Did you also rule out cooling, firmware settings and the software you are using? I have also heard there can be a problem with the data being fed from USB bandwidth. I had the same problem once and it was two things: 1 was the power setting of the motor, it was too low, the potmeter on the stepper driver had to be turned up a bit. But, here comes problem #2, since I am using 2.5amp stepper motors, and my stepper drivers are designed for MAX 2 Amps with good cooling, my stepper drivers would overheat too fast so I had to add a cooling fan that would blow on the aluminum cooling elements. Now it's working flawless.
