      I verified the build time. Following the firmware update the reset worked my first go at it, the second go at it took about 10 seconds before the LED powered on.

      The attached video is capturing the third and fourth attempt at resetting the board. I had to reduce quality and cut the video short but the fourth attempt was about 50 second connection, and I tried once more after that and it was immediate.

      If firmware updates have an effect on the behavior of the LED/connection, could that be suggesting that the board has the potential to work? I have have seen an improvement, we started at the range of 10-30 minutes to connect and now we're down to the range of immediately to 50 seconds tops.

        Thanks, @kroybal. I think this board has potential to work, but you've suffered long enough. So I'd like to get a replacement sent to you, and the original one returned to me for further investigation. Who did you buy it from?

          @dc42 I will get in touch with my boss and owner of the machine. I believe he got it from filastruder.

            @kroybal, was this resolved by exchanging the EXP3HC board?

              @dc42 I do not believe I was ever put into contact with filastruder, I suppose I was awaiting a response.

              At any rate, I am back simply due to the same reasons stated above. We have made do with the bug (I am actively waiting for the sync LED as we speak) but I was curious of the latest Firmware updates, I believe I checked your account and checked the latest post that I could find in regards to firmware updates was your post from January 5th, 2021.

              I am currently working with RepRapFirmware for Duet 3 MB6HC 3.2.2 (2021-02-11), I will have to uncover the EXP3HC firmware once its sync'd, however likely not necessary, it is still the same (if stated above.)

              Anyways, I could attempt another firmware upgrade before going through the process of an exchange.

                3.3 final was released not long ago, and 3.4 beta2 was released just the other day.

                If that has no improvement, please send an email to warranty@duet3d.com and CC your reseller. Include a link to this forum thread and the details of your original purchase. You'll receive a reply with a form to fill out. We will make a note to have the board redirected back to DC42.

                  Update:

                  I got in touch with Filastruder, turns out my warranty on the board was out of date. Not a problem, I purchased another MB6HC and its still encountering the same 30seconds to 45 minute sync time with the EXP3HC board.

                  Both are up to date firmware wise. Could it be the oscillator on the EXP3HC? I had a few other boards installed (now have been removed) so my serial port is 15 I suspect its not a problem regarding performance, but if it is I could dial that down now I have no other boards beyond the two stated.

                    @kroybal what bootloader is on the 3HC? It's reported as part of M122

                    Owns various duet boards and is the main wiki maintainer for the Teamgloomy LPC/STM32 port of RRF. Assume I'm running whatever the latest beta/stable build is

                      @kroybal this will most likely be resolved by updating the bootloader on the 3HC.

                        Thanks for the guidance! It was out of date.

                        @dc42 said in CAN connectivity: Duet 3 MB6HC to EXP3HC:

                        @kroybal this will most likely be resolved by updating the bootloader on the 3HC.

                        This resolved my issue, when I updated the firmware and forgot to do the bootloader as well.

                        Appreciate the help!
