Introduction
The leveling sensor BLTouch works like a servo and offers advantages over the PINDA sensors. It is comparatively insensitive to temperature, and the same Z offset can usually be used for all sheets. Since no metallic sheet is required, printing can also be carried out on other surfaces (glass, Pertinax etc.). This HowTo describes the installation of the BLTouch on a one-sy board under Klipper / Mainsail.
