|
|
//Implemented Codes
|
|
//-------------------
|
|
// G0 -> G1
|
|
// G1 - Coordinated Movement X Y Z E
|
|
// 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
|
|
// 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
|
|
// 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)
|
|
// M86 - If Endstop is Not Activated then Abort Print. Specify X and/or Y
|
|
// M92 - Set axis_steps_per_unit - same syntax as G92
|
|
// M115 - Capabilities string
|
|
// M140 - Set bed target temp
|
|
// M190 - Wait for bed current temp to reach target temp.
|
|
// M201 - Set max acceleration in units/s^2 for print moves (M201 X1000 Y1000)
