The Ortur machine, if powered, acts as though it is connected, even when the USB isn’t active - they don’t reset the controller when the USB connects like most other systems do, so you have to power cycle the Ortur itself.
Hi, I also opened a ticket with Ortur, they said they are getting a lot of calls on this issue and suggested that I ground the machine, so I made a ground wire and connected to a ground and my Ortur Laser Master 2 frame. So far it is working I have done three 20 minute images without any issues. Still testing. Grounding the machine seems to resolve the issues. I will try engraving some longer jobs and let you know.

I’ve heard similar from a couple different users - one said he was getting static buildup from the X axis belt moving back & forth badly enough that when it discharged it made a visible arc and rebooted his PC. It would be nice if it turned out to be this simple to fix.
