Driving a brushless DC (gimbal) motor can be a pain ... but points out that there are other ways to interface the BLDC motor with the Arduino. A warning is warranted – this is not for the ...

[Frank Herrmann] had an interesting idea to turn a geared DC motor into a ... motor driver’ interface pins hooked up to the motion controller upstream. The Arduino source for this can be found ...

The machine uses a ‘grbl’ controller, which has an Arduino-based circuit that includes multiple outputs, including a powerful 24V pwm signal that is generally used to drive a 60-80W spindle motor.
