BLtouch 3.1 not working on the Creality Ender 6

Hi all!


A couple of months ago i decided to buy a 3D printer. It is my first one, and i need it for school (I study Industrial Design). Assembling and printing went very smooth, but i decided to add an auto bed leveling sensor: The BLtouch 3.1 from Antlabs.

The assembly went pretty smooth and i installed the latest firmware from the Creality Website. When i start the printer, the BLtouch does a selftest, which succeeds. After that I enter the correct temperature for the nozzle and printing bed for calibration. After that i start measuring (check the video in which i explain it all). But while measuring, the sensor gets stuck and the printer does not respond anymore. The only way is to restart it all.

Can someone please help me? I searched the whole internet, but i could'nt find any solution.
