The CNC Shield V3.0 allows you to build a engraving machine, 3D printer, mini CNC and other similar devices using your Arduino. It is designed as a shield and can plug on top of an Arduino requiring no external connections and wiring. There are 4 slots on the board for plugging in stepper motor drive module which can drive 1 stepper motor each. Controlling each step stepper motor requires only two IO pins on the Arduino. Just insert this Arduino CNC Shield V3.0 onto an Arduino UNO, and install the GRBL firmware, you can then quickly build a DIY CNC engraving machine.
The extension board can be used for Small CNC routers, Carving Machine, 3D Printers, DIY Laser Cutters, and almost any project where you need to control a stepper motors with high precision
This shield allows you to control upto 4 stepper motors
Controller each stepper motor requires 2 IO Pins only, which saves a lot of IO Pins for other purposes
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)
Supports 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)
WARNING: The Arduino CNC Shield supports power supplies up to 36V. That does not mean that all Stepper drivers can run that high. A4988 drivers are not designed to run at 36V and will blow up the first time you power them up at that voltage. The 36V are for drivers like the DRV8825 that can run on +36V.
