Ever wanted to build a small CNC router or CNC milling machine?

Love working with Arduino Micro Controllers?

this is a simple Arduino CNC shield kit (Arduino Extension Board) with the following features:

Latest Arduino CNC Shield Version 3.10
GRBL 0.9 compatible. (Open source firmware that runs on an Arduino UNO that turns G-code commands into stepper signals)
PWM Spindle and direction pins
4-Axis support (X, Y, Z , A-Can duplicate X,Y,Z or do a full 4th axis with custom firmware using pins D12 and D13)
2 x End stops for each axis (6 in total)
Coolant enable
Uses removable Pololu A4988 compatible stepper drivers. (A4988, DRV8825 and others) (Not Included)
Jumpers to set the Micro-Stepping for the stepper drivers. (Some drivers like the DRV8825 can do up to 1/32 micro-stepping )
Compact design.
Stepper Motors can be connected with 4 pin molex connectors or soldered in place.
Runs on 12-36V DC. (At the moment only the Pololu DRV8825 drivers can handle up to 36V so please consider the operation voltage when powering the board.)
Please note that this is an unassembled kit and needs soldering.
* * * Jumpers color may vary depending on the available stock.

Arduino Uno
1-4 Pololu A4988 compatible stepper drivers


What is a CNC router?

What is GRBL? An open source, embedded, high performance g-code-parser and CNC milling controller written in optimized C that runs on an Arduino UNO.

What is Arduino?

What Pololu stepper driver can it use? Pololu A4988 - or Pololu DRV8825 works well.

What projects can this be used for? Small CNC routers, DIY Laser Cutters, 3D Printers and almost any project where you need to control a stepper motors with high precision.
