That’s because brushless DC motors require carefully timed signals used in a process called Electronic Speed Control (ESC). [Fileark] built and ESC using an Arduino and has a couple of posts ...

grbl is stepper motor controller firmware for three-axis cnc machines ... that are too powerful for the normal drivers included on grbl Arduino shields (or integrated Arduino+drivers equivalents), and ...

there’s an excellent chance you’ll be using Grbl to get moving. It’s also a pretty safe bet you’d end up running it on some variation of the Arduino sitting in a motor controller breakout ...

The 326P-style microcontroller is fed via a couple of Schottkys from either the USB control/programming mcu domain input, or from 5V derived from the 12 – 36V domain input (called ’36V from here) via ...
