    @3mm Thanks for the information. You didn't update to 2.05.1? The M122 command reports "Used output buffers: 6 of 24 (8 max)", which is high. There were quite a lot of fixes in later RRF 2.x versions for this issue.

    To update, you should be able to upload this file to DWC: https://github.com/Duet3D/RepRapFirmware/releases/download/2.05.1/Duet2Firmware-2.05.1.zip
    Download it as a zip (don't unzip it), and upload it to the Duet via DWC > Settings > General > Upload Files button.

    Note that this WILL update DWC to version 2.x, which is a bit different from 1.x. You can go back to 1.x if you prefer it.

    @droftarts (& DC42),

    Ok, I uploaded v2.05 to the printer, and while, the new user interface is taking a bit of time with which myself to become accustomed, the http time-out (EtherNet dropout) problem has vanished, or so it seems. I have not tested every function but the newer version seems to have remedied the problem.

    Thanks for the link and the instruction for installation.

      Well I finally have it working. I discarded the xubuntu 20.04, just too buggy and virtually no information that matched the mods from the ubuntu fork. Now, I need to do is make hack together an EtherNet 'switch', a couple of toggle switches that routes the laptop either to my InterNet router or to the printer, OR the printer to the InterNet router! I've got all the configurations working. Essentially very similar to your strategy.

      Thanks for the indepth answer.

        a bit different from 1.x. You can go back to 1.x if you prefer it.

        I clicked the 'Revert' to older user interface button, but where is the revert back button? I'd be interested to try to use that new interface for a time, to see how it works. Need I reinstall the whole FW packaged to regain that user interface?

        Thanks in advance...3mm

          @3mm the 2.05.1 release has an early version of DWC 2, and includes a button to revert to DWC 1 for the current session. Note that DWC 1 is no longer being developed. Later versions of DWC (and you can use up to DWC 3.2.2) do not have the revert button. If you want to use DWC 1, which is still on the SD card, you can:

          1. (Temporary) Appending '/reprap.htm' after the printer IP address/name in your browser address bar (updating to 2.x won't have deleted the old DWC v1.x files, but it's worth updating them too if you haven't already).
          2. (Permanent) Deleting the ‘index.html’ and/or 'index.html.gz' file in the www folder on the SD card.

          Make sure you are using the latest DWC 1.22.6 version; it’s in the 2.05.1 repository.
          Manual for DWC 2 and 3 is here https://duet3d.dozuki.com/Wiki/Duet_Web_Control_v2_and_v3_(DWC)_Manual

            Ok, will do. The screen re-reverted user interface returned after a power-cycle. I getting used to it, at first things seem scattered randomly about, but there is actually a logic strategy in it's implementation. On a 38,1cm/15" LapTop screen the fonts are a bit small, but with the 'dark' its useable. I'll get used to it. I printed a few things tonight using the Linux box and the new version. The user interface is obviously designed for production!! Heh heh. Gotta love it!

            Thanks for everything...3mm

              I find the opposite! I usually have my browser zoomed out to 90%. This is on a 15" Retina MacBook Pro. I guess you can always zoom in, though. You can also hid the side bar by clicking the 'three bars' icon at the top of the page, next to the machine name, to give yourself more space.

                I find myself having a related problem:
                I want to use my Duet 3 in standalone mode but hook it to the network using a direct connection. Not to a Windows or Ubuntu PC but instead to a raspberry pi running raspbian (no, I don't want to run the Duet 3 in SBC mode for reasons...).

                I already configured the raspi to work as wired router after this tutorial. It even has a DHCP server and I can connect my PC to the pi directly and can access the internet through this without any problems.

                But when I connect the Duet 3 to it I can not access the DWC by
                either entering the ip address the Duet gets assigned from the DHCP server on the raspi (which I can read from YAT)
                or entering the statically assigned IP from the raspberry pi ethernet adapter
                (there is conflicting information on which one you should use here in the forum and here in the documentation)
                subnet masks are all matching 255.255.255.0

                I have the feeling that there are the right people here in this thread that can help me... I don't know what else I should try rn.

                BTW if I connect the Duet 3 directly to the ISP router I can access DWC no problem entering the IP address I get from M552 in YAT.

                ------ probably unneccessary information ------
                At first I set up the raspi using the same subnet as in the above mentioned tutorial 192.168.100.xx (192.168.100.1 for the raspi eth0 and 192.168.100.50-240 as DHCP range with the Duet 3 then being assigned 192.168.100.50) but noticed that 192.168.100.1 actually connected me to the setup page of my ISP router. I then switched to the 192.168.101.xx subnet and connecting my PC to the internet through this still works but I still can't connect to any IP address (neither the .1 of the raspi nor the .50 of the Duet 3 which again I checked in YAT)

                I also already disabled the DHCP server on the raspi and assigned a static IP address to the Duet 3 but that made no difference
                ------ end of probably unneccessary information ------

                  @schild0r , have you tried using a crossover cable? The Duet Ethernet port doesn't auto-switch, and I don't know whether the RPi Ethernet port does.

                      I noticed that even if the PC can connect to the internet through the direct connection with the raspi, I cannot ping it with another device from my wifi network. I think if I can manage to get this working I will have my solution.

                        I happened across this and have wrestled with such problems mightily in the past (usually on a customer site just prior to a presentation).

                        If I missed this suggestion in the thread - I apologies but ....

                        When trying to connect PC-PC(or Duet) 1:1 via an ethernet cable -- its best to make sure than neither has it's wireless connection active. That way - you are trouble shooting only one problem (not a potential combination of interactions).

                        Also - turning off both firewalls until you get it working

                        Hope this helps.

                          well the problem is that I am not troubleshooting the wired part of the PC-PC (RPI-Duet) connection but the wireless part of the PC: (:Router:) :RPI-Duet connection (wireless being the colons)

                          Also - turning off both firewalls until you get it working

                          Hope this helps.

                          that did not help either unfortunately

                            Ah - OK. So the dash - between RPI and Duet is wired and the rest is wireless. In other words you want to bridge the ethernet to wlan on the Pi.
                            I've done that in the past but cannot remember all the ins-and-outs but it was somewhat convoluted (dnsmasq, iptables and etc.). From memory - the next time I had to do it - I found a longer ethernet cable and went straight to the router 🙂

                            This looks like it may be of help:

                              @stuartofmt after asking another friend I ended up with a different tutorial that did the same thing I already did only a completely different way (I honestly have no clue what the script does I just copied to the pie, but it keeps the connected devices in the same subnet) and it works. I think your link may have also helped but this was a 3 minute solution.

                                FYI: I am using a RPi 4 B and it looks like it does auto switch. It's now working and I can use either cable

                                  I'm always amazed by the number of alternative packages to do "the same thing" along with instructions that sometimes work and sometimes don't. That tutorial takes a slightly different approach but better still WORKED FIRST TIME !!

                                  Congrats and thanks for posting the link.
