      Looking at your gcode file I notice you've got the M572 at layer change intervals to test. There is a slight pause when M572 is changed. I'm thinking that this is actually what you're seeing. You can see the pause yourself if you manually change the PA value from the console during a regular print move. It seems rather pronounced in your video though, perhaps a combination of the M572 change pause and the slow layer change.

      Is it pausing on every layer like that or only when the PA value is changed?

        something is changing with pa see the picture https://photos.app.goo.gl/HmsNtTfBj33gNjxAA

        ->Is it pausing on every layer like that or only when the PA value is changed?
        the pause is every layer.. the printheat stops then is a pause after that the z-axis will go down and the print starts again.

        I print now the version with firmware retract but its still the same ... in this print i have changed the m566 in stepps up to 800 and the m201 up to z1500 the only thing what changed was the noise of the z-axis

          Is that correct? You're reducing the extruder to 32.5%?

            yes because the bmg extruder have so much power that he have kill the bowden connector or if the nozzle was to near on the printbed the extruder have pressed the filament in to the extruder case. So i have reduced the power so var that the stepper will lost stepps if the filament hangs or the hotend is clogged

              today i have checked whats happend if i set the current from the extruder to 80 % then i have moved the wiring from the three Z-Axis to the Duet Board (bevore was two motors on the duet and the third was on duex ) and the extruder to the duex Board .... without success my printhead always make a pause between the layer change 😞

                Do you do a retract on layer change? If so is your retract /un-retract speed too slow?

                  hi,

                  thanks for this hint i have tested with 40mm/s and now i will test higher values.
                  PA seems to be a BIG secret for me...

                    the same result as every print.... but this does me not wonder my printer makes this ugly seam because i have tried without retract before too.I'm clueless what i should try as next....

                      PA doesn't normally cause a pause on layer change (although an M572 on every layer change might). Suggest you turn off PA for now and fix the pause on layer change (either too slow Z speed or too slow retraction). Then introduce PA but rather than changing it every layer via the gcode, simply change the values "on the fly" by entering the commands through the console.

                        i think i have two problems ... one of it is prusaslicer they deliver only crap and i don't know why because the settings are the same as s3d or ideamaker ... so i will try in the next days to understand how the phyton scripts from the monster PA threat working.
                        so far thanks to all who tryed to help me on this problem!!!
