There are formulas for figuring out force required to accelerate loads, and how much force a leadscrew provides for a given motor size. That should get you in the ballpark. "Buying the largest possible stepper" would be costly, and overkill for most applications. There are so many variables involved, there is no universal answer.
Hack is trying to go a certain speed with certain motors and ballscrews. I just tried to steer him in the right direction.
