Hello.

Thank you for providing detailed information. That type of stepper motor should be able to be controlled by our drivers. However, without additional cooling, the A4988 can supply a continuous current around 1A, so it might limit the performance of that motor. Instead, I recommend using the DRV8825 stepper motor driver, as it can supply 1.5A without additional cooling.
