When I built the power drawbar for my X2 I removed all of the electrical boxes from the head and column. I have them sitting on the bench next to the machine.
Since the wiring appeared to be soldered at both the motor and the box, I cut the wires and their protective housing. Now I need to splice in about three feet of extension wire.
The protective housing was flexible plastic over flexible metal. I assumed the metal was for RF shielding for the DC motor, so I've been looking for some kind of metallic braid to put over the extension wires. Then I began to wonder; there's no apparent shielding in the plastic controller box, and I would expect the Xylotex box and steppers would be pretty noisy on their own.
So, is the metal covering on the DC motor wires for RF, or is it simply mechanical protection for the wires?
