Arduino CNC Shield V3.51 - GRBL v1.1 compatible - Uses Pololu Drivers

Description

Ever wanted to build a small CNC router or CNC milling machine?
Love working with Arduino Micro Controllers?
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.
Features:
GRBL v1.1 compatible. (Open source firmware that runs on an Arduino UNO that turns G-code commands into stepper signals)
Uses removable Pololu A4988 compatible stepper drivers. (A4988, DRV8825 and others) (
Not Included
)
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 A4 and A3)
2 x End stops for each axis (6 in total)
+ one Probe
Coolant enable
output
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 un-assembled kit and needs soldering
.
* * * Jumpers color may vary depending on the available stock.
INCLUDED:
Arduino CNC Shield(PCB) and components.
(Basic soldering skills are needed.)
URL with Assembly Instructions
NOT INCLUDED:
Arduino Uno
1-4 Pololu A4988 compatible stepper drivers
FREQUENTLY ASKED QUESTIONS:
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.
Is it hard to assemble/Solder the board?
Not at all. The components are all through hole components and easy to solder in place.
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.
