      Now I am getting the same SPI connection has been reset error when bed leveling G32

            @KCMARINE You may want to try the stable release version (3.4.5) to see if you have the same problems. If things work with 3.4.5 then it would probably be a good idea to report the above in the beta section of the forum.

                Thanks - what's the process to roll back the firmware - I tried to do this by uploading 3.4.5 to DWC, and it did not work - so I am guessing I have to reset and erase and reinstall with BOSSA

                  @KCMARINE Are you using an SBC setup? Can you still talk to the board using DWC after you tried to install 3.4.5?

                  It looks like you are still on DSF 3.4.5

                  @KCMARINE said in Warning: Lost connection to Duet - help needed:

                  Duet Control Server v3.4.5

                  So you had a mixture of 3.4.5 on the SBC and 3.5beta1 on your Duet board. That's probably not a good idea. Did you deliberately install the beta? What steps did you use to do that?

                  This is probably not good:

                  TfrRdy pin glitches: 298

                  But it may be a side effect of mixing different versions.

                    @gloomyandy, thanks for catching that, mate.

                    A question, please, Can you advise if the MB6HC running 3.4.5 and EXP3HC running 3.4.4 will work?

                    What I did is keep the SBC on 3.4.5 - no change.

                    I removed the Duet 3 MB6HC board from the machine - erased the firmware, and reinstalled it with BOSSA version 3.4.5.

                    I also erased the Duet EXP3HC board and used DWC to load version 3.4.4 as I do not see a later version in the git repo - 3.4.4 was the last release.

                    Confirming:

                          @gloomyandy - recap to answer your questions

                          Are you using an SBC setup?

                          Yes, I downloaded https://pkg.duet3d.com/DuetPi.zip and flashed the SD card.

                          Did you deliberately install the beta?

                          Yes, did make the upgrade

                          What steps did you use to do that?

                          I made the upgrade by downloading the 3.5 beta from the git repo and uploaded to DWC then installed it unknowingly that it may conflict with the SBC 3.4.5

                          Can you still talk to the board using DWC after you tried to install 3.4.5?
                          .Yes, however SPI connection reset and timeouts are still happening

                          It looks like you are still on DSF 3.4.5

                          Yes, now I have downgraded all firmware to match the Pi SBC and problems still remain

                            @KCMARINE So you are now on 3.4.5 on for both DSF and RRF (at least that is what your last posted M122 shows). Can you post another one just so we can be sure. What SBC are you using? Is it a raspberry Pi (which model) or something else?

                              @gloomyandy thanks. I can confirm the following:

                              SBC is Raspberry Pi 4 Model B

                              and M122

                                @KCMARINE are you using the supplied cable between the pi and the duet? Can you post a photo of it's routing so we can see what's near it etc?

                                    @KCMARINE Yep both versions match. Could you also post a picture showing how the two boards are connected. After that I think this is one for @chrishamm

                                          Thanks for the help - I appreciate all that you do

                                          I am out of ideas.

                                          My last attempt/thought is to flash another SD card with a new copy of DuetPi.zip and see what happens!

                                            Success - after flashing a new SD card with DuetPi.zip I am happy to report that I have no more communication errors and I can print my first calibration cube.

                                            I believe that the issue may have been caused by the additional motion installation for the Logitech webcam

                                            https://www.instructables.com/How-to-Make-Raspberry-Pi-Webcam-Server-and-Stream-/

                                            The strange thing is I have this running on another SBC Pi 4 and MB6HC running 3.4.5 on a delta with no issues, guessing it could be a compatibility issue with 3.5 upgrades and then a downgrade, just a stab in the dark.

                                            Thanks again for your support gents - very much appreciated.
