapFirmware, M84 can also be used to configure or disable the idle timeout. For example, "M84 S10" will idle the stepper motors after 10 seconds of inactivity. "M84 S0" will disable idle timeout; steppers will remain powered up regardless of activity.

Pnnn Macro filename

M98 Pmymacro.g

Runs the macro in the file mymacro.g. In conventional G Codes for CNC machines the P parameter normally refers to a line number in the program itself (P2000 would run the Macro starting at line O2000, say). For RepRap, which almost always has some sort of mass storage device inbuilt, it simply refers to the name of a GCode file that is executed by the G98 call. That GCode file does not need to end with an M99 (return) as the end-of-file automatically causes a return. RepRapFirmware supports nested macro calls up to a depth of 5.

Certain machine parameters are saved at the start of the macro call and restored at the end. For RepRapFirmware these are: axis movement relative/absolute mode, extruder movement absolute/relative mode, feed rate.

RepRapFirmware also allows the filename to include a path to a subdirectory. For relative paths, the default folder is /sys, but some implementations may check the /macros directory too. Absolute file paths are supported on RepRapFirmware too.

Первый пример включает охлаждающий вентилятор по умолчанию с половиной скоростью. The second one inverts the cooling fan signal of the second fan and sets its value to 1/3 of its maximum. The third one sets the second fan to a thermostatic fan for heaters 1 and 2 (e.g. the extruder heaters in a dual-nozzle machine) such that the fan will be on when either hot end is at or above 45C.

Mandatory parameter 'S' declares the PWM value (0-255). M106 S0 turns the fan off. In some implementations like RepRapFirmware the PWM value may alternatively be specified as a real fraction: M106 S0.7.

Примечания

¹These parameters are only available in RepRapFirmware.

²Marlin 1.0 to 1.1.6 only supports a single fan. Marlin 1.1.7 and up supports up to 3 fans.

M106 в RepRapFirmware

If an S parameter is provided but no other parameter is present, then the speeds of the print cooling fans associated with the current tool will be set (see the F parameter in the M563 command). If no tool is active then the speed of Fan 0 will be set. Either way, the speed is remembered so that it can be recalled using the R2 parameter (see below).

If no S parameter is given but the R1 parameter is used, the fan speed when the print was last paused will be set. If the R2 parameter is used, then the speeds of the print cooling fans associated with the current tool will be set to the remembered value (see above).

The T and H parameters allow a fan to be configured to operate in thermostatic mode, for example to use one of the fan channels to control the hot end fan. In this mode the fan will be fully on when the temperature of any of the heaters listed in the H parameter is at or above the trigger temperature set by the T parameter, and off otherwise. Thermostatic mode can be disabled using parameter H-1.

The B parameter sets the time for which the fan will be operated at full PWM when started from cold, to allow low fan speeds t be used. Обычно достаточное значение 0.1 секунды.

Параметр L определяет минимальное значение ШИМ, которое может использоваться с этим вентилятором. If a lower value is commanded that is not zero, it will be rounded up to this value. The X parameter defines the maximum PWM value that is allowed for this fan. If a higher value is commanded, it will be rounded down to this value.

The I parameter causes the fan output signal to be inverted if its value is greater than zero. This makes the cooling fan output suitable for feeding the PWM input of a 4-wire fan via a diode. If the parameter is present and zero, the output is not inverted. If the I parameter is negative then in RRF 1.16 and later the fan is disabled, which frees up the pin for use as a general purpose I/O pin that can be controlled using M42.

M106 в Teacup Firmware

Кроме того, прошивка использует M106 для управления общими устройствами. It supports the additional P parameter, which is an zero-based index into the list of heaters/devices in config.h.

Например

M106 P2 S255

Turn on device #3 at full speed/wattage.

Note: When turning on a temperature sensor equipped heater with M106 and M104 at the same time, temperature control will override the value given in M106 quickly.

Note well: The ambiguous text in the note above needs to be reworded by someone who knows the actual functioning. Below is my interpretation based on language use, not practical experience or code inspection.

Note: If M104 is (or becomes) active on a heater (or other device) with a feedback sensor it will correct any M106 initiated control output value change in the time it takes for the PID (of other feedback) loop to adjust it back to minimum error. It may not be easy to observe a change in the temperature (process value) due to this brief change in the control value

M109 in Teacup

Not needed. To mimic Marlin behaviour, use M104 followed by M116.

M109 in Marlin, Sprinter (ATmega port), RepRapFirmware

Set extruder heater temperature in degrees celsius and wait for this temperature to be achieved.

Например

M109 S185

RepRapFirmware also supports the optional T parameter (as generated by slic3r) to specify which tool the command refers to (see below).

M109 in Sprinter (4pi port)

Parameters: S (optional), set target temperature value. If not specified, waits for the temperature set by M104. R (optional), sets target temperature range maximum value.

Например

M109 S185 R240 ; set extruder temperature to 185 and wait for the temperature to be between 185 - 240.

If you have multiple extruders, use T or P parameter to specify which extruder you want to set/wait.

Another way to do this is to use G10.

M109 in MakerBot

Например

M109 S70 T0

Sets the target temperature for the current build platform. S is the temperature to set the platform to, in degrees Celsius. T is the platform to heat.

Примеры

M111 S6 M111 P1 S1

Enable or disable debugging features in the firmware. The implementation may look different per firmware.

Примечания

¹This parameter is only available in RepRapFirmware.

M111 in RepRapFirmware

RepRapFirmware allows debugging to be set for each module. If the optional 'P' parameter is not specified, debugging will be enabled for all modules. For a list of modules, send M111 S1 P15.

