Эта страница описывает особенности G-кодов, которые используются в прошивках принтеров RepRap, и как эти коды работают. Основной целью является аддитивное производство с использованием процессов FFF. Коды для движения печатающей головки придерживаются стандарта G-кода NIST RS274NGC, поэтому прошивки RepRap вполне пригодны для фрезерования с ЧПУ и также для аналогичных приложений. 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. Слайсеры - это самый простой способ перейти от 3D-модели к напечатанной детали, однако пользователь жертвует некоторой гибкостью при их использовании. Другой вариант для получения G-кода, является использование библиотеки более низкого уровня, вроде mecode. Библиотеки, такие как mecode, дают вам точный контроль над траекторией инструмента, и, следовательно, полезны, если у вас есть сложная печать, которая не подходит для бесхитростного слайсинга. Последний вариант - просто написать G-код самостоятельно. Это может быть лучшим выбором, если необходимо выполнить несколько тестовых линий при калибровке принтера.

Поскольку существует много различных прошивок и их разработчики, как правило, реализуют новые функции без обсуждения стратегии или не глядя на то, что делали другие до них, на протяжении многих лет разрабатывались различные варианты, специфичные для 3D-печати. Данная 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

Типичный фрагмент G-кода, отправленный на RepRap устройство, может выглядеть следующим образом: 

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 (в большей степени) 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. Подробнее на Start GCode routines и End GCode routines страницах.

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 BFB 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.
{{???}}
Неизвестно, поддерживает ли прошивка этот G-код. 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

RepRap G-код - это список полей, разделенных пробелами или разрывами строк. Поле можно интерпретировать как команду, параметр или для любых других специальных целей. Оно состоит из одной буквы, за которой непосредственно следует число, или может быть только автономной буквой (флагом). Буква дает информацию о значении поля (см. список ниже в этом разделе). Числа могут быть целыми (128) или дробными (12.42), в зависимости от контекста. For example, an X coordinate can take integers (X175) or fractionals (X17.62), but selecting extruder number 2.76 would make no sense. В этом описании числа в полях представлены nnn в качестве заполнителя.

В RepRapFirmware за некоторыми параметрами может следовать более одного числа, причем двоеточие используется для их разделения. 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 Значение
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 Координата X, обычно для перемещения. Это может быть целое или дробное число.
Ynnn Координата Y, обычно для перемещения. Это может быть целое или дробное число.
Znnn Координата Z, обычно для перемещения. Это может быть целое или дробное число.
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 Параметр - используется для температур
Qnnn Параметр - в данный момент не используется
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.

Чувствительность к регистру

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 (за исключением строк 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.

Поддержка FiveD Teacup Sprinter Marlin Repetier Smoothie RepRapFirmware Machinekit BFB MakerBot grbl Redeem MK4duo
Да Да Да Да Да ??? Да Да ??? ??? ??? Да Да
Например
N123

При наличии номер строки должен быть первым полем в строке. Для G-кода, хранящегося в файлах на SD-картах, номер строки обычно опускается.

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. Для G-кода, хранящегося в файлах на SD-картах, контрольная сумма обычно опускается.

Микропрограммное обеспечение сравнивает контрольную сумму с локально вычисленным значением. Если они отличаются, он запрашивает повторную передачу строки.

Микропрограммное обеспечение RepRap проверяет номер строки и контрольную сумму. You can leave both of these out - RepRap will still work, but it won't do checking. Вы должны иметь оба или ни того, ни другого. Если отображается только один, возникает ошибка.

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 и G28-G32. The Teacup Firmware buffers also some setting commands: G20, G21, G90 и 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.

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                 ; Скорость подачи 1500mm/m
G1 X50 Y25.3 E22.4 F3000 ; Ускорение до 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. In RepRapFirmware, G1 is always a linear move but G0 may not be linear (e.g. on a SCARA machine); however a G0 move will never go below the lower of the initial and final Z height of the move.

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.

(sets the offset for tool 2 to the X, Y, and Z values specified) 

G10 P1 R140 S205

(RepRapFirmware only - set standby and active temperatures3 for tool 1)

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. Smoothie uses G10 for retract and G10 Ln for setting workspace coordinates. RepRapFirmware interprets a G10 command with no P or L parameter as a retraction command.

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.

4Tool 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.

5L1 (the default) sets the offsets of the current tool relative to the head reference point to the specified values. L2 sets the current workplace coordinate offsets to the specified values. L20 adjusts the current workplace coordinate offsets so that the current tool head position has the specified coordinates.

Примечания

1In Marlin firmware and Derivatives Mk4duo this is implemented by hard-coded firmware behaviours As defined for variables NOZZLE_CLEAN_STROKES, NOZZLE_CLEAN_START_POINT, NOZZLE_CLEAN_END_POINT and NOZZLE_CLEAN_PARK.

With NOZZLE_CLEAN_PARK enabled, the nozzle will automatically return to the XYZ position after G12 is run.

More on this behaviour is documented inside of the code base.

The use of G12 for tool cleaning clashes with the established use of G12 for circular pocket milling on CNC machines. For this reason, RepRapFirmware does not support G12.

These codes set the current plane as follows:

  • G18 : ZX
  • G19 : YZ

This mode applies to G2/G3 arc moves. Normal arc moves are in the XY plane, and for most applications that's all you need. For CNC routing it can be useful to do small "digging" moves while making cuts, so to keep the G-code compact it uses G2/G3 arcs involving the Z plane.

