If you have a diode laser engraver which is all set up in Lightburn and the laser head moves but it does not engrave or cut, it is more than likely a wrong setting in the Lightburn software. This happened to my laser engraver and I could not figure out why the laser engraver was moving but not burning or cutting.
It took me hours to figure out it was this simple setting in Lightburn which I show you how to change in the video to get your laser engraver to engrave and cut.
