The link above will allow you to calculate precisely, the highest speed that the motor is capable of (and speeds higher than this will see problems occur). The actual maximum will be limited by physical properties (and contrary to the posts earlier) can be calculated precisley, based on mass measurements and then following it up with basic acceleration calculations (a chap called Issac Newton discovered certain laws that hold true today for the calculation of these properties) based on the torque moment of the stepper and the pulley wheel that drives the belt
