My cnc router has been working well until today. I was trying to get a job running with Chilipeppr no luck. I noticed that the pwm led was on. I hit reset in Chilipeppr, no go so then I pressed the reset button & it still doesn’t complete the normal reset. pwm comes on & stays on. This is a desperate call, as it’s probably died. I’m not using pwm, Has anybody struck this?
