Hi @Etrok50
I’m immediately reminded of this thread
However I’d also check you’re not running another software such as GRBL that is trying to communicate with your engraver. Try reseating the cable and check your COM port setting on Devices also. On the laser window it should show as “Ready” rather than “Disconnected”.
Did you change anything 2 days ago? Have you attempted to restart your software, computer and engraver?
You say “all this happened while cutting out a small project” by this do you mean the green light started flashing and the status has not changed?
cheers
