      @charles-fraser it sounds like that 3d touch has caused an issues (or resurfaced an issue from the previous heater problems) with the 3HC. I remember you had issues with it right at the beginning - is this a new 3d touch or your original one?

      We previously reset and reflashed the firmware on the 3HC. I think that's the step to take again now:

      To force a firmware reload on the 3HC set all the dip switched to 0, power cycle the 3HC, you should see the diag light flash a bit. when its showing steady flashing in sync with the mainboard, switch the dip switch back to 1 as it was then power cycle the 3HC.

        I have done that and still no flashing light

        Also this is the same 3D touch as before. Now I remove it but still the 3HC doesnt flash. Before when I removed it the 3HC started working again. There is nothing on the board and it’s not working

            Any help? Is it fried? I can't believe it fries just because of a short that doesn't make sense to me

              Is the 3.3v LED lit on the 3HC? (its with the other power LEDS in the top left og the board as you have it oriented.

                Not sure what is going on here? why were there two sets of wires going into IO2?

                  None of this is plugged in any more. I explained this in my post with the description of the wiring of the 3D touch above. Please have a look.

                    Nothing is plugged into the 3HC

                    These are the lights that are on:

                      I’m sorry it’s a bit of a fudge but I have only been able to get the 3D touch wired up (I hope correctly) with the 3HC, IO_2

                      Here is what the wiring from the touch is supposed to be:

                      418497BB-44CB-459F-B606-5276C3D52852.jpeg

                      But the 3D touch I have does not have a white wire, it has a blue wire though so I am guessing that’s the only difference.

                      I have to connect the BL touch to two different cables, each with four wires in them to reach the board at the other end of the printer. In one of the cables, two of the wires are already used by the NTC thermistor so it looks like this:

                      C0A1A2D2-648A-486F-B729-2C97DDC6811F.jpeg

                      Then I can only reach IO_2 on the 3H with all that following this diagram:

                      76A4FAD0-34A6-48D1-9BB1-19A68325A9AB.jpeg

                      Which looks like this:

                      4B557514-9CF8-43D8-BAA6-CEE607C66206.jpeg

                      40DCE328-A7C2-4A3C-9C62-8BDB2E453241.jpeg

                      I hope that’s correct! I’ll try to change the code and hope it works!

                        Hi please advise. Do I need to buy a new board or what to keep things moving forwards?

                          @charles-fraser It looks like the 3.3V regulator & possibly other ICs on the 3HC was blown by the 3d touch. I suspect given that it caused issues before that it is faulty, I don't know much about the 3d touches but if they are the same as the BL touch internally they should not blow the board by just mis wiring.

                          Yes you need to replace the 3HC

                            Okay I will as soon as I have some money. Is there a way to diagnose what caused this? Is a fan wired the wrong way or a 3D touch really able to blow a whole board?

                              @t3p3tony hi Tony, I have the replacement 3HC now and am awaiting a BL Touch to arrive next week.

                              I’ll try to reconnect the new 3HC and rewire it as it was before just leaving out the fan and 3D Touch.

                                  @t3p3tony Hi Tony,

                                  Sorry for the radio silence. The Marquee that I am storing the 3D printer in became quite damp and would drip with moisture when it had rained and any sun shone on a cold day, dispite the cotton inner lining and ventillation I had made for the dome. So I wrapped up the printer in some synthetic sheets and tarps to mothball it over winter. I am now planning to get back into it, starting in the next couple of weeks. I will work to connect everything only through the second (hopefully not faulty extruder block).

                                  Thanks
                                  Charles

                                    @t3p3tony marquee was destoryed in the storm. Project is mothballed till I complete/afford an upgrade to the frame to include cbearm linear actuators from openbuilds to mount my MDPH2 extruder on as per Dr. D Flo’s work

                                    Thanks for your help getting this far

                                        Hi dear Duet team and community. I’m happy to say my Green Camp business is making income so I can afford to keep making some progress:

                                        Update:

                                        1.cutting down the Dowell frame so it fits in my garage:

                                        2C3A07DC-785A-4A3D-A1DB-818FCDF09572.jpeg

                                        2: upgrading the X-Y gantry with openbuilds’ 1500 C-Beam Linear Actuators:

                                        1EDAF468-8840-4425-B171-E7A6EEE5EE19.jpeg

                                        62060311-9E03-4AD6-B419-2A789FA8B5FD.jpeg

                                        BF959AB3-5888-4C70-941B-EDF662A11CFB.jpeg

                                        63AF6047-C49B-4D4A-A977-83A4BD966182.jpeg

                                        This will allow me to run the Massive Dimension MDPH2 Extruder (I crowdfunded for one last year and have it on my desk waiting) just like Dr. D Flo is teaching us how:

                                        link text

                                        Present situation:

                                        • The 6HC, PU and Raspberry survived being drenched for 3 days in the hurricane!!! (Kudos to Duet!!!)

                                        • Old 3HC shorted by fan with and needed replacing

                                        • New 3HC has arrived needs to be fitted and firmware updated.

                                        • What’s the console command that updates the 6HC and 3HC again please?

                                        • In order that I don’t fry another 3HC, I need to learn how to determine the polarity of the wires of the fan and the pins on the board to match them

                                        • I need to work out what is the expansion board I need to drive the MDPH2

                                        • I need to workout the firmware config file. I will ask Dr. D Flo for his

                                        • I need to work out how to reattach the 4 X lead screws for the Z axis / heater bed after I cut them down to match the decrease in size of the printer that I had to make so it would fit in my garage.

                                        204C3F94-C362-4498-A7ED-22AD445744E2.jpeg

                                          So latest update is that I have installed all of the C-beam actuators, installed new ball thread rods and cut those and the slide rods to fit onto this frame since it has been cut down to fit inside the garage.

                                          The next steps would be to:

                                          • Define what parts are still needed for the printer & order

                                          • Plug kinematics (X Y), test

                                          • Plug Z Axis, test

                                          • plug endstops, test

                                          • plug probe, test

                                          • plug heaters, test

                                          • plug bed, test

                                          • leave the AC to the end

                                          • connecting the extruder requires a metal plate to fit onto the C-beam trolly

                                          • Connecting heated bed
