Hello:
For future reference, can anyone direct me to surplus (or unwanted) source
of big (like NEMA 42) stepper motors (read that as affordable?) Just need 1,
bigger the better.
Les Watts is selling a full set, which is more than I need.
Second question: Anyone have a schematic for a discrete high current driver
for high current bipolar motors (>3A per phase)? This is the limit for
integrated circuit drivers I've seen so far. (LM18245, etc). I need to study
one.
Thanks all.
