Thank you @Jules! My GF stopped 3 cuts lines short of finishing a batch of earsavers, and orange buttoned me. Thought it was just hot, so I waited a bit, but it never started back up. Tried the usual, off, logout, move to center, etc, stuck on focusing, no movement… did that twice, came and found this thread linked on someone else’s support thread, and it was the cable on the laser head that had come loose!
Gave me a scare, but thanks to this guide I was able to get it up and finish those last few cuts. Yay!
