A window pop-up said error triggered, and at the bottom of the screen it said: Error on line: 1 - internal error . Then it shutdown Mach3. I rebooted everything and at Mach3 start up the bottom said: Application Watchdog Triggered. I have uninstalled and reinstalled Mach3 but it still does the same thing. I can also manually turn on the spindle by M3 or spindle button, but when turned off, the same error occurs. I have tried debounce settings, but it is still the same. What else can I try?
