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 https://github.com/grbl/grbl)
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)
