I recently was completed a burn job, but about 90% of the way through the project, the laser stopped and I saw an error message that prompted me to the lightburn site, explaining that a disconnection with my USB is likely what occurred.
I’m wondering if this has happened to anyone else mid-job, and if it’s possible to start the job where it left off once connection is re-established. I realize this may be unlikely, but it’s worth a shot!
If you are using windows it could be your USB is going to sleep. You need to goto battery settings and then advanced and disallow USB sleeping.
I had this issue every three hours into a burn.
