      I noticed, before all this crashed, the print cooling fan was spinning but hardly getting going then stopping again

      unplug this as well - the power cycle the power to both the 6HC and the 3HC. Run M98 P"0:sys/config.g" to verify the changes are undone.

        Nothing is happening when I do any commands anymore. It just spins around and around. All things added are disconnected now. The 3HC doesnt blink anymore 😕

          @charles-fraser can you still access the network interface? in that case send M122

                I’ve done that and nothing. When I send those commands the DWC gets stuck in the spinning wheel of death. There is no blinking light on the 3HC

                  @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

                          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.

                                  @T3P3Tony this explains the wiring

                                  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.
