Elecrow CNC Shield V3.51 for Arduino GRBL v0.9 Compatible with PWM Spind Board DIY CNC Projects Uses Pololu Drivers


Ever wanted to build a small CNC router or CNC milling machine? Love working with Arduino Micro Controllers?

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.

At Protoneer we designed this simple Arduino CNC shield kit (Arduino Extension Board) with the following features:

New with Version 3.51:

Added circuitry for End-Stop and Probe signal filtering. This eliminates false triggers and makes it possible use non-shielded cable for end-stops/probes.

Bigger Solder pads making it easier to assemble.

Probe pin labels have been updated to make it easier to install a probe.


Includes Noise Filers on all endstops and the probing pin.(New in V3.51)

GRBL 0.9 compatible. (Open source firmware that runs on an Arduino UNO that turns G-code commands into stepper signals

4-Axis support (X, Y, Z , A-Can duplicate X,Y,Z or do a full 4th axis with custom firmware using pins A4 and A3)

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.)
