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 Martyn

I also found a wall socket 24v adaptor, only 100mA, but it did the same pulsing inching thing... I reckon maybe when I connected the PCB originally I had something wrong & "fried" something... The controller that you linked is the one I was going to try ne

Hi Roger In respect of your advice in this thread: I followed the links in the above thread to the DC motor & controller, not sure if it's because I'm in the uk but I couldn't find the exact ones that you linked to. I ended up with the following: Motor Controller I used a 24v laptop adaptor to power it all up, but all I get I see the motor "inching" round

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
