BL Touch install issues
I just installed the BL Touch on a CR 10S. My motherboard is a V 2.1. I installed the hardware and software per instructions. When I do an auto home the Y and X axis move to the correct positions ant first. But then the head moves to the center of the board and the Z axis is about 20 to 30 mm above the board. When I do a auto level the Z axis raises up a few mm after each time the plunger on the BL Touch moves in and out.
