Overview

The Arduino DUE development platform is ideal for getting started with G2core and for prototyping multi-axis projects. G2core builds for CONFIG=gShield will build firmware and set up pinouts for the DUE supporting 6 Axes, X,Y,Z,A,B and C plus outputs for SpinPWM , all 6 Axis limit switches and a few other I/Os.

A Quick 3 axis solution

Use a gShield on the DUE with 3 on-board 8818 driver devices for 3 Axis operation

External interfaces for full 6 axis operation and more powerful stepper drivers

The diagram below is hosted at https://github.com/cmcgrath5035/G2core-DUE-External-Interfaces. Included are suggested interface devices (proto board, etc) to level shift and buffer the DUE outputs. Consider this a template, there are numerous similar devices that could be used, the MOSFETS are rather inexpensive and easy to work with

Here is a list of external drivers reported to work with the DUE and G2core. These are just examples, not recommendations Feel free to edit this page with your experienced results
