The Carvera firmware is based on Smoothieware, which support both CNC and 3d printing, we only list Carvera Desktop CNC related codes below, check here for the original code support by Smoothieware.
| Code | Description | Code_Example |

| G0 | Move to the given coordinates. It is used to go to a new area without cutting, it is also called a “rapid” move. Note that the F parameter can be used here and is remembered by subsequent commands | G0 X10 Y5 F100 |
| G1 | Move to the given coordinates, see above for the difference with G0. Takes the same F parameter as G0 | G1 X20 Y2.3 F200 |

The smoothieware supports console commands to operating files, running jobs, monitoring status, etc. The Carvera firmware support most of them too, checkout here. We have integrated them into GUI so you don't need to run manually. The below list are the ones are modified or added by the Carvera.
| Command | Description | Command_Example |
|---|---|---|
| ap |
Enable/disable or change the password for the WiFi Access Point
|
ap xxxx |
| goto |
Resume a job from a certain line.
Be very careful about Z height, and avoid any collisions, you can lift the Z a bit after pausing the job. |
goto xxxx |
| time | Retrieve the current time of the control board, displayed in timestamp format | time |
| version | Retrieve the current firmware version | version |
| wlan |
Connect/disconnect or scan the WiFi network.
|
wlan xxxx |
| 4th Axis |
Check the functionality of the 4th axis module (harmonic drive version) on the Carvera and Carvera Air
|
check_4th |
| beep |
Enable or disable the beep tone played on the Carvera Air
Reset the machine after running these commands for the change to take effect |
config-set sd switch.beep.enable false |
