When i start a job in lightburn i loose connection after about 2 seconds.
If i run same job through laser grbl it works fine with no broblems.
Do you get any message in Console when this occurs?
Also, can you take a screenshot of Edit->Device Settings?
This is almost certainly going to be a communications issue.
I’d suggest doing a search on this forum for similar symptoms.
Most common issue is just a bad USB cable. Either too long or too poor quality. Swap with a known good high quality USB cable preferably with a ferrite bead. There are plenty of other potential issues as well so a search will help you there.
Thank you I will try and see what happens.
