Yea, hood ditched the dc motor unfortunate and used servos on everything. I really want to use the dc motor and the stepper motors.

Thanks for the info tho!

I bought a small Connect mill which came with a problematic DC spindle motor, it turned out to be the DC drive causing the problems. Decent DC drives were silly money so I ended up with a new 1hp 3phase compact frame motor and new old stock Siemens drive for about half what I'd been quoted for a DC drive

I've looked it's not going to be cheap going down the Ac vfd route, nothing cheap in ebay anyway. Not ruling it out tho, may just take time to find a cheap setup.

I have made some progress and have found a reasonably priced kb dc controller box.

I think someone on here used a kb board but linked it to the bob. more reading required!