M111 in Repetier

Set the level of debugging information transmitted back to the host to level 6. The level is the OR of three bits:

1. define DEBUG_ECHO (1<<0)
2. define DEBUG_INFO (1<<1)
3. define DEBUG_ERRORS (1<<2)
4. define DEBUG_DRYRUN (1<<3) // repetier-firmware
5. define DEBUG_COMMUNICATION (1<<4) // repetier-firmware

Thus 6 means send information and errors, but don't echo commands. (This is the RepRap default.)

For firmware that supports ethernet and web interfaces M111 S9 will turn web debug information on without changing any other debug settings, and M111 S8 will turn it off. Web debugging usually means that HTTP requests will be echoed to the USB interface, as will the responses.

Set the PWM for the currently-selected extruder. On its own this command sets RepRap to use the on-board potentiometer on the extruder controller board to set the PWM for the currently-selected extruder's stepper power. With an S field:

M113 S0.7

it causes the PWM to be set to the S value (70% in this instance). M113 S0 turns the extruder off, until an M113 command other than M113 S0 is sent.

This causes the RepRap machine to report its current X, Y, Z and E coordinates to the host.

For example, the machine returns a string such as:

ok C: X:0.00 Y:0.00 Z:0.00 E:0.00

In Marlin first 3 numbers is the position for the planner. The other positions are the positions from the stepper function. This helps for debugging a previous stepper function bug.

This M115 code is inconsistently implemented, and should not be relied upon to exist, or output correctly in all cases. An initial implementation was committed to svn for the FiveD Reprap firmware on 11 Oct 2010. Work to more formally define protocol versions is currently (October 2010) being discussed. See M115_Keywords for one draft set of keywords and their meanings. See the M408 command for a more comprehensive report on machine capabilities supported by RepRapFirmware.

Wait for all temperatures and other slowly-changing variables to arrive at their set values if no parameters are specified. See also M109.

Примечания

¹Most implementations don't support any parameters, but RepRapFirmware version 1.04 and later supports an optional 'P' parameter that is used to specify a tool number. If this parameter is present, then the system only waits for temperatures associated with that tool to arrive at their set values. This is useful during tool changes, to wait for the new tool to heat up without necessarily waiting for the old one to cool down fully.

Recent versions of RepRapFirmware also allow a list of the heaters to be specified using the 'H' parameter, and if the 'C' parameter is present, this will indicate that the chamber heater should be waited for.

This causes the RepRap machine to report the X, Y, Z and E coordinates in steps not mm to the host that it found when it last hit the zero stops for those axes. That is to say, when you zero X, the x coordinate of the machine when it hits the X endstop is recorded. This value should be 0, of course. But if the machine has drifted (for example by dropping steps) then it won't be. This command allows you to measure and to diagnose such problems. (E is included for completeness. It doesn't normally have an endstop.)

Teacup can control multiple heaters with independent PID controls. For the default shown at https://github.com/Traumflug/Teacup_Firmware/blob/master/config.default.h, heater 0 is the extruder (P0), and heater 1 is the bed (P1).

Teacup's PID proportional units are in pwm/255 counts per quarter C, so to convert from counts/C, you would divide by 4. Conversely, to convert from count/qC to count/C, multiply by 4. In the above example, S=8 represents a Kp=8*4=32 counts/C.

Hosts normally monitor printer temperatures by sending M105 every x seconds. This not only adds traffic, but also only works while printer is not blocked by waiting commands. So frequency more depends on frequency you can send new commands and creates extra traffic. As a solution, firmware can be told to automatically send temperatures every second. This function is disabled by default for best compatibility with existing hosts. To indicate the availability of this function, M115 will add an extra line:

Параметры

Daaa:bbb:ccc... Sets filament diameter to aaa for extruder 0, bbb for extruder 1 and so on. If any of aaa, bbb etc. are zero then volumetric extrusion is disabled for that extruder.

Daaa Sets filament diameter (or disables volumetric extrusion) for all extruders

Примеры

M200 D0  ; disable volumetric extrusion on all extruders

M200 D1.75  ; set al extruder filament diameters to 1.75mm

M200 D1.75:3.0:1.75  ; set extruder 0 to 1.75mm, extruder 1 to 3.0mm and all remaining extruders to 1.75mm

Volumetric extrusion is an option you can set in some slicers whereby all extrusion amounts are specified in mm³ (cubic millimetres) of filament instead of mm of filament. This makes the gcode independent of the filament diameter, potentially allowing the same gcode to run on different printers. The purpose of the M200 command is to inform the firmware that the gcode input files have been sliced for volumetric extrusion, and to provide the filament diameter so that the firmware can adjust the requested extrusion amount accordingly.

Sending M200 without parameters reports the current volumetric extrusion state and (where appropriate) filament diameter for each extruder.

Note that if you use slicer-commanded retraction, the retraction amounts must be specified in mm³ too. If instead you use firmware retraction, then the firmware retraction amounts specified using the M207 command are still interpreted as mm.

Other firmwares:

Without parameters loads default grid, and with specified extension attempts to load the specified grid. If not available will not modify the current grid. If Z was saved with the grid file, it will load the saved Z with the grid.

M200 Dm.mmm sets the filament diameter to m.mmm millimeters. It is used with 'volumetric calibration' and G-code generated for an ideal 1.128mm diameter filament, which has a volume of 1mm^3 per millimeter. The intention is to be able to generate filament-independent g-code. (See Triffid_Hunter's_Calibration_Guide#Optional:_Switch_to_volumetric_E_units and http://wooden-mendel.blogspot.com/2011/09/volumetric-stage-two.html for more information.)

M200 D0 or M200 D1.128 ; reset E multiplier to 1, since sqrt(1 / pi) * 2 = 1.128

Question: what does a firmware do with filament diameter? Has this an effect on how much an E command moves the extruder motor? --Traumflug 11:34, 14 October 2012 (UTC) Yes, Marlin uses this to set a 'volumetric_multiplier' by which the E-steps of a move are scaled in the planner.

