If the steppers are vibrating and not moving when you tell them to move... Usually the power to them is too low or you are telling them to move too fast.
Most boards let you control how much power is applied to the steppers. If yours has that... Crank it up. But the other thing you can do is bump the feed rate down and see if they start moving like you expect.
