If the problem is that your able to turn the handwheel fast enough to exceed the maximum velocity for the axis and build up a store of pulses. Perhaps you should consider limiting the step size generated by the handwheel to one small enough that it is not possible to easily over run the max velocity of the axis. I have seen similar behavior even in large expensive commercial machines with Fanuc controls. Granted you have to turn the wheel really fast, faster than you can sustain for a long enough period to build up a significant overrun but it is detectable.