Parameters (RepRapFimware)

Pnnn Acceleration for printing moves

Tnnn Acceleration for travel moves

Например

M204 P500 T2000

Use M201 to set per-axis accelerations and extruder accelerations. RepRapFirmware applies the M204 accelerations to the move as a whole, and also applies the limits set by M201 to each axis and extruder.

Other firmwares:

S normal moves T filament only moves (M204 S3000 T7000) im mm/sec^2 also sets minimum segment time in ms (B20000) to prevent buffer underruns and M20 minimum feedrate

Marlin notes: After Mar11-2015, the M204 options have changed in Marlin:

P = Printing moves

R = Retract only (no X, Y, Z) moves

T = Travel (non printing) moves

The command M204 P800 T3000 R9000 sets the acceleration for printing movements to 800mm/s^2, for travels to 3000mm/s^2 and for retracts to 9000mm/s^2.

After placing the tip of the nozzle in the position you expect to be considered Z=0, issue this command to calibrate the Z axis. It will perform a z axis homing routine and calculate the distance traveled in this process. The result is stored in EEPROM as z_max_length. For using this calibration method the machine must be using a Z MAX endstop.

This procedure is usually more reliable than mechanical adjustments of a Z MIN endstop.

Both M260 and M261 are commands demonstrating use of the i2c bus (TWIBus class) in Marlin Firmware. Developers and vendors can make Marlin an i2c master device by enabling EXPERIMENTAL_I2CBUS, and Marlin can act as a slave device by setting I2C_SLAVE_ADDRESS from 8-127. This class can be used to divide up processing responsibilities between multiple instances of Marlin running on multiple boards. For example, one board might control a Z axis with 4 independent steppers to create a self-leveling system, or a second board could drive the graphical display while the first board handles printing.

Параметры

Pnnn Servo index

Snnn Angle or microseconds

I1 Invert polarity (RepRapFirmware only)

Например

M280 P1 S50

Marlin and RepRapFirmware treat S values below 200 as angles, and 200 or greater as the pulse width in microseconds.

In RepRapFirmware, the servo index is the same as the pin number for the M42 command. See https://duet3d.com/wiki/Using_servos_and_controlling_unused_I/O_pins for details.

RepRapFirmware supports the optional I1 parameter, which if present causes the polarity of the servo pulses to be inverted compared to normal for that output pin. The I parameter is not remembered between M280 commands (unlike the I parameter in M106 commands), so if you need inverted polarity then you must include I1 in every M280 command you send.

Parameters (RepRapFirmware)

Snnn Amount to baby step in mm. Positive values raise the head, negative values lower it.

Znnn Synonym for S (RepRapFirmware 1.21 and later)

Rn (Optional, RepRapFirmware 1.21 and later) R1 = relative (add to any existing babystep amount, the default), R0 = absolute (set babystepping offset to the specified amount)

Примеры

M290 S0.05  ; babystep the head up 0.05mm M290 R0 S0  ; clear babystepping (RepRapFirmware 1.21 and later only)

Additional Parameters (Marlin 1.1.7 and later)

Xnnn Amount to babystep X in current units. (Requires BABYSTEP_XY)

Ynnn Amount to babystep Y in current units. (Requires BABYSTEP_XY)

Znnn Amount to babystep Z in current units. Synonym for 'S' parameter.

Например

M290 X0.2 Z0.05 ; Babystep X by 0.2mm, Z by 0.05mm

This command tells the printer to move the axis (or axes) transparently to the motion system. This is like physically moving the axes by force, but much nicer to the machine.

In RepRapFirmware M290 with no parameters reports the accumulated baby stepping offset. Marlin doesn't track accumulated babysteps.

In RepRapFirmware 1.19 and earlier, the babystepping offset is reset to zero when the printer is homed or the bed is probed. In RepRapFirmware 1.21 and later, homing and bed probing don't reset babystepping, but you can reset it explicitly using M290 R0 S0.

Примечание: If the BABYSTEP_ZPROBE_OFFSET option is used in Marlin, this command also affects the Z probe offset (as set by M851) and that offset will be saved to EEPROM.

R"message" Optional title for the message box. Must be enclosed in double quotation marks too.

Sn Message box mode (defaults to 1)

Tn Timeout in seconds, only legal for S=0 and S=1. The message will be cancelled after this amount of time, if the user does not cancel it before then. A zero or negative value means that the message does not time out (it may still be cancelled by the user). In RepRapFirmware, the default timeout for messages that do not require acknowledgement is 10 seconds.

This command provides a more flexible alternative to M117, in particular messages that time out, messages that suspend execution until the user acknowledges them, and messages that allow the user to adjust the height of the print head before acknowledging them.

Allowed message box modes include:

0. No buttons are displayed (non-blocking) 1. Only "Close" is displayed (non-blocking) 2. Only "OK" is displayed (blocking, send M292 to resume the execution) 3. "OK" and "Cancel" are displayed (blocking, send M292 to resume the execution or M292 P1 to cancel the operation in progress)

Sets Proportional (P), Integral (I) and Derivative (D) values for hot end. See also PID Tuning.

Marlin

Hot end only; see M304 for bed PID. H is the heater number, default 1 (i.e. first extruder heater).

RepRapFirmware 1.15 onwards

In RepRapFirmware 1.15 and later the M301 is supported as described above, but it is not normally used. Instead the heater model is defined by M307 or found by auto tuning, and the firmware calculates the PID parameters from the model. An M301 command can be used in config.g after the M307 command for that heater to override the firmware-computed PID parameters.

