You don't need to drop the voltage to the stepper motors. Use a
resistor in series (ie voltage divider with the coil resistance) . If you
look up any tutorial on stepper motors you'll find that they work
much better (ie have more torque) at higher supply voltages. I
don't have my stepper motor info to hand but if you drive them
with pulses (I think) rather than static or slow DC-like waveforms
you can get rid of the resistors too. But don't quote me on that. I
advise you look on the web for a tutorial, quite a few around
