Thanks Chaz, I need to do some more study but I have two complete machines and the spindle runs and operates on both now, I assume without knowing for certain that the control probably just provides a run signal to the original spindle drive probably like a 0-10 commonly used on a VFD. Not sure I understand how the encoder plays into that for the lathe to know the spindle location, but it’s good to know that the original spindle motor and controls might be an option. That seems like it could be one of the bigger costs. Thanks Gary
