hello all

I intend to use nema 263 oz stepper motors

Why did you choose that torque? I think these would be better suited to the size of machine you're building, along with at least 60 volt stepper drivers:

All you need now is unlimited time in the shop to get it built and up and running

That's one of the advantages of being at school/university - long summer holidays!
