Well, after reading that, I realize why I had joined the geckodrive Yahoo
group as well. I don't know anywhere near enough about switching to make my
own drivers. I can program a PIC, but then there's still the matter of
getting the signal to the motors in a safe manner. But the Gecko system is
waaaaay out of my budget for the time being. I had my eye on Xylotex for a
cheaper alternative, but I never went ahead.
I for one would be more than happy to buy my drives from you as long as they
are not too expensive. I have 3 unipolar SP57B 24V steppers from COPAL
Electronics, obsolete, can't find specs on Google. I'd love to be able to
recycle those on my machine if possible, especially 'cause they cost me only
$5 each.
All I'd need would be the assembled PCB driver boards, since you appear to
have quite a lot of inventory on hand. :) I can take care of fabricating a
box. I guess I'd start with 3 axis, and get that working first. All I'd
need to know is exactly what input the drivers expect, and I should be able
to feed it something, somehow, someday, from a PIC.
Let me know if you are interested.
Robert
