      I keep losing connection with the board. I just get the standard AJAX message and no explanation. Its pretty random, Just now I connected, everything looked good, then about 30 sec in it said it disconnected. Before it was doing it in the middle of a print. The print kept going and finished, but I could only stay connected for a couple of min at a time. When that one finished i rebooted the board and my PC to see if that helped. Its hit or miss now. How do I track this down ? So I can give more useful information.

              I have the same problem as far as I can tell. I have the ethernet with the newest beta. Let me know how I can contribute.

                  Usually there is a little more detail provided in Ajax error messages. Which Duet Web Control version are you running?

                    I am getting " Communication Error

                    An AJAX error has been reported, so the current session has been terminated.

                    Please check if your printer is still on and try to connect again."

                        The firmware version you're reporting isn't the Duet Web Control version. You can check the DWC version from the settings tab in DWC.

                          Perhaps there is an IP address conflict between the Duet and something else on your network?

                            Nothing else is close to the number that the router assigned it.

                              I had a similar problem when the signal strength at the printer was low. I setup my nearest AP with a unique SSID and changed the printer setting to use that SSID to be sure the printer was connecting to the that specific AP. Then the signal strength was much better and the problems went away.

                              Printers: a small Utilmaker style, a small CoreXY and a E3D MS/TC setup. Various hotends. Using Duet 3 hardware running 3.4.6

                                I just connected and it forgot that I set it to the dark version of the screen layout. grr
                                is the version I just listed not stable, if not which one should I look for?

                                Error reason: timeout

                                  M552? I have that set to what my router gave it as an ID

                                    No wifi here. I will be changing out the switch next week. I’ll pay attention and see if the disconnects go away. Everything is dhcp and I haven’t had duplicate up issues before.

                                      the router has the Duet listed as a Static address vs DHCP, just looked, its is also the only device that has 3 digits for the last sequence of numbers.

                                        Can you confirm that you only have one Duet on the network? I had problems connecting to a Duet Ethernet yesterday, until I realised that I had a Duet 0.6 on the same network and they were both using the default MAC address.

                                          I only have one board, and only one is listed on the router info screen. it has My computer, my laptop when its on, my phone and the Duet board. short list so its easy to spot.

                                          Another oddity showed up this morning, the small print I was doing, a replacement part was nearly finished. I could see the part was on the last few layers. yet the DWC told me I was only 56.6% done. It has been spot on before. Down right scary in how close it has been till this. I will be keeping an eye on it.

                                            That usually means that you have a G1 Z command in your end gcode to raise the print head when the print is complete, and that command is confusing the object height detection. The remedy is to add a comment starting with ;E to that line.
