[Phil Barrett] designed a new CNC controller breakout board called the PicoCNC which uses the Raspberry Pi Pico RP2040 module and grblHAL. It packs a bunch of features typical of these controllers, ...

Paused for the summer is the CNC milling machine project, but an eye is being kept on suitable electronics. My set-up has external stepper motor driver boxes, and so on-board drivers are superfluous.

It seems like every year, it gets a bit easier to build your own CNC. From the Enhanced Machine Controller (EMC) project of the early 1990s to Arduinos running Grbl in the late 2000s, the open source ...
