I don't know what pin #8 of the VFD outlet on the C32 is connected to. Somewhow, I suspect that is the culprit that is tripping all of my axis's. Only reason I am coming here is because getting a hold of Arturo is close to impossible. It would be nice if he could asnwer that ?. That definately was the wire. because when I unhooked my drive power supply and rewired that pin to the DC common on my VFD the spindle ran like a charm.
