In that case I would use 1.5mm but do you really need nema 34 motors if so is your power supply big enough? ..Clive

Thanks Clive, Yeah i need 34 all round as its a heavy gantry with future plans for it to put on a little more weight! This is the setup i had before i stripped my last machine down due to a huge bust up with my last boss. unfortunatly everything else was left :(

I decided to run R&P on the X with cncrouterparts pro drives

Clive would i be right in saying that the 2.5 would be ok to power the spindle? from the spindle to the VFD

2.5mm will be fine I take it that it is a 2.2Kw spindle I personally would use 1.5mm but others might say not. ..Clive

Yeah its the 2.2Kw might aswell bulk it up incase anything changes.

The trouble with 2.5mm is the connecting in to the plug on the spindle and 1.5mm will carry in the region of 18A which is more than enough. Good luck with the build. ..Clive
