Here is a little test video, for information, I plugged the X's sensor into the Zprobe connector for testing and it works fine.

I still have to install the Zprobe sensor as soon as I receive it.

Good day

@owend

A very big thank you to you for taking the time to help me. It's really awesome.
The M582 is indeed an initialization of the trigger compared to the received signals, it works perfectly
Here are my command lines if anyone ever needs them:

; Led Capteur Nivellement GPIO 2

M950 J0 C"!^duex.gp1"            ; Duplication signal Capteur Z GPIO 1
M950 P0 C"duex.gp2"              ; Sortie GPIO 2 Allumage Indicateur Led
M581 T3 P"duex.gp1" S1           ; Activation fichier trigger3.g
M582 T3                          ; Initialise Trigger 3
M581 T4 P"duex.gp1" S0           ; Activation fichier trigger4.g
M582 T4                          ; Initialise Trigger 4

Trigger 3 :

M42 P0 S1

Trigger 4 :

M42 P0 S0

@owend

I managed to use double the signal from zprobe.in on input GP1 and assigned the output to GP2 as follows :

; Led Capteur Nivellement GPIO 2

M950 J0 C"duex.gp1"              ; Duplication signal Capteur Z GPIO 1
M950 P0 C"duex.gp2"              ; Sortie GPIO 2 Allumage Indicateur Led
M581 T3 P"duex.gp1" S1           ; Activation fichier trigger3.g
M581 T4 P"duex.gp1" S0           ; Activation fichier trigger4.g

trigger3.g

M42 P0 S0

trigger4.g

M42 P0 S1

it works well, but when starting the card, the output is always active until the first switchover of the contact, is there a command to initialize the output to 0 or force the output to update?

@owend
unfortunately, I tried with / without P but nothing worked, the signal is not interpreted unlike the X or Y sensor.

In fact I just wanted the led for the Z sensor (zprobe.in), the other X and Y sensors were used to verify that the operation was possible, and I know that it is doable.
On the other hand I still do not understand why the signal of "zprobe.in" is not interpreted

Thank you very much for your help.
I am also looking on my side, but there is little information on the use that I want to make.

Maybe I could duplicate the signal from my Zprobe sensor by plugging the signal output into a GPIO input in addition to the zprobe.in?

@owend

Thank you very much,

there is a lot of progress with this:

M950 P0 C "duex.gp1"
M581 T3 X Y Z S1
M581 T4 X Y Z S0

trigger3.g

M42 P0 S0

trigger4.g

M42 P0 S1

The led activates well when the X or Y sensors are activated, but for the Z it does not work, there must be a small modification to make

My Z sensor is configured as follows:

M574 Z0 P "nil"
M558 P5 C "zprobe.in" H50 F120 T10000 A5 S0.01

My firmware configuration is as follows:
Circuit: Duet 2 WiFi (2WiFi)
Firmware: RepRapFirmware for Duet 2 WiFi / Ethernet 3.2 (2021-01-05)
Duet WiFi Server Version: 1.23

I tried to replace in the M581 the Z by

"zprobe.in"

but it has no effect

hello everyone, i have my 3d printer project going well.
I am under RRF3 with a duet 2 wifi + duex5 and I would like to use a GPIO output to activate an LED indicator when detecting an endstop X, Y or zprobe.in sensor

For the wiring, no problem, but for the configuration I'm struggling.

I declared the GP1 output as follows:
M950 P0 C "duex.gp1"

But then I block
I am thinking of using M581 P "xstop+ystop+zprobe.in" T "duex.gp1" S1 R0
but it does not work.

Do you have any advice to give me.

Thank you, and have a good day
