I realize the question is directed at N5QM, but try reducing the drive current instead. As you are finding, increasing the motor drive current will increase the noise. To determine an "adequate" drive level, you can either start at minimum and increase the drive until the motor no longer skips, or start high and decrease the drive until it starts to skip. Then increase the drive current some from that setting in order to provide some margin.

But yeah, if N5QM or anyone else has figured out their digital values for use on RAMBO adjusted this way, go ahead and post them.
