A stepper won't work. It needs a completely different driver. In fact I tried to use a stepper in the first iteration because that's what I had at hand but it didn't work well, the movement was to jerkey, the speed to low, it would stall out too easily. It was only a Nema17, so a Nema23 might work better, but still I'd advise against it.
