Hello All. Having latched onto the Arduino a few months back, I am in the process of building a coil winder. I'm using 42V steppers (5 wire unipolar) from a couple of Epson printers. I'm gonna use mosfets opto-isolated to the Arduino. Besides the mosfets I want to order flyback diodes. I read 5 ohms accross individual coils of the stepper. Is a shottky with a 100v, 5a rating overkill? Thanks - Scotty
