Wow. I'm not familiar with the Techno interface, but is there a master "start/stop" button or other hardware switch that controls the job? Is it strictly done through their software?
All I can think of is a faulty switch/relay somewhere. A bad/sticky key on the keyboard?
Different situation, but my tablesaw on/off switch once wore out and the saw would occasionally start itself. Needless to say, the motor got unplugged and a new switch installed ASAP.
