In the third video, [NewsonsElectronics] explains how they could write the world’s smallest GRBL code to swing this with a single Arduino. Hint: it involves removing unnecessary data from the g ...

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 ...

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 ...

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 ...
