You have the Motion planner and the accelleration and velocity settings that are a trap curve and that is it. IF you plan to wind it up on a drum then you also have variable diameter as the cable winds onto the drum. Without positive engagement you can have cable slippage on the sheave.
Steppers are NOT known for their high speed. They are low speed motors. Low resolution to gain speed can drive you into the cogging problem and step loss when driving them beyond their torque curve.
Servos have a much wider operational rpm band.
I think you may want to take a look at a good VFD and motor drive setup.
How fast and what accelleration rates are you talking about ?
What is the accuracy needed for the stop points ?
