Regards a larger PSU for Geoff then he's only controlling a few relays and the BOB, He'll be lucky if pulling 1A total so he's still got 2.5A spare with 40W 3.5A PSU.

Geoff go with Clive's suggestion the 36W will be fine.
They only use what they need.
60v for the Nema 34's.
36v for the Nema 23's. (Although I now know they could probarbly go on the 60v fine).
24v for BoB spindle, estop, limits.
5v for the BoB pul/dir etc and SSR relays.

It's been added to over time and I'm still learning. In reality I could ditch the 36v as suggested above and also ditch the 5v by using a step down module from the 24v for the needed 5v. Only recently realised they existed lol. I'll wait until they fail and re-jig it all later on. That's why I got the larger than needed 24v supply for when this change occurs.
