My disagreement is with your statement "as well as any outer shields of signal wiring etc."


Consult your vendor's literature and follow their instructions. I'm not phsycic and wouldn't assume to know how another person should set up their machine. I wouldn't trust my investment to the assumptions offered on an internet message board. Too many variables.

I'm using steppers, and the wire leads were supplied by the vendor, and NEITHER end of the cable shield is "grounded", or attached to a ground, or provides bonding to either the controller or machine. As per the manufacturer's recommendation and construction.

As far as how I "ground" my machine or controller cabinet, I followed my vendor's instructions on that also.

Just looked at a spare motor cable, and the end that connects via a 5 pin plug to the controller has the shield going to "pin 3-ground". The original cables, installed on the machine by the vendor, do not have that connection made. I'll have to ask someone from AHHA what gives.
