Hi All,
I have a new Novakon NM200 that I have experienced two intermittent sudden E-stops and two sudden loss of power to the motors and spindle. The NM200 has a Vista or 7 PC as the OS. I run two other machines on Win XP and never experience this problem. Two Estops had the message "Driver Watchdog triggered". The machine is equipped with limit switches but I do not use them, nor was the table near the switches. Also the motors were not being taxed at all when the E stops occurred (1 during retract, the other machining foam). The two power downs did occurr while machining, the motors and spindle just stopped and I had to power down the pc completely to reset everything. A real pain when machining a 3 hour part.
Novakon suggested uninstalling Mach3 which I did and installing the latest version (3.043.022). But the sudden E-stops started happening.
For now I dissabled the limit switches in pins/ports because I don't really need them, I also unchecked the "enable driver watchdog".
BTW what is "Driver watchdog" and why would I want it? What driver is it watching?
Any other troubleshooting suggestions? ???
Thanks, Bob

Turn OFF the watchdog it is not needed.

Thanks, what is "driver watchdog"? -Bob

The watch dog is an enternal monitor that keeps a watch on things. On some systems it is TOO sensitive and will trip on things that do not effect Mach3 running properly.

Thank you for the reply. Hopefully dissabling the watchdog will help.
