I just tried the motor off the 100mA supply & it wouldn't start either polarity, sort of sounded like it was trying but didn't get turning... but it ran both directions off the 3A supply. Assume that the 100mA supply isn't up to starting it... does that sound right?
Many Thanks

The controller that you linked is the one I was going to try ne

Jeremy/ All
a friend & I are embarking on a similar project, using a sewing machine motor & controller as drive - looking at Jeremy's photos, I see you've got a double reduction on the drive, just wondered what your motor speed was originally (ours says 10,000rpm, but unchecked... that's on a list of things todo...) & what max speed you get at the chuck - we were thinking about get
