So I purchased a BlTouch for my Ender 3 v2. After installing new firmware from creality and setting up the bltouch I pressed autohome and the nozzle kept going down pressing on the plate, so I had to turn it off because it was either going to break my plate or break my nozzle.
Checked all the wires are pressed correctly andthe firmware is for the correct version for my board which is 4.2.2
