capacitive sensors PNP (NC) 10-24V for endstops on a Duet Wifi

hmm if the led on the board changes, it should also change with m119.
maybe the level of the signal is not correct, but i can not comment on that.i connected to gnd of the Endstops. Is this correct?
-
you connected the signal to gnd?
the signal should go to the stop pin -

the signal should go to the stop pinno i connected Signal to stop pin and ground of the sensor to ground pin of the Endstop.
but there is also the ground nearby the Vin which I could use.
-
at moment i only connected 1 of the 3 Endstops. Could this be a problem?
-
I measured at stop (signal) pin 0V when closed and 2.95V when opened.

Those values should be fine.
However your description of how the resistors are connected does not match the documentation you linked to.
Perhaps you description is simply incorrect because the documentation is consistent with my tests.
What board are you using?
What firmware is it running?
Thanks.

The diagram is consistent with your description.
It's just different from the suggested circuit in the documentation.
But what matters is the resultant signal levels and they appear to be good if they are measured on the input pin.

what is about config.g? could there something be wrong?

Well only you know what you actually wired.
If the new diagram is correct it IS consistent with the documentation AND makes more sense based on my tests.
But, as mentioned, the signal levels are what matter and they seem fine.
Now back to my questions:
What board are you using and what version of firmware is it running?
Thanks.

duet wifi 1.02 with RRF v3.2

@Gerd said in capacitive sensors PNP (NC) 10-24V for endstops on a Duet Wifi:
duet wifi 1.02 with RRF v3.2
Great. Thanks.
Have you started the Object Model browser plug-in? It would appear as an option in the DWC Settings section.

You may want to do that as it makes it easy to verify what the firmware is seeing on the inputs.

no option, i've to look for this plugin.

Select "Allgemein" and check the PLUGINS there.

My apologies.
I should have mentioned in the upper right of the Object Model browser there is a "Refresh" button that needs to be clicked to be sure that data displayed is correct.
See if that makes a difference in what you are seeing.
