@sduck The BL Touch should be installed so it activates with the print nozzle approximately 3mm above the bed. If you need 10mm+ offset then check the BL touch is installed at the correct height. Otherwise check that 10mm dialled up = 10mm in distance, if not your z calibration could need setting. I found setting the offset hit & miss and that repeatedly Homing and moving Z to 0mm then tweaking the offset before homing again........ eventually gave me the correct offset.
