Your Grbl may not support Variable Power mode (M4)

If your laser does not turn off between cuts,

switch to the GRBL-M3 device

Homing

Assuming you have end stop switches, try changing $22=0 to $22=1 If you don’t then disable Homing in Lightburn.

Also see you have what appears to be noise on your USB line you might make sure you have good cable and it’s isolated as much as possible from other potential environment noise being induced into the USB.

You have automatic homing on startup enabled in LightBurn. If your laser doesn’t have homing switches, you’ll need to turn that off. Click the ‘Devices’ button, then double click your laser, click ‘Next’ until you get to the page that has the switch for ‘Auto Home on Startup’ and turn that off. Click Next / Finish when done.

Turns out there was a problem with the power cord.

Well, that could explain a lot. :slight_smile:
