      Hi, some updates
      I received an endstop cable
      And yesterday, after a month or two 😄 found some motivation to start checking how it works
      So here is the list of what is checked right now
      Power applied via standard for FFCP cables is working OK
      I can connect to WiFi via Big Dipper when 24v is applied OK
      (though you can't use USB 5v and 24v interchangeably to configure WiFi, because you have to move the selector physically. So if you want only to connect to USB and configure WiFi you have to move selector. If you want to use 24v and have a working WiFI you have to return the selector to the default state)
      XYZ motors are moving when command is sent via WiFi OK
      XYZ endstops are flashing when triggered OK
      (though I don't know how to check whether endstops are working as expected before I try to home axis)

      Next steps
      check fans
      check thermistors
      check heaters
      Then close the case and try to configure the print

        Next update:
        Extruder Fans OK
        Cooling Fan (with ability to control air flow from 0 to 100) OK

        Next steps:
        Forgot to crimp board fan cable TODO
        Fix wrong wiring of the Bed thermistor TODO
        Have to recrimp x axis motor cable TODO
        check thermocouples are working when there are no config errors TODO
        and heaters
        (found a thread about bed thermistor here - https://forum.duet3d.com/topic/7285/flashforge-creator-pro-heat-bed-wiring/2)

          Next update:

          • By using the thread above now I see the bed temperature via a thermistor OK
            used first two cables out of 4 (white and green in my case)

          • Config from this thread helped me to turn on thermocouples (though i had to downgrade them to thermocouple-max31855 from thermocouple-max31856) OK

          • board fan working OK

          • extruder heaters are working OK

          • bed heater is not working, I'll check what's wrong next time TODO

          • Also I need to close the printer TODO

          • LEDs are not working and I don't think I am going to fix that in the nearest future NOT_HAPPENING
            I might replace the screen with the one from FYSETC TODO

          • Fix config issues that i can come across TODO

          • And finally print something TODO

            Hi, everyone, if you are reading this, then I....

            Finally finished assembling the printer after the upgrade)

            • I managed to home all axes OK

            • Added a fysetc 12864 screen, though it needs an adapter OK
              I used the menu made by jadonmmiller
              But I'll have to update the UI because this one is only for 1 extruder setup

            • Drivers are doing their job, I hear almost only fans) OK

            • Figured out why the bed was not heating, it has a separate power input, and I had to buy another cable and crimp it OK

            • For now I skipped BLTouch sensor installation, because I don't want to make it even harder.

            • I started to configure the printer
              And it seems that I'll have to read Gcode docs and learn Gcode, because it is everywhere
              From screen menu and configs to printing instructions

            • At the moment I have to find Gcodes to load/unload filaments and check that extruders directions are correct TODO

            • Then I'll have to configure Cura TODO

            Somehow I used the printer without Gcode knowledge before that)

              So I found gcodes in docs to load/unload filament
              Then I had to change some configs for extruder drives
              And now I got a problem with thermocouple board because there is interference from stepper motor cabels

              It seems that Flashforge fixed that issue in their version of mighty board, because i did nothing to the cables other than changing connectors

              I have a 0.2v daughterboard and I think in 0.2v there was no capacitor
              according to this thread adding a capacitor helps https://forum.duet3d.com/topic/1270/thermocouple-issues/10

              @dc42 Hi, sorry to tag you, but can you please confirm that in the daughterboard 0.2v there was no capacitor?
              As far as I see from the picture of the daughterboard on the official site, the new version has some extra components on top of it
              mine


              from the site

              And is the process the same for the 0.2v board?

              • Take 4 capacitors
              • find a ground plate
              • solder capacitors to each pin and to the ground

                Ok, I found your answer for the same question here
                So i think one of the ways to fix that is to get the wire out of the casing

                  But moving the thermocouple wires away from the other wires didn't help
                  Only one of the thermocouples for the right extruder now is working correctly, but i can't say exactly what helped, maybe i crimped it better. Although it still can catch the interference from the other thermocouple, even if using it alone does not provoke interference
                  They are still near the drives on the head, and i think that is where they pick this interference

                  I wonder if using a thermistor will help
                  Flexion extruder allows to install it, and the board has ports for temp sensors

                    recrimping didn't help, i think I'll have to go with the thermistor
                    that way i will not need a daughterboard and i guess that might help

