If you are not familiar with electronics then be very careful when playing with PSUs as mains voltage can kill.
Well that just sucks grrrrrrrrr more money, 'er indoors is gunna neck me. I bought the PSU so I didn't have to hack at the flakey YooCNC controller, looks like I'll be buying another one (PSU) and handing the lot to my son-in-law's cousin who fits alarms/security systems for a living for final wiring then dick around with getting it all to work with Mach.
IMO sellers need to mention these sorts of things in their listings, you can then buy all you need at once. Actually I'm pissed off enough now to email them and stick it up 'em sideways!!

Thanks for the info - if you happen to come across a decent wiring diagram I'd appreciate it, I'm pretty sure I've got the bob/steppers right but would like to double check.
