Olaf suggested a different stepper motor driver, but I didn't yet for two reasons:
1. Without knowing the specifications of your stepper motor, I can't say whether or not you can use one of the low-cost stepper motor modules typically used in 3D printers. If your stepper motor needs more than about 1.5A in order to drive it in your application, you will need a much more expensive driver. Is there a label on your stepper motor with a part number that we can look up the data for? How many wires are there coming out of the motor?
2. Whether you use a new stepper driver or not, you will need to generate an accelerating pulse train. So I suggest you start by doing that. Then, if the maximum speed you can get is still not high enough, look into getting a different stepper motor driver.