RepRapFirmware 1.09 to 1.14 inclusive

• H Is the heater number, and is compulsory. H0 is the bed, H1 is the first hot end, H2 the second etc.
• P Interprets a negative P term as indicating that bang-bang control should be used instead of PID (not recommended for the hot end, but OK for the bed heater).
• I Integral value
• D Derivative value
• T Is the approximate additional PWM (on a scale of 0 to 255) needed to maintain temperature, per degree C above room temperature. Used to preset the I-accumulator when switching from heater fully on/off to PID.
• S PWM scaling factor, to allow for variation in heater power and supply voltage. Is designed to allow a correction to be made for a change in heater power and/or power supply voltage without having to change all the other parameters. For example, an S factor of 0.8 means that the final output of the PID controller should be scaled to 0.8 times the standard value, which would compensate for a heater that is 25% more powerful than the standard one or a supply voltage that is 12.5% higher than standard.
• W Wind-up. Sets the maximum value of I-term, must be high enough to reach 245C for ABS printing.
• B PID Band. Errors larger than this cause heater to be on or off.

An example using all of these would be: M301 H1 P20 I0.5 D100 T0.4 S1 W180 B30

Smoothie

S0<code> is 0 for the hotend, and 1 for the bed, other numbers may apply to your configuration, depending on the order in which you declare temperature control modules.

Other implementations

W: Wind-up. Sets the maximum value of I-term, so it does not overwhelm other PID values, and the heater stays on. (Check firmware support - Sprinter, Marlin?)

M301 W125

Teacup

See <code>M130, M131, M132, M133 for Teacup's codes for setting the PID parameters.

Examples (Others)

M302 S0  ; Allow extrusion at any temperature M302 S170  ; Allow extrusion above 170

This tells the printer to allow movement of the extruder motor above a certain temperature, or if disabled, to allow extruder movement when the hotend is below a safe printing temperature.

Примечания

¹RepRapFirmware uses the P[0|1] parameter instead of S[temperature], and for M302 with no parameters it will report the current cold extrusion state.

PID Tuning refers to a control algorithm used in some repraps to tune heating behavior for hot ends and heated beds. This command generates Proportional (Kp), Integral (Ki), and Derivative (Kd) values for the hotend or bed (E-1). Send the appropriate code and wait for the output to update the firmware.

Hot end usage: M303 S<temperature> C<cycles> Bed usage (repetier, not sure whether cycles work here): M303 P1 S<temperature> Bed usage (others): M303 E-1 C<cycles> S<temperature>

Например

M303 C8 S175 Smoothie's syntax, where E0 is the first temperature control module (usually the hot end) and E1 is the second temperature control module (usually the bed): M303 E0 S190 In RepRapFirmware, this command computes the process model parameters (see M307), which are in turn used to calculate the PID constants. H is the heater number, P is the PWM to use (default 0.5), and S is the maximum allowable temperature (default 225). Tuning is performed asynchronously. Run M303 with no parameters to see the current tuning state or the last tuning result.

Например

M303 H1 P0.4 S240 ; tune heater 1 using 40% PWM, quit if temperature exceeds 240C

Примечания

In Marlin Firmware you can add the U1 parameter to apply the PID results to current settings upon completion.

M304 in RepRapPro version of Marlin: Set thermistor values

In the RepRapPro version of Marlin ( https://github.com/reprappro/Marlin ) M304 is used to set thermistor values (as M305 is in later firmwares). RRP Marlin calculates temperatures on the fly, rather than using a temperature table. M304 Sets the parameters for temperature measurement.

Например

M304 H1 B4200 R4800 T100000

This tells the firmware that for heater 1 (H parameter: 0 = heated bed, H = first extruder), the thermistor beta (B parameter) is 4200, the thermistor series resistance (R parameter) is 4.8Kohms, the thermistor 25C resistance (T parameter) is 100Kohms. All parameters other than H are optional. If only the H parameter is given, the currently-used values are displayed. They are also displayed within the response to M503.

Cnnn Steinhart-Hart C coefficient (RepRapFirmware 1.17 and later), default 0

Rnnn Series resistor value

Lnnn ADC low offset correction, default 0

Hnnn ADC high offset correction, default 0

Xnnn Heater ADC channel, or thermocouple or PT100 or current loop adapter channel, defaults to the same value as the P parameter

Fnn (where nn is 50 or 60) If the sensor interface uses a MAX31856 thermocouple chip or MAX31865 PT100 chip, this is the local mains frequency. Readings will be timed to optimise rejection of interference at this frequency.

Например

M305 P1 T100000 R1000 B4200

Sets the parameters for temperature measurement. The example above tells the firmware that for heater 1 (P parameter: 0 = heated bed, 1 = first extruder) the thermistor 25C resistance (T parameter) is 100Kohms, the thermistor series resistance (R parameter) is 1Kohms, the thermistor beta (B parameter) is 4200. All parameters other than P are optional. If only the P parameter is given, the existing values are displayed.

Например

M305 P1 T100000 R1000 B4200 H14 L-11 X2

The H correction affects the reading at high ADC input voltages, so it has the greatest effect at low temperatures. The L correction affects the reading at low input voltages, which correspond to high temperatures.

The X parameter tells the firmware to use the thermistor input corresponding to a different heating channel. RepRapFirmware also allow an external SPI thermocouple interface (such as the MAX31855) or PT100 interface (MAX31865) to be configured. MAX31855 thermocouple channels are numbered from 100, MAX31856 thermocouple channels are numbered from 150, PT100 channels from 200 and current loop channels from 300. Channel 1000 is the CPU temperature indication, 1001 is the temperature of the hottest stepper motor driver on the main board, and 1001 is the temperature of the hottest drivers on the expansion board.

In the above example, the ADC high end correction (H parameter) is 14, the ADC low end correction (L parameter) is -11, and thermistor input #2 is used to measure the temperature of heater #1.

