What firmware and version are you running? Marlin? Have you ever reflashed your firmware? Typically you need to tweak the settings in your firmware to turn some features on. For me I had to edit the firmware out of the box to enable mesh bed leveling logic and to add the BL touch adapter. BL touch is used by the printer to measure the distance from the print head to the plate and it auto adjusts the Z-stop… You absolutely need a solid mount for it because it needs to take as accurate a reading as possible…
