# Implemented G Codes
|
|
|
|
## G Codes
|
|
|
|
```
|
|
G0 -> G1
|
|
G1 - Coordinated Movement X Y Z E
|
|
G2 - CW ARC
|
|
G3 - CCW ARC
|
|
G4 - Dwell S[seconds] or P[milliseconds]
|
|
G10 - retract filament according to settings of M207
|
|
G11 - retract recover filament according to settings of M208
|
|
G28 - Home all Axis
|
|
G29 - Detailed Z-Probe, probes the bed at 3 points. You must be at the home position for this to work correctly.
|
|
G30 - Single Z Probe, probes bed at current XY location.
|
|
G31 - Dock Z Probe sled (if enabled)
|
|
G32 - Undock Z Probe sled (if enabled)
|
|
G90 - Use Absolute Coordinates
|
|
G91 - Use Relative Coordinates
|
|
G92 - Set current position to cordinates given
|
|
```
|
|
## M Codes
|
|
```
|
|

|
|
M1 - Same as M0
|
|
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)

|
|
M32 - Select file and start SD print (Can be used _while_ printing from SD card files):
|
|
syntax "M32 /path/filename#", or "M32 S<startpos bytes> !filename#"
|
|
Call gcode file : "M32 P !filename#" and return to caller file after finishing (similar to #include).
|
|
The '#' is necessary when calling from within sd files, as it stops buffer prereading
|
|
M42 - Change pin status via gcode Use M42 Px Sy to set pin x to value y, when omitting Px the onboard led will be used.
|
|

|
|
or use S<seconds> to specify an inactivity timeout, after which the steppers will be disabled. S0 to disable the timeout.
|

# Comments
|
|
|
|
Comments start at a `;` (semicolon) and end with the end of the line:
|
|
|
|
N3 T0*57 ; This is a comment
|
|
N4 G92 E0*67
|
|
; So is this
|
|
N5 G28*22
|
|
|
|
(example taken from the [RepRap wiki](http://reprap.org/wiki/Gcode#Comments))
|
|
|
|
If you need to use a literal `;` somewhere (for example within `M117`), you can escape semicolons with a `\`
|
|
(backslash):
|
|
|
|
M117 Hello \;)
|
|
|
|
`\` can also be used to escape `\` itself, if you need a literal `\` in front of a `;`:
|
|
|
|
M117 backslash: \\;and a comment
|
|
|
|
Please note that hosts should strip any comments before sending GCODE to the printer in order to save bandwidth.
