I've bought some motors which are bipolar and rated at 4.3 amps. (HN200 3438). Now I'd like to build a simple controller myself, but the only diy controllers I can find don't support over 4 amps. Could I use 2 controllers per motor, hook them up parrallel to both the motor and the interface card? For instance the PICStep, having the 2 boards share one and the same resonator? That would mean designing a new board for it, but that's the easy bit.
Please post your pros and cons to the concept,
