Are you driving the motors direct from the DeskCNC boards?????? since
you said you haven't seen them run from any drivers????? The boards
only output 5V pulses (steps and direction signals). If so we have a
novel way of driving motors!!!!

Anyway, what I have seen is motors jerking when moved at slow pulse
rate with half-stepping drivers and much smoother when driven at
higher pulse rates and they are all connected correctly. I think to
see if they are running correctly, all you have to do is to measure
if they are being moved the distance commmanded.
