Issue with laser losing connection while burning

Hey everybody. New to the world of laser engraving. Just got laser, got everything set up as instructed. Since new, looked to some videos to get started. Got my image ready, hit start. I get 2 lines and the computer and laser disconnect from one another. Used practice file, came with laser. Could really use some help.

Loosing connection is one of the problems all of us have when using usb.

  1. ensure OS isn’t allowing the usb to time out
  2. try a new usb cable

These are the most common issues. It’s very unlikely that the problem is Lightburn.

Good luck


Didnt think it was software. Cable was on my mind even though new. Will check usb. Thank you.
