      @Dizzwold It takes a while for G32 to complete so it is completely normal that the "Send Code" button goes into "busy" state as long as it is running (which typically takes some time). Please post your bed.g as well.

      PS: If you get a temperature of 2000C, that probably means you've got an intermittent connection in your wiring somewhere between Duet and thermistor.

        Hi Guy's,

        Thank you both for taking a look.

          I'm still have the problem where every time I home all, G32 followed by G29, I get a network error and the bed compensation runs at least twice.
          I also now getting the Warning for substantial Z offset?
          I've rebooted both my computer and the Duet / Raspberry Pi SBC and reset my router?

            Is there a guide on how to network my Duet/Rpi 4b sbc directly, this wifi issue is a real pain in the backside?

              Can you connect the Pi via ethernet cable to your router/switch?

              Have you done a sudo apt update sudo apt upgrade recently on the Pi?

                Yes. I didn't know if I just plugged the ethernet cable in, and was good to go, or if I need to set anything else up.

                  It should be good to go just plugging it in.

                    I'm just making all the ends for connecting a network. Something I've been meaning to do for a year or so, but in the meantime while still using Wifi, here's my latest bed compensation after M561, Home-all, G32 then G29, and after yet another network error whlie doing so;

                      Same problem connected to ethernet.

                      The bed compensation scanned twice, then about halfway through the 2nd scan (don't know why it's doing this twice in the first place), it through up the network error again.

                      I there away to find if this is my router or Duet3?

                      Just thought about that, so connected the RPi (as I'm using/in SBC mode), directly to my computer via ethernet.

                      Same problem?

                      On closer inspection while running bed compensation again, in places around the bed my Z probe (Tronxy TR Inductive glass sensor), is detecting and shown by the led on top of it, yet looking at the paneldue at the same time it's not detected?

                      Is this a problem with my Duet 3 board, because if it is, I may have issues as I purchased it in January 2021, yet only now installed it?

                        Do you have a new high quality SD card to use in the Pi? I'm wondering if it's an SD card issue when it's busy.

                        You can backup your config files in DWC first. Then download a fresh DuetPi image and burn it on the new SD card.

                          I was kinda thinking that earlier, so download each file from the DWC System Directory.

                          I'm not so sure I actually was connected via the ethernet (I'm on a 2009 mac).

                          An Ip scan shows 2 ip address for the Duet/Pi also.

                          In the mean time I hooked up a keyboard, mouse and monitor to the Pi and same thing again sensor led would signal a sense (if it didn't the bed would crash anyway), but sometimes nothing on DWC Z probe.

                          I'll go and find another sd card an try again tomorrow.

                          Does anyone no how to connect a 2009 mac on a network to the Duet/Pi? I can find the RPi's mac-address and Ip address. Do I use finder. go, connect to server, because it doesn't find anything. I've tried typing in both the mac-address and ip address in connect to server, it goes to connect, but then comes back with "There was a problem trying to connect to xxxx check" etc, etc, etc.

                            Sometimes the trigger is too fast for DWC to capture.

                            On the pi if you turn off the wifi that should force it to use the ethernet. If you use an IP address to connect to DWC you may need to switch to using the IP address of the ethernet port instead of the old wifi address.

                              Would sending M552 S-1 disable wifi, then I can go through and test the current ip address's I have.

                              I was using duet3.local with no cables, then I tried xxx.xxx.x.20, but now I have xxx.xxx.x.39 and xxx.xxx.x.41, so If Idisable the wifi only one of these should work and be ethernet?

                              Ethernet port, ie ls /sys/class/net/, cat /sys/class/net/xxx/address?

                                No, the M552 commands only work in standalone mode when not using the Pi. You'd have to manage the networking settings on the pi itself.

                                  @Phaedrux m552 etc work if using the duetpimanager I think
                                  Edit: they are usable. See here for info https://github.com/Duet3D/DuetSoftwareFramework/tree/v3.3-dev/src/DuetPiManagementPlugin

                                    Thank you your replies and help.

                                    I've disabled wifi with;
                                    sudo apt update
                                    sudo apt full-upgrade
                                    sudo apt install rfkill
                                    sudo rfkill block wifi

                                    Probe sensor led is detecting every time, but Duet/Pi in DWC is still missing probe points?

                                    Is this an SD card swap now, the feed rate of the probe is 120, so it's not going particularly fast?

                                        @Dizzwold Those network errors aren't pretty but they should not affect the code being run on the Pi/Duet. These messages can only show up if the connection between Duet and your device is interrupted, but it's hard to say why exactly they occur. It might be a driver issue, but that is hard to tell. Do the same error messages show up on another device, e.g. on a smartphone or tablet?

                                          I have a 9 x9 bed compensation in place that should run once.

                                          When I run the bed compensation My Z probe (a Tronxy TR Inductive glass sensor), detects every probe point which is shown by the led on top.
                                          In DWC it doesn't detect all the points and runs the bed compensation 2 times and sometimes 3 times.
                                          The probe is detecting, as if it didn't the bed would crash into the nozzle.
                                          It's generally doing 2 runs of the bed compensation, and half way through the 2nd DWC throws up a network error.

                                          So I've now disabled wifi on my Raspberry pi (running the Duet in SBC mode on a RPI 4B), and connected it to my networtk.

                                          I send;
                                          G28
                                          G32
                                          G29
                                          It runs the bed compensation twice. Half way through the 2nd bed compensation it still throws up a network error, while connected to ethernet.

                                          So the problem still persists on both wifi and ethernet.

                                          I'm now going to try it again solely connected with a ethernet cable directly from my Pi to my computer.
