BLTouch doesnt

@DIY-O-Sphere
You mean
M558 P5 C "^ zprobe.in + zprobe.mod" H5 F300 T3000

[DIY-O-Sphere]

@synergy41
Sorry I missed this that is not the trigger height, that is the dive height. That is not the issue...

[DIY-O-Sphere]

@synergy41
M558 P9 C"^zprobe.in+zprobe.mod" H10 F300 T3000 is o.k.
We have to check other things.....

@synergy41
Can you comment "M307 H3 A-1 C-1 D-1" out

[Phaedrux]

What do you have in your deployprobe and retractprobe?

[synergy41]

@DIY-O-Sphere
he tells me this:

[synergy41]

@Phaedrux
deployprobe.g
retractprobe.g

[DIY-O-Sphere]

@Phaedrux
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

See https://duet3d.dozuki.com/Wiki/Connecting_a_Z_probe#Section_Software_setup_RepRapFirmware_Num_3
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

@DIY-O-Sphere
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

[DIY-O-Sphere]

@Phaedrux
Also the deploy.g should be M280 P0 S10....

[DIY-O-Sphere]

@synergy41 said in BLTouch doesnt:

Try "M280 P0 S120" instead

[synergy41]

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 S90

Please check also the homing files.....

thank you
