About the CNC-Router PCB

CNC-Router is an open source ESP32 PCB design by diaxxu, published on GitHub under the MIT license. It is a 2-layer board measuring 115.4 × 66.6 mm, with 28 components from 11 distinct parts.

Its main chip is the ESP32-C3-DevKitM-1, from the ESP32 family. Other key parts include the Pololu_Breakout_DRV8825. By type, the board carries 15 connectors, 5 capacitors, 3 modules, 1 IC, 1 transistor and 1 diode.

It belongs with the robotics & motion designs in this gallery.

From the project

a challenge i gave myself to make something great ! yes its a cnc milling / laser / plotter machine

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.

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 ?

CNC-Router: common questions

What microcontroller does the CNC-Router use?

The CNC-Router is built around the ESP32-C3-DevKitM-1, from the ESP32 family.

How big is the CNC-Router PCB?

The CNC-Router measures 115.4 × 66.6 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the CNC-Router?

28 components, from 11 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the CNC-Router design files?

From the diaxxu/CNC-Router repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the CNC-Router design in my own project?

Yes, under the terms of its MIT license, which diaxxu chose for the repository.

Can I test firmware for the CNC-Router without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP32 firmware against it before you order a PCB.
