16/10 and 3.1Nm 23's will be much better.

Edit: The only exception is if you want to link the screws with timing belt.? Then you'll need the bigger motors but 16/10 could still be used.?
Also don't use 80VPSU with 80V drive. You need a safety net for back EMF so use 75V psu with 80V drives.
My fault I am sure, the x axis will be joined with a timing belt in which case would this still negate the 34 or would the 23 be adequate. but if I can use the 16/10 then thats great!

Noted on the drives voltage that makes sense must be a sunday thing on my part! As ever cheers for the response!
