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.

After some more frustrating tries I gave up and used some microswitches to complete the printer.
Would the situation with the PNP sensors be better with a Duet 3 board?

So you could not find a combination of resistors that yield the required logic levels?
Did you have the ^ character in the pin name? You definitely would not want that.
While the various sensors I tested needed different values/arrangement of resistors but I was able to get them all working.

@fcwilt Frederick, would you like to test such an igus sensor? I could send you one.

What is a igus sensor?
I will be glad to test it and add it to my list.