These commands are supported in Marlin 1.1.4 and later with ARC_SUPPORT and CNC_WORKSPACE_PLANES enabled.

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.

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. Любые заданные координаты игнорируются. 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.

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

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 Значение по умолчанию. 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 Mesh 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

G30 P3 X180 Y180 Z-99999 S-1 ; As previous example but just report the height errors

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 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.

Probe and calculate in Reprapfirmware

RepRapFirmware executes macro file bed.g in response to the G31 command. The bed.g file is typically used to probe the bed and then perform delta calibration if the printer is a delta, or to perform individual leadscrew adjustment to level the bed if the printer has multiple independently-controlled Z motors, or to advise the user on how much to adjust each bed levelling adjustment screw.

Probe and calculate in Repetier firmware

This command probes the bed at 3 or more pre-defined points and implements bed leveling compensation by either moving the A axis during printing (as with regular bed leveling, G29) or by tilting the bed with motors.

Параметры
Snnn Метод выравнивания стола
Pnnn Метод коррекции стола

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. Это по умолчанию.
P1 Моторизованная коррекция. 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.

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.

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. См.также 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 cancel.g if this file is present, if the print is paused and if the axes are homed. Otherwise stop.g is run and the drives are put into idle mode. Also the heaters are turned off if no 'H1' parameter is specified.

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

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

Файлы G-кода:
"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".

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, the times are in seconds, all other values are in mm. 'printTime' is the printing time estimated by the slicer, 'simulationTime' is the time measured when the print was simulated by the firmware. 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.

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.

M37 with no S parameter prints the time taken by the simulation, from the time it was first entered using M37 S1, up to the current point (if simulation mode is still active) or the point that the simulation was ended (if simulation mode is no longer active).

M37 P"filename" enters simulation mode, prints the specified file, exits simulation mode, reports the print time, and appends it to the GCode file as a comment for later retrieval.

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).

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.

3These parameters are only available in MK4duo.

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 достаточно значения 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 прошивке Teacup

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 Marlin, MK4duo, 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)

Параметры: 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 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.

M111 в 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 в Repetier

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

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

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.

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.)

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.

Sets the acceleration that axes can do in units/second^2 for print moves. For consistency with the rest of G Code movement this should be in units/(minute^2), but that gives really silly numbers and one can get lost in all the zeros. So for this we use seconds.

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.

The values specified are added to the endstop position when the axes are referenced. The same can be achieved with a G92 right after homing (G28, G161).

With Marlin firmware, this value can be saved to EEPROM using the M500 command.

A similar command is G10, aligning these two is subject to discussion.

With Marlin 1.0.0 RC2 a negative value for z lifts(!) your printhead.

In builds of RepRapFirmware that support CNC workplace coordinates, using this command is equivalent to using G10 L2 P1 to set the coordinate offsets for workplace 1.

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.

Set servo position absolute.

Параметры
Pnnn Servo index

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.

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.

MK4duo

H[heaters] H = 0-3 Hotend, H = -1 BED, H = -2 CHAMBER, H = -3 COOLER

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?)

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.

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.

Sets Proportional, Integral and Derivative values for bed. RepRapFirmware interprets a negative P term as indicating that bang-bang control should be used instead of PID. In RepRapFirmware, this command is identical to M301 except that the H parameter (heater number) defaults to zero.

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.

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.

The user would typically place the toolhead at the zero point of the axis and issue the M306 command.

This value can be saved to EEPROM using the M500 command (as M206 value).

M307 H1 A346.2 C140 D5.3 B0 S0.8 V23.8 ; set process parameters for heater 1, use PID, and limit heater 1 PWM to 80%

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.

M376: Set bed compensation taper

Нет Нет Нет Нет Нет Да 1.17 и позже Нет Нет ??? ??? ??? Нет
Параметры
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],

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

статус:  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.

This command does a quick stop of all stepper motors and aborts all moves in the planner. This command is only intended for emergency situations, and due to the instant stop the actual stepper positions may be shifted. Note that if `EMERGENCY_PARSER` is disabled, the response may be delayed while the command buffer is being queued. If a print job is in progress, it will continue, so it is important to suspend the print job before using this command.

Нет Нет Нет 2.0 и позже Нет Нет Применяйте M911 Нет Нет ??? ??? ??? Нет

Enable or disable the Power-loss Recovery feature. When this feature is enabled, the state of the current print job (SD card only) will be saved to a file on the SD card. If the machine crashes or a power outage occurs, the firmware will present an option to Resume the interrupted print job. In Marlin 2.0 the POWER_LOSS_RECOVERY option must be enabled.

This feature operates without a power-loss detection circuit by writing to the recovery file periodically (e.g., once per layer), or if a POWER_LOSS_PIN is configured then it will write the recovery info only when a power-loss is detected. The latter option is preferred, since constant writing to the SD card can shorten its life, and the print will be resumed where it was interrupted rather than repeating the last layer. (Future implementations may allow use of the EEPROM or the on-board SD card.)

Usage: M413 S[on|off]

If no 'S' parameter if given, this command reports the current state of Power-loss Recovery.

Примеры
M413 S1 Enable power-loss recovery
M413 S0 Disable power-loss recovery
