My lightburn program is stopping in less than 5 minutes after starting a project. I can’t seem to figure out what to do. I have completed several projects recently without incident. I have a Jtech 7w diode laser attached to a Shapeoko 3 xxl running GRBL. Does anyone have any suggestions?

With my limited experience with the program it’s my understanding is Lightburn uploads the program to the lasers memory. I may be wrong, at least that is what mine does. My first thought is your laser memory is full. Clear it and try again.

do you know where i might find the laser memory

Lightburn finally gave me an error popup that said that it had lost communication with the controller. so I dismantled my entire computer set up and cleaned all of the connections and gave my shop a thorough cleaning. I made a surround to prevent any dust and debris from getting to the computer or a…

Fingers crossed for you. Those things are a pain to fix.
