grbl is stepper motor controller firmware for three-axis cnc machines, intended to run on Arduinos with a motor driver add-on board. Engineer in Wonderland cnc-related blogs are indexed here It is the ...

To controller this CNC machine we need a microcontroller board called arduino Nano and we need motor driver IC for each stepper motor that is L293D IC.

Being only ten at the time I was unable to build the thing and, now that I’m 40, I still can’t fathom how to build this DIY CNC plotter out of a DVD player and some Arduino gear.

On the electronic side, he replaced the controller that came with the kit with an STM32F469 discovery board and an Arduino CNC shield.
