I have a bunch of stepper motors, but no way to run them. looking at controllers online ebay, amazon, etc. most i'm seeing look like need external pulse source. I don't know how to make circuit for that or what frequency is needed. i'd make from controller chip, but has conections to other chips for control I would guess, and no idea how to trigger and think since from printer only work 1 way.
how would I make a pulse source? and ones with all functions seem hard to find. like something for like few A 2-15V.
