Hi all,

Perhaps someone can elighten me. I remember reading somewhere that the drives would need a resistor (1k I think) to signal ground. Without it, my steppers sound awful and I seem to get a lot of "noise" at the controller. With the resistors, the steppers are nice and quiet and it appears as though so far I am not having electrical noise problems on the controller side.

I am just wondering what is actually happening with the resistors on the signal ground?

Thanks

Chris