The values specified are added to the calculated end stop position when the axes are referenced. The calculated value is derived from the distance of the toolhead from the current axis zero point.

Snnn maximum PWM to be used used with this heater on a scale of 0 to 1. Default 1.0.

Vnnn VIN supply voltage at which the A parameter was calibrated (RepRapFirmware 1.20 and later). This allows the PID controller to compensate for changes in supply voltage. A value of zero disables compensation for changes in supply voltage.

Примеры

Each heater and its corresponding load may be approximated as a first order process with dead time, which is characterised by the gain, time constant and dead time parameters. The model can used to calculate optimum PID parameters (including using different values for the heating or cooling phase and the steady state phase), to better detect heater faults, and to calculate feed-forward terms to better respond to changes in the load. Normally these model parameters are found by auto tuning - see M303.

RepRapFirmware 1.16 and later allow the PID controller for a heater to be disabled by setting the A, C, and D parameters to -1. This frees up the corresponding heater control pin for use as a general purpose I/O pin to use with the M42 or M280 command.

The arms move into a position where the Theta steering arm is parallel to the top platform edge. The user then calibrates the position by moving the arms with the jog buttons in software like pronterface until it is perfectly parallel. Using M114 will then display the calibration offset that can then be programmed into the unit using M206 (Home offset) X represents Theta.

Smoothieware: M360 P0 will take the current position as parallel to the platform edge, and store the offset in the homing trim offset (M666) No further user interaction is needed.

Theta move to 90 degrees with platform edge. User calibrates by using jog arms to place exactly 90 degrees. Steps per degree can then be read out by using M114, and programmed using M92. X represents Theta. Program Y (Psi) to the same value initially. Remember to repeat M360 after adjusting steps per degree.

In Smoothieware, without parameters this saves the grid into the default grid file that gets loaded at boot. The optional parameter specifies the extension of the grid file - useful for special grid files such as for a special print surface like a removable print plate. Addition of Z will additionally save the M206 Z homing offset into the grid file.

In RepRapFirmware, this saves the grid parameters and height map into the specified file, or the default file heightmap.csv if no filename was specified. To load the height map automatically at startup, use command M375 in the config.g file.

Hnnn Height (mm) over which to taper off the bed compensation

Например

M376 H10

This command specifies that bed compensation should be tapered off over the specified height, so that no bed compensation is applied at and above that height. If H is zero or negative then no tapering is applied, so compensation is performed throughout the entire print.

If the firmware does not adjust the extrusion amount to compensate for the changing layer height while tapering is being applied, you will get under- or over-extrusion. Using a large taper height will reduce this effect. For example, if the taper height is 50 times the largest bed height error, then under- or over-extrusion will be limited to 2%.

Report a JSON-style response by specifying the desired type using the 'S' parameter.

The following response types are supported:

• Type 0 is a short-form response, similar to the response used by older versions of the web interface.
• Type 1 is like type 0 except that static values are also included.
• Type 2 is similar to the response provided by the web server for Duet Web Control.
• Type 3 is an extended version of type 2 which includes some additional parameters that aren't expected to change very frequently.
• Type 4 is an extended version of type 2 which may be used to poll for current printer statistics.
• Type 5 reports the current machine configuration.

Here is an example of a typical type 0 response:

{"status":"I","heaters":[25.0,29.0,28.3],"active":[-273.1,0.0,0.0],"standby":[-273.1,0.0,0.0],"hstat":[0,2,1],"pos":[-11.00,0.00,0.00],"extr":[0.0,0.0], "sfactor":100.00, "efactor":[100.00,100.00],"tool":1,"probe":"535","fanPercent":[75.0,0.0],"fanRPM":0,"homed":[0,0,0],"fraction_printed":0.572}

The response is set as a single line with a newline character at the end. The meaning of the fields is:

status: I=idle, P=printing from SD card, S=stopped (i.e. needs a reset), C=running config file (i.e starting up), A=paused, D=pausing, R=resuming from a pause, B=busy (e.g. running a macro), F=performing firmware update heaters: current heater temperatures, numbered as per the machine (typically, heater 0 is the bed) active: active temperatures of the heaters standby: standby temperatures of the heaters hstat: status of the heaters, 0=off, 1=standby, 2=active, 3=heater fault. Heater 0 is normally the bed heater, heaters 1, 2.. are the extruder heaters. pos: the X, Y and Z (and U, V, W if present) axis positions of the current tool (if a tool is selected), or of the print head reference point if no tool is selected extr: the positions of the extruders sfactor: the current speed factor (see M220 command) efactor: the current extrusion factors (see M221 command), one value per extruder tool: the selected tool number. A negative number typically means no tool selected. probe: the Z-probe reading fanPercent: the speeds of the controllable fans, in percent of maximum fanRPM: the print cooling fan RPM homed: the homed status of the X, Y and Z axes (and U, V, W if they exist), or towers on a delta. 0=axis has not been homed so position is not reliable, 1=axis has been homed so position is reliable. fraction_printed: the fraction of the file currently being printed that has been read and at least partially processed. message: the message to be displayed on the screen (only present if there is a message to display) timesLeft: an array of the estimated remaining print times (in seconds) calculated by different methods. These are currently based on the proportion of the file read, the proportion of the total filament consumed, and the proportion of the total layers already printed. Only present if a print from SD card is in progress. seq: the sequence number of the most recent non-trivial G-code response or error message. Only present if the R parameter was provided and the current sequence number is greater than that. resp: the most recent non-trivial G-code response or error message. Only present if the R parameter was provided and the current sequence number is greater.

