No need to get confuddled it's not rocket science really. The letters will correspond the Ballnut type. You just want standard flanged ballnut.

Nema23 Stepper Motor 3.1Nm

First you'll get a stronger machine if you build it long and narrow rather than wide and short. It would also be easier to join ballscrews with a timing belt and use one motor and have the advantage...
