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.

If you don't have any luck re-arranging your wiring ;
You could purchase a surge suppressor (these are commonly fitted across the switch connections inside the casing of power tools) and when fitted across the mains switching relay contacts it will reduce the noise spike considerably.
Personally I prefer to use an (SSR) solid state relay (which switches at the zero crossing point of the mains waveform) in place of the mechanical counterpart. These are extremely quiet as far as electrical noise is concerned and can, if necessary, be switched from an existing relay.