The type 1 response comprises these fields plus some additional ones that do not generally change and therefore do not need to be fetched as often. The extra fields include:

myName: the name of the printer firmwareName: the name of the firmware, e.g. "RepRapFirmware", "Smoothieware" or "Repetier" geometry: one of "cartesian", "delta", "corexy, "corexz" etc. axes: the number of axes volumes: the number of SD card slots available numTools: the number of available tools numbered contiguously starting from 0

The fields may be in any order in the response. Other implementations may omit fields and/or add additional fields.

Though with care and adjustment a RepRap can be set up with its axes at right-angles to each other within the accuracy of the machine, who wants to bother with care and adjustment when the problem can be solved by software? This tells software the tangents of the angles between the axes of the machine obtained by printing then measuring a test part. The S parameter (100 here) is the length of a triangle along each axis in mm. The X, Y and Z figures are the number of millimeters of the short side of the triangle that represents how out of true a pair of axes is. The X figure is the error between X and Y, the Y figure is the error between Y and Z, and the Z figure is the error between X and Z. Positive values indicate that the angle between the axis pair is obtuse, negative acute.

Примеры

Set the points at which the bed will be probed to compensate for its plane being slightly out of horizontal.

The first form defines the points for for G32 bed probing. The P value is the index of the point (indices start at 0) and the X and Y values are the position to move extruder 0 to to probe the bed. An implementation should allow a minimum of three points (P0, P1 and P2). This just records the point coordinates; it does not actually do the probing. See G32. Defining the probe points in this way is deprecated in RepRapFirmware, you should define them in a bed.g file instead.

The second form defines the grid for G29 bed probing. For Cartesian printers, specify minimum and maximum X and Y values to probe and the probing interval. For Delta printers, specify the probing radius. If you define both, the probing area will be the intersection of the rectangular area and the circle. There is a firmware-dependent maximum number of probe points supported, which may be as low as 100.

A Z probe may be a switch, an IR proximity sensor, or some other device. This selects which to use:

P0 indicates that no Z probe is present

P1 indicates an unmodulated IR probe, or any other probe type that emulates an unmodulated IR probe (probe output is an analog signal that rises with decreasing nozzle height above the bed). If there is a control signal to the probe, it is driven high when the probe type is P1

P2 specifies a modulated IR probe, where the modulation is commanded directly by the main board firmware using the control signal to the probe

P3 selects an alternative Z probe similar to P1 but the control signal to the probe low

P4 selects a switch for bed probing (on the Duet, this must be connected to the E0 endstop pins)

P5 (from RepRapFirmware 1.14) selects a switch or a digital output device to the In pin of the Z-probe connector

P6 is as P4 but the switch is connected to and alternative connector (on the Duet series, the E1 endstop connector)

P7 is as P4 but the switch is connected to and alternative connector (on the Duet series, the Z endstop connector)

P8 is as P5 but the signal is unfiltered for faster response

P9 is as P5 but the probe is deployed and retracted at every probe point. This is intended for BLTouch.

M563 P3 D0 H1 S"Chocolate extruder" ; create a named tool using extruder drive 0 and heater 1

Tools are usually (though not necessarily) extruders. The 'P' field specifies the tool number. Tool numbers can have any positive integer value and 0. The 'D' field specifies the drive(s) used by the tool - in the first example drives 0, 2 and 3. Drive 0 is the first drive in the machine after the movement drives (usually X, Y and Z). If there is no 'D' field the tool has no drives. The 'H' field specifies the tool's heaters - in the first example heaters 1 and 3. Heater 0 is usually the hot bed (if any) so the first extruder heater is usually 1. If there is no H field the tool has no heaters.

Tools are driven using multiple values in the 'E' field of G1 commands, each controlling the corresponding drive in the 'D' field above, as follows:

G1 X90.6 Y13.8 E2.24:2.24:15.89 G1 X70.6 E0:0:42.4

The first line moves straight to the point (90.6, 13.8) extruding a total of 2.24mm of filament from both drives 0 and 2 and 15.98mm of filament from drive 3. The second line moves back 20mm in X extruding 42.4mm of filament from drive 3.

Alternatively, if the slicer does not support generating G1 commands with multiple values for the extrusion amount, the M567 command can be used to define a tool mix ratio.

Normally an M563 command is immediately followed by a G10 command to set the tool's offsets and temperatures.

It is permissible for different tools to share some (or all) of their drives and heaters. So, for example, you can define two tools with identical hardware, but that just operate at different temperatures.

The X mapping option is used to create tools on machines with multiple independent X carriages. The additional carriages are set up as axes U, V etc. (see M584) and the X mapping option in M563 defines which carriage or carriages are used.

If you use the M563 command with a P value for a tool that has already been defined, that tool is redefined using the new values you provide.

RepRapFirmware supports an additional form of the M563 command. The command:

M563 S1

means add 1 (the value of the S parameter) to all tool numbers found in the remainder of the current input stream (e.g. the current file if the command is read from a file on the SD card), or until a new M563 command of this form is executed. The purpose of this is to provide compatibility between systems in which tool numbers start at 1, and programs such as slic3r that assume tools are numbered from zero.

Recent versions of RepRapFirmware allow the deletion of existing tools if M563 is called in this way:

Snnn S1 = limit movement within axis boundaries, S0 = allow movement outside boundaries

Например

M564 S0 H0

Allow moves outside the print volume and before homing, or not. If the S parameter is 0, then you can send G codes to drive the RepRap outside its normal working volume, and it will attempt to do so. Likewise if the H parameter is 0 you can move the head or bed along axes that have not been homed. The default behaviour is S1 H1. On some types of printer (e.g. Delta and SCARA), movement before homing is prohibited regardless of the H parameter.

Ennn Maximum instantaneous speed change of the extruder drives

Например

M566 X20 Y20 Z2 E10

Sets the maximum allowable speed change (sometimes called 'jerk speed') of each motor when changing direction.

