The actual pin assignments may vary depending on the specific cable assembly. If you encounter erratic movement or the motor fails to rotate, try swapping the wires of one coil pair (e.g., swap A+ and A- on the driver) to reverse the direction. Swapping between coils (e.g., A with B) will cause the motor to oscillate or fail to rotate, as the electrical commutation sequence will be incorrect.
