The first rule of stepper motors is don't disconnect a powered up motor...


Mark thank you. Can you suggest any websites which would inform on such things, basic stepper rules, do's and don'ts, drivers and shields and whatnot. I have a very specific thing I want to build but having a devil of a time finding out info about it. Ie the shields I'm seeing arn't stackable so you're limited to 2 steppers... I'm after 4 (and a bunch of other bits). Where to find some reading material covering projects like this with many bits?

Thank you

Look at the reprap project - the prusa mendel has five steppers driven by an arduino - it does it using some little pololu boards, one per stepper that just need a couple of pins apiece. In the case of the reprap, those daughter boards are attached to the main RAMPS board, but there's no reason you couldn't control them directly from the arduino.

Thank you very much wildbill, I'll do that.

Appreciate the pointers