The model files and gcode files used by repraps generally render circles and other curves shapes as a sequence of straight line segments. If the motors were not allowed any instantaneous speed change, they would have to come to a stop at the junction between each pair of line segments. By allowing a certain amount of instantaneous speed change, printing speed can be maintained when the angle between the two line segments is small enough.

If you set these X and Y values too low, then the printer will be slow at printing curves. If they are too high then the printer may be noisy when cornering and you may suffer ringing and other print artefacts, or even missed steps.

On very old versions of RepRapFirmware (prior to 1.09), these were also the minimum speeds of each axis.

This example sets the mix ratio for tool 2 (the P value). When mixing is then turned on (see M568), only single E values need to be sent on a G1 command (any extra E values will be ignored, but are not illegal):

G1 X20 E1.3

This will move to X=20 extruding a total length of filament of 1.3mm. The first drive of tool 2 will extrude 0.1*1.3mm, the second 0.2*1.3mm and so on. The ratios don't have to add up to 1.0 - the calculation done is as just described. But it is best if they do.

Примечания

All parameters except P are optional. For any parameter that is not provided, the corresponding value will not be changed.

The T parameters are intended for use with external stepper drivers. Currently, RepRapFirmware only remembers the highest T parameters seen in any M569 command, and applies those values to all drivers for which any nonzero T parameters were specified.

The modes (D parameter) supported by various stepper driver chips are:

TMC2130: modes 0,1,2,3

TMC2660: modes 0,1,2

TMC2208/2224: modes 2,3 (mode 3 is stealthChop 2)

Some versions of RepRapFirmware prior to 1.14 also provided X, Y, Z and E parameters to allow the mapping from axes and extruders to stepper driver numbers to be changed. From 1.14 onward, this functionality is provided by M584 instead.

Parameters for RepRapFirmware 1.14 and earlier

Snnn Heater timeout (in seconds)

Например

M570 S120

After a heater has been switched on, wait 120 seconds for it to get close to the set temperature. If it takes longer than this, raise a heater fault.

Parameters for RepRapFirmware 1.15e and later

Hnnn Heater number

Pnnn Time in seconds for which a temperature anomaly must persist on this heater before raising a heater fault (default 5 seconds)

Tnnn Permitted temperature excursion from the setpoint for this heater (default 10C)

Snnn Time in seconds after a heater fault is raised after which the print will be abandoned, default 10 minutes (RepRapFirmware 1.20 and later)

Например

M570 H1 P4 T15

Warning! Heating fault detection is provided to reduce the risk of starting a fire if a dangerous fault occurs, for example if the heater cartridge or thermistor falls out of the heater block. You should not increase the detection time or permitted temperature excursion without good reason, because doing so will reduce the protection.

Pnnn Logical pin number (RepRapFirmware 1.17 and later), defaults to the FAN0 output until M571 with a P parameter has been seen

Например

M571 P3 F200 M571 S0.5

This turns the controlled pin output on whenever extrusion is being done, and turns it off when the extrusion is finished. The output could control a fan or a stirrer or anything else that needs to work just when extrusion is happening. It also can be used to control a laser beam. The S parameter sets the value of the PWM to the output. 0.0 is off; 1.0 is fully on.

In RepRapFirmware 1.17 and later you can use the P parameter to change the pin used and you can also set the PWM frequency. Pin numbers are the same as in the M42 and M280 commands. The pin you specify must not be in use for anything else, so if it is normally used as a heater you must disable the heater first using M307, or if it is used for a fan you must disable the fan using M106 with the I-1 parameter.

Dnnn Extruder number

Snnn Pressure advance amount (in seconds)

Например

M572 D0 S0.1

This sets the pressure advance coefficient (S parameter) for the specified extruder (D parameter). Supported by RepRapFirmware-dc42, -ch and -dn.

Pressure advance causes the extruder drive position to be advanced or retarded during printing moves by an additional amount proportional to the rate of extrusion. At the end of a move when the extrusion rate is decreasing, this may result in the extruder drive moving backwards (i.e. retracting). Therefore, if you enable this feature, you may need to reduce the amount of retraction you use in your slicing program to avoid over-retraction.

With Bowden extruders, an S value between 0.1 and 0.2 usually gives the best print quality.

Older versions of RepRapFirmware used the P parameter to specify the drive number, instead of using D to specify the extruder number.

Например

M574 X1 Y2 Z0 S1  ; X endstop at low end, Y endstop at high end, no Z endstop, all active high

This defines the position of endstop sensor that the printer has for each axis: 0 = none, 1 = low end, 2 = high end. The optional S parameter defines whether the endstop input is active high (S1, the default), low (S0), or the axes listed use the Z probe for homing that axis (S2), or motor stall detection (S3). A normally-closed endstop switch wired in the usual way produces an active high output (S1). If different axes use different types of endstop sensing, you can use more than one M574 command.

On delta printers the XYZ parameters refer to the towers, and the endstops should normally all be high end (i.e. at the top of the towers).

The S2 and S3 options are supported in RepRapFirmware 1.20 and later.

In RepRapFirmware 1.16 and earlier, the M574 command with E parameter was used to specify whether a Z probe connected to the E0 endstop input produces an active high (S1) or active low (S0) output. In RepRapFirmware 1.17 and later, use the I parameter of the M558 command instead.

This is a version of the M700 command used by the Inkshield, but unfortunately M700 is already taken so cannot be used for that in the standard.

Например

M579 X1.0127 Y0.998

On a Cartesian RepRap you can get prints exactly the right size by tweaking the axis steps/mm using the M92 G Code above. But this does not work so easily for Delta and other RepRaps for which there is cross-talk between the axes. This command allows you to adjust the X, Y, and Z axis scales directly. So, if you print a part for which the Y length should be 100mm and measure it and find that it is 100.3mm long then you set Y0.997 (= 100/100.3).

