Just setup my Ortur LM2 20w and went to burn my grid and it disconnected. I have it hooked up to my surface pro 7 and using the USB cable it came with.
I went into preview mode and tried starting the job around where it stopped and it started back up fine, until it disconnected again. I started it back up and it resumed the job, however it resumed a couple millimeters off, see pictures. Why would it do this? The machine is screwed down onto my plywood so it didn’t move. Also, it looks like the diagonal lines are off center as well, which were in the beginning of the job before it disconnected the first time. Why? Also looks like it missed a spot. Not happy, I made a really nice plywood table and now I gotta try to sand it all out a redo.
