    Hold on think we may be at cross purpose's here or I've miss under stood you.? I wouldn't have recommended those screws and motors at this size.? Longer yes but not at 1200mm.

    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.
