      I think your mappings look fine.

      Can you send m98 p"config.g" to check for any syntax errors?

      Also check your wiring for continuity.

      You could also try simplifying and just map a single motor and endatop and test that first

        m98 p"config.g" gives a green result.

        1. I recall there used to be led lights on duet 2 WiFi, are there lights on duet 3, do you know?
        2. I checked for continuity by testing each endstop individually. Each send stop works fine, it shows correct continuity when i engage it. Like i said it was working for with duet 2 WiFi.
        3. In the status i see a generic message about x end stop, not about x1, x2 endstop. Is there a way to split it?
        4. I'll try doing one end stop at a time like you said and report back.

          What does a green result mean? Can you copy and paste the result?

            It just shows up as green, is it supposed to say something more?

              Yeah there should be a reply like

              12/10/2020, 11:52:26 PM	M98 P"config.g"
              HTTP is enabled on port 80
              FTP is enabled on port 21
              TELNET is disabled
              Warning: Heater 0 appears to be over-powered. If left on at full power, its temperature is predicted to reach 365C
              Warning: Heater 1 appears to be over-powered. If left on at full power, its temperature is predicted to reach 463C
              

              And if there are any syntax errors in config.g they would show there as well.

              It looks like you're sending it on mobile, can you use the full web interface and send it from the gcode console window?

              Send M122 while you're at it for good measure.

                My endstops are in normally closed and they go in NO when they are triggered.

                Sorry about the ! suggestions before. I got caught on the NO part and glossed on the normally closed part. I'll blame that I was on my phone at the time.

                The fact that M119 isn't showing a status change makes me think the wiring isn't making a connection.

                  I just tried the same from my macbook and also my windows computer, both gave out exact same output. Just a green message back like the mobile output was. Below is the output for M122:

                    Ok how bout just sending the M574 command in the console by itself. If there's something wrong with it, it should complain.

                      That's exactly what i thought. So i checked each wire again (even before this message). I will do a more thorough test again, most likely tomorrow. I mean if one endstop wire was loose it would make sense, how come all four of them are reporting it incorrectly, right? (that too after me checking each one of them for continuity). Is it possible that it is the beta firmware?

                        I just did that, I got a green message back for that as well.

                          Are you clicking both endstops when you check M119 or just one?

                            I tried it both ways, but let me double check and try it again. Please gimme 2 minutes, i will run to garage and do this test and report back.

                              It would also be good to do the more basic setup of single axis and single endstop just to confirm things are working and then add the complexity.

                              There's also the SBC and Beta being added into the mix.

                              It might also be worthwhile to temporarily switch over to standalone mode to rule out the SBC being the issue. That would involve getting a new SD card and setting it up with the folder structure for the duet and copying your config files over to the /sys folder. Put the SD card into the duet, disconnect the SBC, plug the ethernet into the duet.

                              If that still doesn't work, could then upload the 3.1.1 firmware zip file to quickly check if it's a beta firmware issue.

                              Those are some things to check. For now though I must sleep.

                                Here are the two results.

                                First one is with both end stops depressed. Second one is with both released.

                                    We're not crazy right? You have them wired correctly in your screen shot?

                                    Duet 3: connect the switch between the IN and GND pins of your chosen IO_x connector.

                                      That's absolutely correct. Only thing I can think of is the final white JST connector that is inserted into the duet may not be connecting properly?

                                      I pulled them all out and will wire using individual ones and plug them in using more reliable black ones.20201211_002606.jpg

                                        Those white connectors that came with official duet 3 were not making contact with the endstop pins, i removed them and replaced them with black dupont pins.

                                          Ok good, glad we're not crazy.

                                          Did the crimp get a bit too crushed maybe? Or maybe the 5 pin connector just needs most of the wire spots populated to get enough pressure on the connector?

                                            I think i will attribute it to my user error. I have never crimped those white ones (JST? right?). But for some reason I could test continuity in them from the housing, they were not connecting to the pin when they were inserted in.

                                            I am glad that we are not crazy, for sure for sure!
