BLTouch doesnt
-
Good morning all,
Since I installed the update "RepRapFirmware for Duet 2 WiFi / Ethernet 3.01-RC6 (2020-04-03b3)", I can no longer operate my Bltouch.
however this one is well to feed it lights up in red, and no error on Z-Probe which is well at 0.
My Bltouch work well before the update,
I am attaching my current config file.
" new file " config .gAs well as my old config file which works fine.
" Old file " config.g
Thank you for your help. -

Does the probe deploy and retract by sending M401 and M402? -

No it shows me this: -

The H10 was the trigger height of the probe.
You mean I have to replace P9 with P5? -
@synergy41
The trigger height is set by G31 -
@DIY-O-Sphere
I just tried removing H10 and replacing P9 with P5, but nothing changes -
@synergy41
Also remove the "M280 P0 S10" from the config.g that would trigger the probe.
Maybe you have set it for testing.... -

You mean
M558 P5 C "^ zprobe.in + zprobe.mod" H5 F300 T3000 -
@synergy41
Sorry I missed this that is not the trigger height, that is the dive height. That is not the issue... -
@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 -
What do you have in your deployprobe and retractprobe?

@DIY-O-Sphere
he tells me this:

@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
