I tried running a print today, and everything seemed to go as usual except I noticed that the glowforge actually didn’t cut/engrave anything. I turned the machine on/off and noticed the button would be purple, then turn off. When I tried to run another print, the button blinks as usual but would not respond.
My button turned purple after the machine stopped engraving mid-way through a 3 hour engraving job. It never worked again. This is something only Glowforge Inc will be able to help you with.
