High signal or Low signal
-
I am attempting to configure filament runout sensors. They are just simple switches. How do I know if they are high signal or low signal when filament is present? Trying to ensure that I am using the correct "P" value following the M591.
Ex: M591 D0 P1 C"xstop" S0 -

You haven't provided any information that could possibly let someone help you identify how your switches are configured.
- How are the wires connected to the Duet?
- How is the switch configured? Normally-open or normally-closed?

I think you are making this way more difficult than it should be. Pick either high or low signal method and see what DWC reports when there is filament (or when there is no filament). If the DWC reports the wrong filament status then reconfigure the software with the opposite method.

@alankilian The two outside wires...Normally closed. BTW, if I knew what information would possibly solve the problem then I would likely know how to solve the problem myself. Thank you for your help.

@jens55 I didn't think of that. I'll make that work. Where can I find that in the DWC? I'm not seeing it.

@jens55 I ran a M122. I have filament in one and no filament in the other. It reports the one with filament as "OK" so I assume I have it configured right. Thank you for your help. You'll have to excuse me, I have a lot of ignorance and doubt but I'm muddling through thanks to people like you who are patient enough to help. Thank you.

@SonnyD1, sorry, I should have mentioned M591 D0, M591 D1 to get the info without having to go through all the output of M122 ... all roads lead to Rome

In the future, when something isn't working, take the time to ask your question and provide everything you know about the system.
Tell the reader what switches you are using, how you have it wired, what tests you have performed and what the results were.
Asking a question and providing the information only you know helps the reader get you a quick answer and possibly a solution to your problem.
If you had said you had a normally-closed switch AND where the wires are connected to on the Duet, it would have been pretty easy to answer your question. Since you didn't say where the wires were connected, it made it impossible to answer your question.
I'm glad you got your system working.

@alankilian Sorry for the confusion. I will work on that in the future. I don't know what information is needed so my hopes is people will ask IOT compensate for my ignorance and to prevent providing unnecessary info. But I will do my best to include more. Thank you.
