The boards I made were from a bare PCB that I bought from PMinMO.com. I didn't design them, just nailed them together :lol:

I can't say how they rank amongst the collection of DIY drivers out there but I am more than happy. They're microstepping chopper boards that appear to be well liked.

I recommend this site for its knowledge base, it's a good jumping-off point for learning about drivers.

I briefly thought about using less expensive (hollow) shaft but fully supporting it. But I think if Rockcliff had thought this a good thing to do to reduce costs, they'd have said so... Care to comment on that Nick?!


I'll post pictures of what I've got so far on Monday or so.
