are those really 10k and 68k resistors?
the colours dont match the ones i find online -

the wiki says 10k and 68K

i dont know what you are trying to tell me with that picture.
If R2 is 10K, then suitable values of R1 are 30K if the sensor is powered from +12V, and 68K if it is powered from +24V.
nowhere does it mention 56k resistors

I misunderstood, I think you mean the resistor I took is 68K.
Yes I also tested a 68K resistor, same problem. With the 68K I measured 2,95V untriggered.

and triggerd?

a few mV

that should be interpreted as 0 and 1

yes it should, but it didn't

since its high on untriggered you might not need the pull up resistor.
try without the ^

Yes I also tried with the pullup resistor

I'll stop for today.
Thank you for your help and your patience!

If the connection between the two resistors measures one value and the pin measures another value there must be a problem in the connection from the resistors to the pin contact.
Here is how I do this:
-
You could do what I did when I had a proximity sensor, I used a 24v relay module. The sensor would trigger it and I used the relay output.

Interesting.
I would have thought the relay would have introduced an unacceptable delay.

@fcwilt I didn't on mine, since the Z axis not going fast enough to matter.
