NanaG4 I just switched from the skr mini e3 v3.0 to the skr 2. I had the z-probe pin on the mini and i dont know where to connect it on the skr 2. Honestly am new to 3d printing and would be happy to get some help here.
Repetier See https://github.com/bigtreetech/SKR-2/blob/master/Hardware/BIGTREETECH%20SKR%202-Pin.pdf<br/>right bottom you see servos/Pin description. That is where bltouch gets connected. Or if it is just a switch only use the pin. It also shows all other pins and functions/names in case you are unsure. Just use the equivalent to old board.
