        @CaLviNx I know you can use a USB camera in combination with the pi - but the web server need to support/use it to get video in the duet web interface

            Was it an RJ11 port??? Whoops! Clearly I didn't look at it particularly closely 😆

            My bad!!!

              The Raspberry Pi 4 has an official current supply of 5.1 volt and 3 ampere. According to https://duet3d.dozuki.com/Wiki/Duet_3_Mainboard_6HC_Wiring_Diagram I can empower it by the 26 pin cable also (the note for the 26 pin header in the diagram), but is it sufficient for the Pi 4 or should I better use the official supply?

              And if I shall use a separate supply, I suspect I have to connect the grounds?

                Mine is running quite happily of the 26 way cable mind it is only idling at the moment but has been switched on for about 2-3 days constantly

                    First initial test

                    Duet 3 6HC
                    Raspberry Pi 4 2GB
                    7 inch 1024x600 capacitive touch LCD
                    24V PSU
                    SD card that came with the Duet

                    All seems to work fine 🙂
                    Next, I`ll connect steppers, fans, configure WiFi/Ethernet..

                      I got a question about duet 3 and pi - is the code transfered to the duet before the print Job starts or is it controlled real time by the pi during the print?

                        Should the underside of the drivers and mosfets be completely soldered to the board or is there enough contact to dissipate the heat the way they are?

                          It is controlled real time. This also allows to implement plug-ins to do arbitrary modifications while the print is in progress. For example I have implemented a first version of an Object Skipper, i.e. a plug-in that is given the information on how to identify a certain object in the GCode (many slicers put specific comments in the GCodes) and then will filter out any commands related to this object (or multiple).

                          This allows for a print to continue where you have multiple objects on the platform but printing fails for whatever reason for one of them.

                          I will probably release this early next week.

                              The connectors should be soldered, but not the thermal vias under the stepper drivers and mosfets.

                                So the partially filled vias are OK?

                                  Yes.

                                    Will there be a variant that does not use a raspberry?

                                      The current 6HC board has an SD card slot and an ethernet port that allows you to use it in standalone mode.

                                          No worries. There was some talk about the boards not having the SD card holder or the ethernet jack populated at first so there was a little confusion.

                                            For info, I've been running mine in "stand alone" mode without the RPi.
