      Does prusa slicer now allow per move jerk settings as well as acceleration? I didn't think so.

      The PrusaSlicer has its own jerk setting (mm/s), maximum acceleration (mm/s²) and maximum feed (mm/s)
      for each axis.

        Where? You mean in the machine limits?

          Yes, exactly.
          But it is clear that the upper limit is determined by the config.g.

            Thank you all for responding.
            I will not be able to check settings or respond back with said settings until late next week.

            Cheers

              Yes, I made those changes in PrusaSlicer.
              Are you suggesting that I make the changes in config.g?
              And if so, is that command M566?

              My current M566 is not labeled "jerk" so I just want to confirm.

              M566 X1500.00 Y1500.00 Z600.00 E120.00			; set maximum instantaneous speed changes (mm/min)
              
              M203 X12000.00 Y12000.00 Z600.00 E2100.00		; set maximum speeds (mm/min)
              
              M201 X1500.00 Y1500.00 Z500.00 E250.00			; set accelerations (mm/s^2)

                Yes, maximum instantaneous speed changes is often called jerk.

                  Got it. Do you have some recommendations from my current settings?

                    @davidewen Try these

                    M566 X1500.00 Y1500.00 Z600.00 E3000			; set maximum instantaneous speed changes (mm/min)
                     
                    M203 X12000.00 Y12000.00 Z600.00 E6000		; set maximum speeds (mm/min)
                     
                    M201 X1500.00 Y1500.00 Z500.00 E3000			; set accelerations (mm/s^2)

                      Thanks for the info. This has helped a lot. Seam is still there, but greatly improved.
                      I will play around with these settings to see if I can get it to almost perfect.

                      Cheers!

                        Have you tune pressure advance yet? That's the remaining piece of the puzzle.
