Well it was short lived. Same issue again. There are a few other things i suspect causing the problem i dont believe the machine is setup correct. This is a used machine we took in a few months ago and the build sheet behind the pendent door says its a 10,000 hi/low system however whenever we ran it above 7500 we would get issues where it wouldnt stop the spindle and fault out. We also have a double pulley system and wye delta relays in the rear cabinet with rigid tapping. It seems someone may have changed things over time or the factory sheet is incorrect. i noticed i bumped the spindle overide pot beyond 100% which explains why things started acting up. anyways i should probably look to another post related to these other issues since i suspect it needs to be alleviated before proceeding further.