This is not really anything to do with RepRap, but it is convenient. The little Roland mills are very widely available in hackerspaces and maker groups, but annoyingly they don't speak G Codes. As all RepRap firmware includes a G-Code interpreter, it is often easy to add functions to convert G Codes to Roland RML language. M580 selects a Roland device for output if the R field is 1, and returns to native mode if the R field is 0. The optional P string is sent to the Roland if R is 1. It is permissible to call this repeatedly with R set to 1 and different strings in the P field to communicate directly with a Roland.

Tnn Logical trigger number to associate the endstop input(s) with, from zero up to a firmware-specific maximum (e.g. 9 for RepRapFirmware)

X, Y, Z, E Selects endstop input(s) to monitor

P Reserved, may be used in future to allow general I/O pins to cause triggers

S Whether trigger occurs on a rising edge of that input (S1, default), falling edge (S0), or ignores that input (S-1). By default, all triggers ignore all inputs.

C Condition: whether to trigger at any time (C0, default) or only when printing a file from SD card (C1)

Например

M581 E1:2 S1 T2 C1  ; invoke trigger 2 when a rising edge is detected on the E1 or E2 endstop input and a file is being printed from SD card

When M581 is executed, if the T parameter is present but the other parameters are omitted, the trigger inputs and edge polarities for that trigger number are reported. Otherwise, the specified inputs and their polarities are added to the conditions that cause that trigger. Using S-1 with no X, Y, Z or E parameters sets the trigger back to ignoring all inputs.

In RepRapFirmware, trigger number 0 causes an emergency stop as if M112 had been received. Trigger number 1 causes the print to be paused as if M25 had been received. Any trigger number # greater then 1 causes the macro file sys/trigger#.g to be executed. Polling for further trigger conditions is suspended until the trigger macro file has been completed. RepRapFirmware does not wait for all queued moves to be completed before executing the macro, so you may wish to use the M400 command at the start of your macro file. If several triggers are pending, the one with the lowest trigger number takes priority.

T Trigger number to poll

Например

M582 T2 ; check levels of inputs that give rise to trigger #2

Triggers set up by the M581 command are normally activated only when the specified inputs change state. This command provides a way of causing the trigger to be executed if the input is at a certain level. For each of the inputs associated with the trigger, the trigger condition will be checked as if the input had just changed from the opposite state to the current state.

For example, if you use M581 to support an out-of-filament sensor, then M582 allows you to check for out-of-filament just before starting a print.

Pnnn Pin number

Sn State to wait for (0 or 1) or analog tolerance

Rnnn Analog value to wait for (between 0.0 and 1.0)

Например

M583 P5 S0 ; Wait for Pin 5 to become 0

This allows you, for example, to turn on a DC motor (see the M42 command) then wait until a switch connected to Pin Pnnn gives the value Sn.

If the R field is present, then the system waits until the value on analog Pnnn is reached. In this case the S value is used as a tolerance, so M583 P8 R0.7 S0.01 would wait until the analog value on Pin 8 was between 0.69 and 0.71.

Pnnn Number of visible axes, defaults to the total number of axes configured.

M584 X0 Y1 Z2:3 E4:5:6 ; Driver 0 controls the X motor, 1 controls Y, 2 and 3 control Z motors, 4 and 5 control E motors

Assigning a drive using M584 does not remove its old assignment. Therefore, if you assign a drive that defaults to being an extruder drive, you should also assign the extruder drives explicitly as in the above example. Failure to do so may result in unexpected behaviour.

You can use M584 to create additional axes - for example, to represent additional carriages on a machine with multiple independent X carriages. Additional axes must be created in the order UVWABC. You can hide some of the last axes you create using the P parameter. Hidden axes have no homing buttons or jog controls in the user interface.

On the Duet WiFi and Duet Ethernet, if you configure multiple drivers for an axis, either all of them must be TMC2660 drivers on the Duet or a Duet expansion board, or none of them must be. This is to facilitate dynamic microstepping and other features of the TMC2660.

M585: Probe Tool

In machines with a tool probe this probes the currently selected tool against it and corrects the offsets set by the G10 command (q.v.).

Parameter must be only one of

Xnnn

Y-nnn

Znnn

Where the absolute value of nnn is the radius of the tool plus the radius of the probe in that direction. So M585 X1.5 will set the X offset of a 1mm diameter tool against a 2mm diameter probe, etc. If the value of nnn is positive the tool is moved in the positive direction towards the probe until it touches. If it is negative, the tool moves the other way.

So the process should be:

Set the values as closely as known in the G10 command.

Move to a position slightly offset from the probe then execute M585s in X, Y and Z in the tool selection macro to set them precisely.

After this, the G10 command on its own can be used to report the values.

Pnn Protocol: 0 = HTTP or HTTPS, 1 = FTP or SFTP, 2 = Telnet or SSH (which of the two choices depends on the T parameter)

Snn 0 = disable this protocol, 1 = enable this protocol

Rnn TCP port number to use for the specified protocol. Ignored unless S = 1. If this parameter is not provided then the default port for that protocol and TLS setting is used.

Tnn 0 = don't use TLS, 1 = use TLS. Ignored unless S = 1. If this parameter is not provided, then TLS will be used if the firmware supports it and a security certificate has been configured. If T1 is given but the firmware does not support TLS or no certificate is available, then the protocol will not be enabled and an error message will be returned.

M586 with no S parameter reports the current support for the available protocols.

RepRapFirmware 1.18 and later enable only HTTP (or HTTPS if supported) protocol by default. If you wish to enable FTP and/or Telnet, enable them using this command once or twice in config.g.
