Hi Mariss,

Thanks for the info. I'll probably start with that 3% sacrifice.
Makes life easier. But being the greedy person I am, I'll also
probably try to get that extra 3% later, so I'll try to digest the
above.

When you say pair the windings, do you mean of the 4 wires of one
phase (say - a, b, c, d) I short a pair of them ( say connect a-b
then c-d) and if they are the right pair, then twirling the shaft
will present no or less resistance when NOTHING is connected?

(Detent torque = that little resistance you feel when trying to turn
the stepper when nothing is connected?)
