      @IndeX4D ok, now start a print running (you can remove the filament to avoid wasting it) and when you have had that stuttering happening for a while, then send the M122s as above.

      I am looking to see if there are any issues reported on the CAN communications, or driver hiccups or buffer underruns etc.

      if you let it stutter for a while then it will rule out a single hiccup etc.

        The diagnostics above are made by a print when some stutter happened.... or do I need to print for a longer time?

          @IndeX4D it does not look like you were printing a file. I suggest pritning one that stutters a lot and have it stuttering for at least (say) 100 stutters then send the M122 9while its still printing).

          If that doe snot show up anything in the CAN communication, hiccups or buffers then the next thing to try is temporarily switch the axes into open loop mode

            I added a M413 S0 to stop power loss like somebody said. was not working. may that´s the reason it looked like it was not printing.
            I´ll start a print, now.

                    While you are hunting down a FW issue, I'd suggest to use "arcwelder.exe" as postprocessor in your slicer.
                    It's very helpful compressing gcode and reduce SD-card traffic while printing.

                    I don't remember where I found it, but I think it was on github. Maybe others who use it can chime in?

                      @IndeX4D can't see any hiccups, can you try running the same print in open loop mode.

                        New situation:
                        I used cura 5.0 insteaf of 5.3 --> almost no stutter
                        Then I increased the stl output stl (0.001mm) resolution.
                        Then I sliced and the g code had around 10mb instead of 2.7mb. So more steps are not a hugh problem - I think the new cura version make to many strange corners. I´ll test it more and more the next hours and will tell you the exact Issue.

                        I was a bit lazy and I haven´t told you, that I usally print with up to 250mm/s and I had no stutter- now I was printing with maximum 100mm/s, so I could not imagine that the board is to slow. Only different was a very natural curvy shape and a much bigger hotend/ layer width/ with much more filament output.

                        Now, I after was printing 2.5 hours without stutter, I had 1 little layer shift but some underruns. I don´t know where this comes from. I very often ask, If 10 meter cable is to long or need higher bitrate?`

                        Layer shifts has never be a problem, so I just keep an Eye on it.

                          @IndeX4D lots of very very short segments can cause stuttering but AFAIK modern slicers have a setting to set the shortest allowed segment length to something reasonable.

                          for example on cura:
                          51f95f1b-099c-4f12-8f3b-9c00332e262d-image.png

                            yes I know, but Cura 5.0 is working, Cura 5.3 with same settings is horrible.

                            Cura 5.3 is producing small corners, which is not fine. Also it replaces z seams to this small unvisible corners.

                            Setting up the resulution in cura 5.0 to 0.001mm is still working. Gcode has 50mb instead of 5 and it´s printing with 200mm/s completely ok, so I don´t understand why I should reduce any resolution when the Duet3 mainboard can work with heavy loaded gcodes.

                            Edit: Layer shift came from bad quality rj11 cable -- replaced with rj11 cat5e cable. Printer is running much smoother and no layer shifts at all, also when shaking thr cables a lot!

                              ok so to confirm, you have tied this down to gcode generated by Cura 5.3 causing issues which are not present in cura 5.0? and that is the same no matter the version of RRF?

                                In the Cura settings... is RepRap set for the "GCode Flavor" ?
                                It can be found in the printer settings, where the start and end GCode is also entered.
                                (Settings -> Printer -> Manage Printers... -> Machine Settings).

                                I added a M413 S0 to stop power loss like somebody said. was not working. may that´s the reason it looked like it was not printing.
                                I´ll start a print, now.

                                M413 does not know the duet.
                                You probably mean M911: Configure auto save on loss of power (Duet GCode Dictionary Link) !?

                                DDA5X... 0.9° Stepper... Linearrails... Duet 2 Wifi... PT100 Board... Duet IR-Probe... Dyze Pro Kit up to 500°C.. etc

                                  yes, I think cura is the main source. Playing around with resolution etc in cura with 5.0 is always fine. Also when printing with with very high resolution.
                                  I´m not sure, if I do anything wrong with cura 5.3.
                                  Cura 5.0 is running fine for this project.

                                  thank you, gcode style is enabled. I just took a wrong command from youtube ;/ latenight.

                                  I mean in general the printers are working very good since 3.5 - especially closed loop steppers. They make me happy! 🙂
