Try setting the acceleration extremely low in your .ini file, and then do jog moves at high speed. If you hear it buzzing loudly at some speed as it accels and decels, you have a resonance issue. You can either get a microstepping drive or add electrical or mechanical damping to the system.
If you don't have much buzzing, then it may be a problem with step and direction timing. One of the most common is that the step pulse polarity is wrong, and therefore the direction signal is changing at the wrong time, and the drive is not sure which way it is supposed to go. Reverse the polarity of the step pulse and see if it fixes it.
