i am trying to connect second BL Touch sensor either main bord or expansion board (Duet 2 Wifi + Duex 5 Expansion), which pin i need to use for zmin for the second sensor. i tried with endstop pins but its not working.

also let me know what to mention in config file, is that i need to create another file for deployprobe and retract probe?
firmware version i am using as RRF3
