I have some used steppers with a cylindrical ferrite on the cable. I need to extend the wiring and I wondered which end to put the ferrite on. Should it go near the stepper or near the driver for best noise improvement? And while I'm at it how much does twisting the pairs of wires for each coil help? I assume you would generally do one or the other but not both as it seems like twisted pairs would tend to cancel the effectiveness of a ferrite cylinder around the wires.
