Re: Looking for programmable stepper driver
I have a couple of the Dahnaher (Kollmorgen) Smoothstepper drives. You can find them occasionally on ebay. All of the name brand stepper manufacturers (Vexta, Oriental, Pacific Scientific) make them usually called Indexers, heres one from Compumoter (better snag it or I may):

To buy one new your talking about thousands of dollars, otherwise I dont know of any cheap Chinese type indexer drives, but there may be some. It sounds like a Uno or Rasberry would be the easiest cheap way off doing it, just have them send a pulse train to your stepper driver and program it to handle your simple I/O.
