Relevant setting on config.g (global.zprobe_index = 1)
;Setup BLTouch as probe 1. This is to allow probe zero to be free for analogue sensor e.g. simple piezo echo "Setting BLTouch" ; K = probe number P= probe type R=Settle time before probing H=Dive Height F=Probe Speed ; T=Speed between probes A=Max probes at each pont S=Repeat deviation M558 K{global.zprobe_index} P9 C"io2.in" R1 H10 F120 T6000 A5 S-1 ;probe 5 times and average M950 S{global.zprobe_index} C"io2.out" ; This is the mod probe - used for deploy and retract G31 K{global.zprobe_index} P25 ; set trigger threshold M280 P{global.zprobe_index} S160 ; reset any error conditions```
