    The motor location is a no-brainer to me. Machine the gantry side to accept motor with a slot for adjustment and lengthen ball screw so goes thru side then put the belt on outside of gantry out the way from chips etc and put a cover over. Simple and neat.

    Pulley size is little small but nothing to do with teeth but because you won't have enough Boss left after machining for grub screws. This will then mean putting grub screws thru the teeth which isn't ideal.
    I find 20 teeth gives good balance leaving enough boss for M5 grub screws. Certainly no less than 18T.
