TinyG G2 Core Interface

This is a simple interface board for a TinyG G2 Core CNC controller for the Arduino DUE. I migrated the Eagle project into Fusion360, but haven't managed to get all of the 3D parts sorted just yet. It's actually a useful little piece of kit, and I've had one driving my CNC router for several years now. See my model at... https://grabcad.com/library/ox-cnc-variant-v-slot-c-beam-hybrid-1 It's visible in the photo just above the E-stop. The project is based on the opensource Synthetos G2 Core (https://github.com/synthetos/g2) and I drive it with the opensource Chilipeppr (http://chilipeppr.com/tinyg). A whole CNC control system for the cost of an Arduino DUE + the interface board (<$20). Note that this particular board supports 4 motor drivers, so 3 or 4 axes depending on the setup of your machine. Also, the Grabcad site won't accept the Eagle .sch and .brd files, but I'll happily upload them if anyone wants and can find me a spot somewhere.
