hi all,
I am one of the unfortunates to have problems with my NM200 V2 mill. I am experiencing intermittent shut downs while machining. Two have been where the spindle and all axis just stop mid program. Fortunately I was machining foam at the time. I had to completely shut down machine and restart computer to reset the machine. I reinstalled Mach 3 version 3.043.022 and now have experienced two inadvertent estops. The e-stops are easier to recover from, the axis still have power but aggravating none the less. After the first e-stop fault a message of "driver watchdog triggered". The machine was only moving at 10in/min, so it was not being overtaxed at time of fault.
I have run Mach 3 on two smaller machines for days at time and never experienced the sudden stops like the NM200.
Another annoying thing is if I turn the coolant pump off/on while the machine is running with the keyboard button the pc screen goes black for few seconds, then comes back on.
Anyone have experience with this? Any suggestions would be helpful.
Thanks,
Bob
