I got Mainboard V4.2.7 and installed it in my Ender 3 and I bought BL touch v3.1 smart. I flashed firmware from creality and all the options for BL touch are a available but when I auto home it goes to corner then to middle of the bed and gives the error to high. The self test works and it will do bed leveling from the BL touch menu. I can’t figure why it’s not working.
