  47. // G92 - Set current position to cordinates given
  48. //RepRap M Codes
  49. // M104 - Set extruder target temp
  50. // M105 - Read current temp
  51. // M106 - Fan on
  52. // M107 - Fan off
  53. // M109 - Wait for extruder current temp to reach target temp.
  54. // M114 - Display current position
  55. //Custom M Codes
  56. // M20 - List SD card

  69. // M81 - Turn off Power Supply
  70. // M82 - Set E codes absolute (default)
  71. // M83 - Set E codes relative while in Absolute Coordinates (G90) mode
  72. // M84 - Disable steppers until next move,
  73. // or use S<seconds> to specify an inactivity timeout, after which the steppers will be disabled. S0 to disable the timeout.
  74. // M85 - Set inactivity shutdown timer with parameter S<seconds>. To disable set zero (default)
  75. // M92 - Set axis_steps_per_unit - same syntax as G92
  76. // M115 - Capabilities string
  77. // M140 - Set bed target temp
  78. // M190 - Wait for bed current temp to reach target temp.
  79. // M200 - Set filament diameter
  80. // M201 - Set max acceleration in units/s^2 for print moves (M201 X1000 Y1000)
  81. // M202 - Set max acceleration in units/s^2 for travel moves (M202 X1000 Y1000) Unused in Marlin!!
  82. // M203 - Set maximum feedrate that your machine can sustain (M203 X200 Y200 Z300 E10000) in mm/sec
  83. // 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
  84. // M205 - advanced settings: minimum travel speed S=while printing T=travel only, B=minimum segment time X= maximum xy jerk, Z=maximum Z jerk
  85. // M220 - set speed factor override percentage S:factor in percent
  86. // M301 - Set PID parameters P I and D
  87. // M500 - stores paramters in EEPROM
  88. // M501 - reads parameters from EEPROM (if you need reset them after you changed them temporarily).
  89. // M502 - reverts to the default "factory settings". You still need to store them in EEPROM afterwards if you want to.
