It was working perfect until I turned on the power to the spindle, I shut everthing off and started over, again perfect until I powered up the spindle. I have it set up so Mach can control the spindle but am not using it now (just using the manual control), I will take a close look at that wiring since I did make quite of few changes by adding some relays and wiring, maybe I built in a ground loop, will have to read up on that.
