I have steppers that are being driven with a Xylotex board. It supplies a max of 2.5A per motor. They are 4 wire steppers. From what I've researched it seems that 20AWG wire will suffice. I've also read that I need to use shielded cable for the steppers. My question is what to do with the shield. Does the wire itself simply need to be shielded or should the shield actually be connected in the cabinet, at the motor, or both? If it needs to be connected at either end then I assume I'll need a 5 pin CPC connector instead of 4 so that I can carry the shield through and connect it to a ground somewhere. Any advice?
I'm looking at this cable. Good choice?