                      Captain's log
                      Installed and configured thermistor NTC 3950
                      Now I don't see 2000 degrees when extruding or retracting filament

                      But my printer shuts down in a minute after that and then it is trying to restart over and over again, until I turn it off and turn on again

                        It seems that @dc42 helped me again, even without saying a thing)
                        I found my answer here https://forum.duet3d.com/topic/15897/duet-wifi-resetting-part-way-through-prints/30
                        I disabled endstops, and it seems that the problem is solved
                        Though I need to wire the endstops properly

                            Sooo, I did recrimp endstops
                            Thought now it is ready to go,
                            connected Cura via plugin OK
                            Started to heat the bed
                            After the extruder fan started to work the printer started to restart again
                            Then in a few minutes, after the printer cooled down, I thought I'll try to change some settings for fans
                            But the printer began to restart in an idle mode. I did nothing, and it started its disco.

                            Now I don't know what can be the problem
                            Maybe something should be done to a board fan frequency, that is the only thing working when the printer is idle

                              Ok I started from scratch
                              I think the problem was with the board loosely fixed, it might have touched some parts of the case
                              I also checked all the wires and reinserted them, trying to fix them as tight as possible
                              Now it seem to work

                              Started the test print, I'll write an update after that
                              For now I hear the sound of silence and it is great
                              I'll have to change the coordinates though, the print started on the corner of the build plate

                                  Finally it is working
                                  Though I need to adjust tool offsets a bit more
                                  And I also had to change the cooling fan number in cura settings for every extruder to the pin number of the fan (in my case fan #3)
                                  And I need to try dual extruder printing

                                  Thank you all who helped me achieve this.
                                  Hope my story will help somebody)

                                  I'll publish my design for the Big Dipper holder and my configs a bit later.

                                      New update:
                                      After some prints, I saw issues with layers positioning at different heights. Tried to tighten the belts aaand my printer stopped working)

                                      For some reason the problem occured only when the bed was heating, so I recrimped the thermistor, because I made a mistake and the cables were in reverse order. Then I recrimped the bed power cables that are connected to the PSU. And I did that for a week or even more every evening)
                                      I found out that I used 1.27 mm2 cable for bed power and that I had to use the right crimper tool
                                      And I tried and tried, again and again to crimp even better
                                      Until I checked the bottom of the board holder and found out that extruder cables touched the screw
                                      I guess that was enough to short the board
                                      My board firmware even got corrupted and I had to reflash it via USB
                                      It even stopped connecting via serial port, only direct USB download of the .uf file helped me

                                      Then i also had to fix other cables as well that touch the closing door of the bottom side of the printer

                                      So I write this to warn you to be careful with your wiring)

                                      But I still have this issue with my layers though. So I will continue to look for a solution.

                                      Also I took the opportunity and installed the Z-probe, though I need a holder to start using it
                                      And I haven't configured it yet

                                      Also I found some useful resources along the road
                                      For example a video about crimping -

                                      And a guide with pictures how to wire a dual extruder printer to the Big Dipper
                                      https://www.youtube.com/watch?v=GZOh1NzqzzU
                                      Although the cooling and board fans seem to be wired incorrectly there

                                        I guess another problem is with my power supply like @garyd9 had when turning on the bed heater
                                        https://forum.duet3d.com/topic/3553/converting-a-flashforge-creator-pro-to-use-duet/3

                                        I wonder what should I take into account if I want to use a 500w 24v PSU
                                        Should I replace the original 1.5 mm2 power cables?
                                        Will the board survive the current?

                                        PS: it is interesting that I had some almost successful prints even with a 320w PSU
                                        Although there were signs of missed steps

                                          Ok, I think the PSU was not a problem, because I get shutdowns even with the 500w PSU after trying to run a bed heater. Though I had some restarts in the idle mode too. Also after the shutdown it was hard to recover on the old PSU. With a new PSU it's the board manages to restart. Or maybe I crimped the wires a bit better now, but not enough for the bed heating

                                          Two times I managed to catch an error Vdd Brownout

                                            @Inlinebrother although your board is a big dipper as it uses the same MCU, dc42 may be interested in the output of the hard fault issue.
                                            Please see the thread here https://forum.duet3d.com/topic/36689/random-hard-fault-resets-on-duet-3-mini-wifi/

                                            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
