|
|
|
|
//Implemented Codes
|
|
//-------------------
|
|
// G0 -> G1
|
|
// G1 - Coordinated Movement X Y Z E
|
|
// G2 - CW ARC
|
|
// G3 - CCW ARC
|
|
// G4 - Dwell S<seconds> or P<milliseconds>
|
|
// G28 - Home all Axis
|
|
// G90 - Use Absolute Coordinates
|
|
// G91 - Use Relative Coordinates
|
|
// G92 - Set current position to cordinates given
|
|
|
|
//RepRap M Codes
|
|
// M104 - Set extruder target temp
|
|
// M105 - Read current temp
|
|
// M106 - Fan on
|
|
// M107 - Fan off
|
|
// M109 - Wait for extruder current temp to reach target temp.
|
|
// M114 - Display current position
|
|
|
|
//Custom M Codes
|
|
// M17 - Enable/Power all stepper motors
|
|
// M18 - Disable all stepper motors; same as M84
|
|
// M20 - List SD card
|
|
// M21 - Init SD card
|
|
// M22 - Release SD card
|
|
// M23 - Select SD file (M23 filename.g)
|
|
// M24 - Start/resume SD print
|
|
// M25 - Pause SD print
|
|
// M26 - Set SD position in bytes (M26 S12345)
|
|
// M27 - Report SD print status
|
|
// M28 - Start SD write (M28 filename.g)
|
|
// M29 - Stop SD write
|
|
// M30 - Output 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
|
|
// M82 - Set E codes absolute (default)
|
|
// M83 - Set E codes relative while in Absolute Coordinates (G90) mode
|
|
// M84 - Disable steppers until next move,
|
|
// or use S<seconds> to specify an inactivity timeout, after which the steppers will be disabled. S0 to disable the timeout.
|
|
// M85 - Set inactivity shutdown timer with parameter S<seconds>. To disable set zero (default)
|
|
// M92 - Set axis_steps_per_unit - same syntax as G92
|
|
// M114 - Output current position to serial port
|
|
// M115 - Capabilities string
|
|
// M119 - Output Endstop status to serial port
|
|
// M140 - Set bed target temp
|
|
// M190 - Wait for bed current temp to reach target temp.
|
|
// M200 - Set filament diameter
|
|
// M201 - Set max acceleration in units/s^2 for print moves (M201 X1000 Y1000)
|
|
// 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
|
|
// M205 - advanced settings: minimum travel speed S=while printing T=travel only, B=minimum segment time X= maximum xy jerk, Z=maximum Z jerk
|
|
// M220 - set speed factor override percentage S:factor in percent
|
|
// M301 - Set PID parameters P I and D
|
|
// M400 - Finish all moves
|
|
// 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.
