In LightBurn, go to Help > Enable Debug Logging (at the bottom), then connect the laser to the computer (or just right-click the ‘Devices’ button if you’re already connected).
Click the Stop button, then quit LightBurn, and email the file called ‘LightBurnLog.txt’ in your Documents folder to support@lightburnsoftware.com with a link to this thread. It’s possible I’m incorrectly ID’ing the controller and outputting commands it doesn’t like.
