Ender 3 pro BLTouch problem

I’m using a MKS Robin E3D v1.1 motherboard in my Ender-3 Pro printer. I want to connect a 3-pin clone to a BLtouch. I’ve connected the motherboard and installed the ready-made BLtouch firmware available on GitHub. However, bed leveling isn’t working properly. We move to the center of the bed, and the axis moves down until the BLtouch is triggered. Then, the screen displays “probing point 1/9.” Then, it moves to the front left corner and stays there. Then, the screen displays “Ready.”

Can anyone who has experienced this or has the same motherboard and connected a bltouch help me?
