I'm starting a similar project with a mini x-y table that I had lying around from http://littlemachineshop.com/product...cus=X-Y+Tables. I have some cheap nema 23 unipolar steppers on the way and I need something to control them with. the steppers are 2.2A/phase and run @ 7v. I have been seeing cheap little all in one boards on ebay but nothing quite big enough to supply the current I need for the price I want.
Gecko drives would be an option but seem a little pricey for me right now. Also I could use a lesson on getting them to work with a pc. I assume some sort of breakout board is needed.
Anyone using anything other than a parallel port connection? I would like to use my notebook computer to control it but it has no parallel port on it. No rs232 either for that matter, just usb2, fire wire, ethernet. I guess this is more or less just a bump to Rhodan's question.
