G codes

G-Codes

Implemented Codes

• G0 -> G1
• G1 - Coordinated Movement X Y Z E
• G4 - Dwell S or P
• G20 - Units for G0/G1 are inches.
• G21 - Units for G0/G1 are mm.
• G28 - Home all axis or named axis.
• G90 - Use absolute coordinates
• G91 - Use relative coordinates
• G92 - Set current position to cordinates given

RepRap M Codes

• M104 S[targetTemperature] - Set extruder target temp
• M105 - Read current temp
• M106 S[Speed 0..255] - Fan on
• M107 - Fan off
• M109 - Wait for extruder current temp to reach target temp.
• M112 - Emergency stop.
• M114 - Display current position

Custom M Codes

• M80 - Turn on Power Supply
• 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
• 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 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. To disable set zero (default)
• M92 - Set axis_steps_per_unit - same syntax as G92

• M202 - Set max acceleration in units/s^2 for travel moves (M202 X1000 Y1000)
• M203 - Set temperture monitor to Sx
• M204 X[Kp] Y[Ki] Z[Kd] - Set PID parameter. Values are 100*real value!
• M205 - Output EEPROM settings
• M206 - Set EEPROM value
• M231 S[OPS_MODE] X[Min_Distance] Y[Retract] Z[Backslash] F[ReatrctMove] - Set OPS parameter
• M232 - Read and reset max. advance values
