I installed a BL Touch to my ender 3 v1 with a 4.2.2 board. The only file I could get to work Firmware wise was a V1.1.2. I see the BL Touch in the options but when I auto home and try to lower the Z axis (it's way too high) it will not lower only raise up. Do I have the correct firmware or is there something I am missing?
