An interesting Arduino project has been published to the Instructables website showing how an Arduino CNC shield and controller has been used to create an awesome 3 axis Arduino CNC plotter.

That’s where something like this modular CNC controller could really prove to be a game-changer. The idea behind [Barton Dring]’s latest creation started with his port of GRBL to the ESP32.

If you’re building a CNC or laser, there’s an excellent ... of the reasons he decided to port Grbl to the ESP32 board. Price wise the Arduino and ESP32 are around the same, but the ESP does ...

grbl is stepper motor controller firmware for three-axis cnc machines, intended to run on ... for more than a year ond only requires basic Arduino skills. FYI, at least two projects: grblHAL and ...
