That’s the information I was looking for, yes. You didn’t mention that pop-up before, you just said “I can’t delete files”. COM Surrogate is the Windows process that runs the thumbnail preview tool, so that’s what is holding on to the files for some reason. I’ve seen a couple others with this issue, but I’ve never had the problem myself, and haven’t been able to figure out what causes it. Everything I’ve found online so far suggests this is an issue with Windows itself - I’m still reading to see if I can track down why it’s happening.
Try changing the View in the windows file explorer to “Details” instead of thumbnails, and see if that helps. If it doesn’t, restarting your PC should clear those locks.
You can also do this:
- Press Ctrl + Shift + Esc to start Task Manager
- When Task Manager starts, find the COM Surrogate process and right-click it. Choose End task from the menu.
For the laser not connecting, do this for me:
- Power your laser and connect it to the PC
- Run LightBurn
- Go to Help > Enable Debug Logging
- Right-click the ‘Devices’ button
- Count to 5
- Click the ‘Stop’ button
- Count to 5
- Quit LightBurn
You’ll find a file called LightBurnLog.txt in your Documents folder. Attach that here so I can have a look.
