Ender 3 - BLTouch guide installation

With this guide you are going to loose SD card support, but hey, who cares, use cable.

I couldn't install my BLTouch on Ender 3, watching tutorials on youtube or going to and search on forums. I took all informations and errors that i found online and modified the firmware. This guide is only for people that uses Petsfang with stock hotend and 5015 fan. I downloaded a modular support for ender 3 (you can find it between petsfang files) that had a place on the left of the petsfang.
