As for the travel on the gantry I'll be using the "Hiwin" precision ground screws. Tolerences have to be tight and the rack isn't that precise. Hiwin said i can get away with a single screw with a big motor.

One of the forums here for compatible software packages that uses Galil is Camsoft.
You did not indicate what type of gantry you are designing i.e. router, Plasma or....? and the degree of accuracy.
When you indicated a travel of 16 feet I did not think you would be going with a screw. The vast majority of commercial router & plasma tables I have come across use rack and pinion, if meshing is done correctly they can be very accurate, also precision rack is available.
Also for a gantry weight of 250lbs the inertia will be such that if you require a high feed rate with rapid acceleration you will probabally be in need of some kind of reduction between motor and drive.
