Adding BLTouch to Anycubic I3 Mega for ABL Tutorial

BLTouch on Anycubic I3 Mega (Version 2 with ultrabase) - Needs to be 8 bit version

This is designed to work with minimal modification from stock for BLTouch integration into the Anycubic I3 Mega

If you haven't already, I highly suggest you upgrade to TMC2208 drivers. Much much quieter, e.g. link below for 5 of them. You only really need X and Y axis drivers i.e 2, but they're so cheap getting 5 is not a bad idea.
