@Phaedrux
I think the heater channnel is disabled by the M307 -
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

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 P50So 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 pinIan

I uncomment the command M307, and now
M401 and M402 work.
But I still can't get Bltouch "M280 P3 S120 I1" commands to work -
@Phaedrux
Also the deploy.g should be M280 P0 S10.... -

Try "M280 P0 S120" instead

thank you all
I replaced with P0 in my Bltouch orders and it works.
Thanks again to you 3 -

Are the old files.....deploy.g
M280 P0 S10
retract.g
M280 P0 S90Please check also the homing files.....
