Vcore3 500^3

Purpose

Configure and document a Vcore3 from RatRig with a Duet 3 6HC. The purpose of this repo is not to have a 1 fit all solution but the solution that works for my use case, I've tryed to provide all the hardware components and their setup, this may not suit your case. If you have a suggestion please consider opening a pull request. In the other hand it may help you setup your printer in a fast way, use at your own risk. Parts of the g code are not mine and were extracted from the ratrig config, duet github repos, etc (references on the links and external sources bellow.

HW Config
