I did send the seller an email a while back asking if I needed a PSU or how to wire the spindle up to that M542/bob setup and their response was 'sorry we don't know of spindles'. That's the only problem with buying off eBay, 90% of the sellers are just resellers with no idea and when you put them and people like me who are totally new to all this it gets to be a major headache!!

Just on the spindle proper, if memory serves, it's connected to the spindle/power control board and the only power in says 36v and 18v with a 24v connection out to the YooCNC - stuffed if I know to be honest.
