Did you get any response from the Glowforge team? Maybe coincidence but I’m having the same problem at the same time as you. They just told me they think one of the cables connecting to the lid is bad so they’re sending me a new one. I have very little confidence that’s actually the problem, and it definitely doesn’t change the fact that I can’t make anything for one of my biggest craft shows of the year.
Are you still having the issue?
