I'm probably stepping out on a limb because electronics aren't my
strong point, but I don't think a PWM DC motor controller will make a
good DC power supply for step motor drivers.

I think the motor controller varies motor speed by changing time on-
off ratios, and doesn't actually vary voltage output. I expect some
of the real electronics wizards to chime in on this one way or the
other.
