I’m having an issue lately with larger pieces. Mach 3 stops and says “not responding” the torch will stay on for a few, but it just stops. It won’t let me click anything in Mach 3 window. The only way to fix is to unplug electronics box. When I replug into the computer Mach 3 responds, but it resets to the beginning.
Happens at random times, could be 30 seconds in or 2 minutes in.
