Supported G Codes
Smoothie is primarily a G-code interpreter. Here is a list of the G-codes that are currently supported :
| G-Code | Description | Example |
|---|---|---|
| G0 | Move to the given coordinates. To the contrary of G1, if there is a tool it will most of the time be off during this kind of move. This is a "go to" move rather than a "do while going to" move. The F parameter defines speed and is remembered by subsequent commands ( specified in millimetres/minute ) (command is modal) | G0 X10 Y-5 F100 |
| G1 | Move to the given coordinates, see above for difference with G0. Takes the same F parameter as G0. (command is modal) | G1 X20 Y-2.3 F200 |
| G2 | Clockwise circular motion : go to point with coordinates XYZ while rotating around point with relative coordinates IJ (command is not modal) | G2 X10 J5 |
| G3 | Counter-clockwise motion : see above (command is not modal) | G3 Y5 X10 I2 |
| G4 | Dwell S<seconds> or P<milliseconds> | G4 P1000 |
| G10 | Do firmware retract | G10 |
| G11 | Do firmware un-retract | G11 |
| G17 | Select XYZ plane (command is modal) | G17 |
| G18 | Select XZY plane (command is modal) | G18 |
| G19 | Select YZX plane (command is modal) | G19 |
| G20 | Inch mode : passed coordinates will be considered as Inches, so internally translated to millimeters (command is modal) | G20 |
| G21 | Millimeter mode ( default ) : passed coordinates will be considered as millimeters (command is modal) | G21 |
| G30 | Simple Z probe at current XY, reports distance moved down until probe triggers, optional F parameter sets feedrate | G30 - G30 F100 |
| G32 | Uses Z probe to calibrate delta endstops and arm radius, use R parameter to select only arm radius calibration and E to select only endstop calibration. I to set target precision, J to set probe_radius, K to keep current endstop trim settings | G32 - G32 R - G32 E - G32 EK - G32 I0.02 |
| G28 | Home The given axis, or if no axis specified home all axis at the same time (edge) | G28 |
| G90 | Absolute mode ( default ) : passed coordinates will be considered absolute ( relative to 0.0.0 ) (command is modal) | G90 |
| G91 | Relative mode : passed coordinates will be considered relative to the current point (command is modal) | G91 |
| G92 | Set current position to specified coordinates | G92 X0 Y0 Z0 |

| M400 | Wait for the queue to be empty before answering "OK" | M400 |
| M500 | Save some volatile settings to an override file | M500 |
| M501 | load config-override file optionally specifying the extension | M501 - loads config-override, M501 test1 - loads config-override.test1 |
| M502 | Delete the override file, reverting to config settings at next reset | M502 |
| M503 | Display overridden settings if any | M503 |
| M504 | Save the settings to an override file with specified extension | M504 test1 - saves to config-override.test1 edge only |
