Help to get Bltouch running :(

[RajaaKahel]

Hi all, I'm getting a headache making my Bltouch 3.1 running on my Duetwifi 2. I followed this guide and connected the Bltouch and made the changes according to it, but when I'm testing it's not working properly.
Note: both my Duetwifi2 and Bltouch3.1 are original.
I want to use Bltouch for homming Z and bed probing.

What exactly is happening or not happening?

Please post the results of M122 and M98 P"config.g"

Please post your homeall.g and homez.g files.

Does M401 and M402 work to reploy and retract the pin?

your config has a mix of RRF2 and RRF3 commands.

Assuming you are on RRF3 clean up this section

@phaedrux

Thanks for the reply!
M401 and M402 does nothing. The Bltouch is lighting red. If I send "M280 P0 S10" the prob deploys, if i touch it Bltouch starts blinking and doesn't respond then.
I disabled the lines you mentioned.

I'm making progress, I changed to the following:

; Endstops
M574 X1 S1 P"xstop" ; configure switch-type (e.g. microswitch) endstop for low end on X via pin xstop
M574 Y1 S1 P"ystop" ; configure switch-type (e.g. microswitch) endstop for low end on Y via pin ystop
M574 Z1 S2 ; configure Z-probe endstop for low end on Z

; Z-Probe
M950 S0 C"exp.heater3" ; create servo pin 0 for BLTouch
M558 P9 C"^zprobe.in" H5 F120 T6000 ; set Z probe type to bltouch and the dive height + speeds
G31 P500 X0 Y0 Z0 ; set Z probe trigger value, offset and trigger height
M557 X15:385 Y40:300 S40 ; define mesh grid

And now I'm able to use M401 and M402. When I home Z the sensor trigger and stops the bed. I guess now I should use M401 and M402 manually to deploy and retract before and after each homing and probbing? Or is there an easy way to do that automatically?

[Phaedrux]

You don't need to use M401 and M402 manually. They get used by G30 automatically to reploy and retract the pin.

Your homez should match your homeall for homing the Z axis. Right now it's using an endstop that doesn't exist.

Uncomment all this

And delete the rest in homez

[mikeabuilder]

I wonder about the first lines in both your deployprobe.g and a retractprobe.g files. I'm not sure if the "1" will cause an error that makes the rest of the file get skipped.

[RajaaKahel]

Thanks for the input, the probe is now working without farther changes.
