Hi All

I wouldn't bet on this "A typical Nema14 motor draws 0.75A and the bigger Nema17 motor draws 1.5A."

MEMA 14 and NEMA 17 indicate the defined size of the faceplate. It does not even indicate how long the motor is, much less the current draw.

"It is perfectly possible for a NEMA 14 to 'out pull' a NEMA 17 or a NEMA 23."

From http://reprap.org/wiki/Stepper_motor

Take a look at these two NEMA 14 stepper motors.
