Ведущие разработчики Марлин в настоящее время EvdZ и bkubicek, многие другие вносят свой вклад в виде патчей. Это прошивка для однопроцессорных плат типа Ардуино. Марлин также работает на платах Ultimaker. Поддерживает печать с карты памяти SD, в том числе и с вложенных папок, имеет упреждающее планирование траекторий. Эта прошивка распространяется по лицензии GNU GPL v3 или (по желанию пользователя) любой более поздней версии. Она основана на прошивке Sprinter , которая была лицензирована под GPL v2.

Текущая версия: beta 1 of v1.0.0:

Сматри Marlin on Github.


Работает на RAMPS 1.4, Ultimaker и Sanguinololu. Возможно работает на Generation_6_Electronics, и других аналогичных платах.

The default baudrate is 250000. This baudrate has less jitter and hence errors than the usual 115200 baud, but is less supported by drivers and host-environments.


Отличия и дополнения от Спринтер

Look-ahead:

Marlin has jerk-type look-ahead. Whithout it, it would brake and re-accelerate at each corner. Lookahead will only decelerate and accelerate to a velocity, so that the change in vectorial velocity magnitude is less than the xy_jerk_velocity. This is only possible, if some future moves are already processed, hence the name. It leads to less over-deposition at corners, especially at flat angles.

Arc support:

Slic3r can find curves that, although broken into segments, were meant to describe an arc. Marlin is able to print those arcs. The advantage is that the firmware can choose the resolution, and can perform the arc with nearly constant velocity, resulting in a nice finish. Also, less serial communication is needed.

Temperature Oversampling:

To reduce noise and make the PID-differential term more useful, 16 ADC conversion results are averaged.

AutoTemp:

If your gcode contains a wide spread of extruder velocities, or you realtime change the building speed, the temperature should be changed accordingly. Usually, higher speed requires higher temperature. This can now be performed by the AutoTemp function. You can enable AutoTemp mode by issuing M109 S T F and suable it by issuing M109 without any F value. When active, the maximal extruder stepper rate of all buffered moves will be calculated, and named "maxerate" [steps/sec]. The desired temperature then will be set to t=tempmin+factor*maxerate, constrained between tempmin and tempmax. If the target temperature is set manually or by gcode to a value less then tempmin, it will be kept without change. Ideally, your gcode can be completely free of temperature controls, apart from a M109 S T F in the start.gcode, and a M109 S0 in the end.gcode.

EEPROM:

If you know your PID values, acceleration, and max-velocities of your unique machine you can set them, then store them in the EEPROM. After each reboot, Marlin will magically load them from EEPROM, independent of what your Configuration.h says.

LCD Menu:

If your hardware supports it, you can build yourself a LCD-CardReader+Click+encoder combination. It will enable you to realtime tune temperatures, accelerations, velocities, flow rates, select and print files from the SD card, preheat, disable the steppers, and do other fancy stuff. One working hardware configuration is documented here: http://www.thingiverse.com/thing:12663 . If you just have a 20x4 or 16x2 display, useful data is shown.

SD card folders:

If you have an SD card reader attached to your controller, folders now work. Listing the files in pronterface will show "/path/subpath/file.g". You can write to file in a subfolder by including the slash-separated path, using lowercase letters in the path. (Also, backup copies of various operating systems are hidden, as well as files not ending with ".g".)

Endstop trigger reporting:

If an endstop is hit while moving towards the endstop, the location at which the firmware thinks the endstop was triggered is output to the serial port. This is useful because the user gets a warning message. Tools like QTMarlin can use this to find acceptable combinations of velocity+acceleration.

Coding paradigm:

Not relevant from a user side, but Marlin was split into thematic chunks, and has tried to partially enforce private variables. This is intended to make it clearer what interacts with what, and leads to a higher level of modularization. We think this is a useful preliminary step for porting this firmware to an ARM platform (for example) in the future. A lot of RAM (with enabled LCD ~2200 bytes) was saved by storing char []="some message" in Program memory. In the serial communication, a #define-based level of abstraction was enforced, so it's clear that some transfer of information (usually beginning with "echo:"), an error "error:", or just normal protocol, necessary for backwards compatibility.

Interrupt based temperature measurements:

An interrupt is used to manage ADC conversions, and enforce checking for critical temperatures. This leads to less blocking in the heater management routine.

Не стандартные M-Коды, Не совпадающие со старой версией Спринтера:

Movement:

  • G2 - CW ARC
  • G3 - CCW ARC

General:

  • M17 - Enable/Power all stepper motors. Compatibility to ReplicatorG.
  • M18 - Disable all stepper motors; same as M84.Compatibility to ReplicatorG.
  • M30 - Print time since last M109 or SD card start to serial
  • M42 - Change pin status via gcode
  • M80 - Turn on Power Supply
  • M81 - Turn off Power Supply
  • M114 - Output current position to serial port
  • M119 - Output Endstop status to serial port

Movement variables:

  • M202 - Set max acceleration in units/s^2 for travel moves (M202 X1000 Y1000) Unused in Marlin!!
  • M203 - Set maximum feedrate that your machine can sustain (M203 X200 Y200 Z300 E10000) in mm/sec
  • M204 - Set default acceleration: 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
  • M220 - set build speed mulitplying S:factor in percent ; aka "realtime tuneing in the gcode". So you can slow down if you have islands in one height-range, and speed up otherwise.
  • M301 - Set PID parameters P I and D
  • M303 - PID autotune, S = target temperature.
  • M400 - Finish all buffered moves.

Advance:

  • M200 - Set filament diameter for advance
  • M205 - advanced settings: minimum travel speed S=while printing T=travel only, B=minimum segment time X= maximum xy jerk, Z=maximum Z jerk

EEPROM:

  • M500 - stores paramters in EEPROM
  • M501 - reads parameters from EEPROM (if you need reset them after you changed them temporarily).
  • M502 - reverts to the default "factory settings". You still need to store them in EEPROM afterwards if you want to.
  • M503 - print the current settings (from memory not from eeprom)

Настройка и компиляция:

Install the arduino software IDE/toolset v22 http://www.arduino.cc/en/Main/Software

For gen6 and sanguinololu the Sanguino directory in the Marlin dir needs to be copied to the arduino environment. copy Marlin\sanguino \hardware\Sanguino

Install Ultimaker's RepG 25 build http://software.ultimaker.com For SD handling and as better substitute (apart from stl manipulation) download the very nice Kliment's printrun/pronterface https://github.com/kliment/Printrun

Copy the Ultimaker Marlin firmware https://github.com/ErikZalm/Marlin/tree/Marlin_v1 (Use the download button)

Start the arduino IDE. Select Tools -> Board -> Arduino Mega 2560 or your microcontroller Select the correct serial port in Tools ->Serial Port Open Marlin.pde

Click the Verify/Compile button

Click the Upload button If all goes well the firmware is uploading

Start Ultimaker's Custom RepG 25 Make sure Show Experimental Profiles is enabled in Preferences Select Sprinter as the Driver

Press the Connect button.
