I just purchased an Atomstack a5 30w laser. When trying to setup my laser with Lightburn it would not automatically find my device. In my research I found that the my laser head should be a GRBL, so I installed it manually. I am guessing it may be incorrect as your software does not fulling understand commands. Also, all the functions of our software are available to me, ex; fonts will not work.
suggests on how to solve my issues.
Also I downloaded the CH 340 driver to connect to my laser, I’m not sure if its the right one?
