Overview
CNC Router is an open-source printed circuit board by diaxxu, from the diaxxu/CNC-Router repository on GitHub, published under the MIT licence. It is a 2-layer board of 115.4 × 66.5 mm with 34 parts on 50 nets, routed with 302 tracks and 29 vias.
It is built around the ESP32-C3-DEVKITM-1 and IRLZ44N. Its parts include 16 connectors, 5 capacitors, 1 resistor, 1 IC and 1 diode. It belongs with the robots and motor control boards and the ESP32 and RISC-V boards of this library.
Main components
2README
README.mdCNC-Router
This is my homemade modular CNC machine, built from simple available parts. I designed everything in Fusion 360, researched every component, and chose them carefully. It’s not perfect, but it’s beautiful, and I genuinely enjoyed building it.
Why I Made This
To get more hands on experience ? this is a very cool project. A CNC that can carve wood and maybe on a good day cut aluminum, isn't that great ?

Firmware Installation
1- assemble your driver board ( put the driver in plane ) Insert it into the Arduino Uno header
2- connect the arduino uno your pc
3- download grbl.zip from the github
4- upload the code
5- install Universal Gcode sender
6- learn CAM software or use Easel
7- enjoy the results

Questions
How big is the CNC Router PCB?
It measures 115.4 × 66.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the CNC Router use?
34 parts, built around the ESP32-C3-DEVKITM-1 and IRLZ44N. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the CNC Router KiCad files?
From the diaxxu/CNC-Router repository on GitHub, at the commit this page was made from: the board is kicad/cnc router.kicad_pcb and its schematic kicad/cnc router.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the CNC Router design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
