      @martin7404 Oh wow, I didn't take my test far enough as to look for error as the Y direction changes but if it was that far off you can see it visually.

      Are you sure your set screws for that pulley didn't loosen up?
      Have updated to 3.2.2?

        Did you double check your motor assignments against the known bug list?

        https://duet3d.dozuki.com/Wiki/Duet_3_firmware_configuration_limitations#Section_Temporary_limitations

        it looks like you have your Y motors on the duex, z on the mainboard and endstops & probe on the main board.

        i have same setup and all the gremlins went away once i put all the Z motors on the main board and extruders on the duex.

        Most notable caveats are-
        "Endstop switches and Z probes connected to the main board cannot control motors on an expansion board. This is planned to be fixed in release 3.4.

        If you use a Z probe then the Z motors must be connected to the main board. This is planned to be fixed in release 3.4."

          @3DPrintingWorld I have to disassemble to check that with the set screws, but I am sure everything was tightened well. I will have to disassemble . YEs 3.2.2

              Thanks for pointing this out, no one has motioned this so far. I have moved the Z motors to the wifi temporarily but didn't see a difference in leveling so I switched it back. I did not realize this was a issue, I will work on permanently moving X and Y to the Duex and Z to the WIFI.

              Hey @Guillaume-G, you might like to know this.

                You should be able to reach the set screws on the drive pulley to make sure they are tight without disassembling anything.

                    On my three Z stepper printer running 3.2.2 on a Duet 2 WiFi/Duex 5 combo, I have the Z steppers on the Duex 5 and the Z probe with auto bed leveling works fine.

                    You saw the video and you can clearly see the bed leveling movement after the first pass of Z probing.

                      @fcwilt I think we know it can work as it works on yours, mine for six months, and on other builders of the Muldex but according to this documentation its not supported so I would like to eliminate the chance that it could be causing the issue.

                        @martin7404 Are you talkin about the shoulder bolts the idlers are on? I would think it would be less likely those are causing the issue but I guess you never know.

                          That documentation was referring to Duet 3 hardware (6HC, 3HC, 1LC, 1XD) not Duet 2 hardware.

                          RepRapFirmware (as at version 3.3.1) for Duet 3 currently has the following limitations when tool boards or expansion boards are used.

                          Which is why I pointed out that I was running a Duet 2 WiFi/Duex 5 combo.

                            Its seems unclear to me if they are referring to Duet 3 hardware or Duet 3 firmware but they do say "tool boards" which are only Duet 3 so I think you might be right. I hope so, its kind of a lot of work to move things around.

                              Look at it again:

                              RepRapFirmware (as at version 3.3.1) for Duet 3 currently has the following limitations when tool boards or expansion boards are used.

                              The firmware is referred to as RepRapFirmware for Duet 3 - Duet 3 is the name for the hardware line, not the firmware.

                              And the fact that it works on a Duex 5 is pretty convincing to me.

                              Also the way the Duet 2 communicates with the Duex 5 is totally different from the way the Duet 3 boards communicate with one another.

                              And when I discussed the Duex 5 endstop sensor problems on my printer when running 3.2.0 with @dc42 I think he would have mentioned that it wasn't supported. Instead he found and fixed the problem in a matter of days and released 3.2.2.

                              So I'm pretty sure we are good to go.

                                    So checked all the mechanics on the left side. Checked belt tension. Everything is great. Tried different speeds,acc and jerk, played with mottor currents, nothing. During print with X the parked U carriage moves back and forth on every change of direction of Y. I switched back to 3.0 and 3.11 same story. @3DPrintingWorld could you share your PRF 2 config , So I be able to verify that.
                                    I started a print with Right extruder, same story the Left carriage moves during print.
                                    I am starting to think it is a belt stretch(backlash)

                                      @martin7404 I thru a indicator on the U-axis while the X-axis is printing and its crazy accurate while changing direction.

                                        Wow.
                                        As far I see the same problem in X while U is printing.Decided to test withh 2 Y mottors attached to double ZA and ZB connectors on wifi. It seems my board have problem as far ZB mottor is not energised. So it is possible there is something in my Duet wifi board. For now I ordered new board and willtry to move x,y and u to duex and Z mottors to wifi while waiting

                                          What does the soldering on the connector look like?

                                          12v or 24v?

                                            the ZA works
                                            This is the connector for the second Z motor to be connected in series .

                                            To check soldering I have to unscrew the board, I will do it tommorow
