Hacking and Upgrading Cheap Chinese 3020 and 3040 CNCs

I plan to buy a cheap or even second-hand Chinese 3020 or 3040 CNC mill so I looked around to find a way to improve it with parts I already have like Arduino or some simple electronic upgrades. I found two interesting guides:


Upgrading 3020 (and other models) with Arduino, GRBL and CNC Shield V3




Detailed guide by EricAusome can be found at:

John Lauer hacked his 3040 to run with ChiliPeppr and TinyG.

This post will serve as my knowledge base and will be expanded as I gather more CNC hacks.
