I just replaced the black ribbon after encountering the same issue last week. After 3 days, my glowforge stopped working again. I was working on a project and when I pressed start, the laser was shooting, but the head wasn’t moving. I restarted the machine and it was stuck on centering. I’ve cleaned the machine, checked the clips, checked the network and it’s still not working. Im getting quite frustrated because I still have not been able to fulfill all my orders that are due today. I’ve emailed support, but are not as fast as I’d like them to be:(
I see you already emailed us about this and we’re working on it there, so I’m going to close this topic.
