        Thanks. Will take a look at that. In the meantime, to try and get you back up and running, do you have another SD card you can use to load a fresh copy of DuetPi image? You can copy over your config files, etc to the new setup.

              @phaedrux being a non expert here, the problem clearly appeared when the upgrade process upgraded these packages:

              Is there any way to manually downgrade the version of them to the known version that works with the DWC and DCS?

                @tinchus It looks like DSF is having problems with inches and I'm going to investigate why. Since DSF defaults to mm, you should be able to rename config.g temporarily, up/downgrade, and get DSF to function again. Is it possible that you switch to inches somewhere in your config files via G20?

                You can move config.g to config.g.temp via mv /opt/dsf/sd/sys/config.g /opt/dsf/sd/sys/config.g.temp from a Linux console (e.g. SSH). After that you should be able to connect via DWC again.

                    @chrishamm It didnt worked. I renamed the config.g as you instrected me. DWC still doent worked, I rebooted also with no sucess either.
                    I checked config.g, no change to the fie was done, I even manually inserted a G21 command to be sure it is in mms, and it didnt helped.
                    How can I downgrade from the ssh console to the previous version of the softwares that created this mess?
                    Right now there is nothing to upgrade, I tried the sudo upgrade method but it says everything is up to date.

                      @Tinchus Then please try to restart your board and make sure config.g is not executed on start-up. From your log I can clearly see DSF tries to deserialize in [which DSF thinks should be inch] and there is no other reference to "in" in RRF so I strongly suspect there is G20 somewhere in your files (maybe by accident, I don't know):

                      DuetControlServer[1920]: System.ArgumentException: Requested value 'in' was not found.

                      If it still fails to start after power-cycling/resetting the Duet, try to erase the firmware and flash RRF 3.4.1 manually as per these instructions and a USB cable: https://docs.duet3d.com/en/User_manual/RepRapFirmware/Updating_firmware#fallback-procedure-2

                      The bug that makes DCS crash in this particular case will be fixed in the next version.

                        @chrishamm Hello. Just in case: my setup is a SBC duet 3 with a raspi connected. So the software problem is on the raspberry. Can I just put a sd card with a backup I had. Version on that sdcard is 3.4.1, and firmware on the duet is already 3.4.1
                        Would that fix it?

                        Or: is there a y way I can reload everything through the ssh connection?

                          @tinchus Can you connect a USB cable to the Duet and collect the output of M409 K"inputs" F"d99vn" from a serial console?

                            @chrishamm Im not that skilled jajajajjaa. This duet3 is conected on SBC mode to a raspberry. If I connect directly to the USB port on the duet board, how do I access the interface? Everything on my setup is done for SBC mode. Do I need to disconnect all cables from the duet?
                            Right now I dont have personall access, but can find a way (is a printer I assembled at the school, that is why if I can do things remotly would help me a lot)

                              @tinchus I understand it is connected via SBC but I am still not convinced that you don't have G20 anywhere in your config/job files. Showing the output of that command should confirm the origin of this instruction. See https://docs.duet3d.com/en/User_manual/Troubleshooting/Terminal_Emulators

                                @chrishamm I have checked config.g and I can say there is no G20 command there or any "inch" command o mention. I have not checked the jobs folder. I can just erase all gcodes on the printer from that folder and see what happens?

                                    @tinchus You can now try to upgrade your system using apt update/apt dist-upgrade. The version that we released today should fix your issue, and the upgrade command does not query the affected object model key.

                                      @chrishamm Hello. The update fixed the issue. Sadly, I had scheduled the execution of your requested command for monday, so I cant provide you with the output of that command in order for you to fully diagnose the problem.
                                      But this update did the magic. THANKS!
