Can you comment "M307 H3 A-1 C-1 D-1" out

Phaedrux

What do you have in your deployprobe and retractprobe?

I think the heater channnel is disabled by the M307

Phaedrux

Was this generated by the configurator or did you create it?

M950 P3 S90 I1

It should be M280 not M950

Your Old config:

; Z-Probe
M307 H3 A-1 C-1 D-1                                ; Disable heater on PWM channel for BLTouch
M558 P9 H10 F300 T3000                             ; Set Z probe type to bltouch and the dive height + speeds
G31 P500 X0 Y25 Z2.45                              ; Set Z probe trigger value, offset and trigger height 2.235 ; 2.40
M557 R140 S25                                      ; Define mesh grid

Your New config

Z-Probe
M307 H3 A-1 C-1 D-1                                ; Disable heater on PWM channel for BLTouch
M558 P9 C"^zprobe.in+zprobe.mod" H10 F300 T3000    ; P9 ESSAI M558 Set Z probe type to bltouch and the dive height + speeds M558 P9 C"zprobe.in+zprobe.mod" H10 F300 T3000 
M950 S0 C"exp.heater3"                             ; ESSAI create servo pin 0 for BLTouch M950 S0 C"exp.heater3"   
M280 P0 S10                                        ; envoyer le signal de contrôle à BLTouch via servo / gpio 0
G31 P500 X0 Y25 Z2.45                              ; Set Z probe trigger value, offset and trigger height 2.235 ; 2.40
M557 R140 S25                                      ; Define mesh grid

M558 should be set with P9. You don't need '+zprobe.mod'. You don't need to disable PWM channel with M307.
If probing is too fast, F60 (which is the speed of probing) is a good place to start. Turn of heaters during probing (reduce magnetic interference) with B1. Also a good idea to set probe recovery time of R1. You can also decrease the trigger value in G31 to improve sensitivity, eg P50

So change to:

M558 P9 C"^zprobe.in" H10 F300 T3000    ; P9 ESSAI M558 Set Z probe type to bltouch and the dive height + speeds
M950 S0 C"exp.heater3"                             ; ESSAI create servo pin 0 for BLTouch M950 S0 C"exp.heater3"   
G31 P50 X0 Y25 Z2.45                              ; Set Z probe trigger value, offset and trigger height 2.235 ; 2.40
M557 R140 S25                                      ; Define mesh grid

To extend and retract probe, see https://duet3d.dozuki.com/Wiki/Connecting_a_Z_probe?revisionid=HEAD#Section_Commissioning_Testing_RepRapFirmware_Num_3. You should use:
M280 P0 S10 ; extend pin
M280 P0 S90 ; retract pin
