      @dc42 said in RRF 3.4 input shaping preview available:

      @skrotz @jenpet I've put new binaries at https://www.dropbox.com/sh/ja08b7qdzsl8kjc/AAAwUbkN2XJvurq5CuQTgx5Wa?dl=0.

      I just tested lates bin. - no clunking and nothing suspicious when printing
      Test print done :speed 200mm/s, accel6000mm/s2 . PA 0.022
      print sequence from bottom to top:
      M593 P"none"
      M593 P"ei2" F62.7
      M593 P"ei3" F62.7
      M593 P"zvdd" F62.7
      M593 P"zvd" F62.7
      I think best result with ei3 , second zvd.
      First print where i could use zvd without any problems

      There still problem with DSF compatibility(???)

      Print status is 100% right away in DWC and PanelDue

        @dc42 I have lowered the PA value to 0.04 from 0.08 and now it looks better. I tried the same thing a few days ago but there was no inprovement. I think is was my mistake, sorry. Thank you for support.

          @jenpet thanks. Your previous report was very useful because of the reported step errors, and led me to fix a bug.

            @cadetc thanks. We are looking to release 3.4beta2 tomorrow, including the updated DSF.

              @dc42 I did a quick print with this latest firmware (PA 0.12, ei2 input shaping enabled as per usual) and can't say I see a significant difference between this firmware and the previous one on my print, although I'd swear that the previous one still had a tiny bit of "clunkiness" and this one seemed completely normal with no hint of a clunk whatsoever. No hiccups or errors in the M122 report. Like the just previous firmware, I don't see extrusion blobs or zits like were happening before -- I'll need to do some comparison prints with RRF 3.3 and this firmware to see if the minor extrusion issues I feel are present are different from RRF 3.3 or not. All in all, great progress though, and certainly seems ready for more people to start doing prints and comparisons with RRF 3.3 and testing input shaping. Very exciting.

              RepRapFirmware for Duet 2 WiFi/Ethernet version 3.4.0beta2-inputshaping (2021-08-02 19:33:23) running on Duet WiFi 1.02 or later + DueX5

              UPDATE: I did a baseline print with RRF 3.3 to compare with (DAA enabled at 41hz, PA 0.12), and the minor extrusion issues I was seeing in the latest 3.4 print are there as well in the 3.3 print.. it seems like something that could be improved on but it's not introduced by 3.4. So this latest 3.4 seems quite good to go.

                @dc42 thanks for the new release. It seems that is running good, you should call the next beta "clunk free".

                However i noticed i can't stop during mid-print because the firmware goes to status "generic.status.cancelling" when cancel button is pressed. From there i can't press the cancel anymore and the printer won't start a new job

                      I wish to thank all who have tested the RRF input shaping previews. With your help, I believe I have the new step generation code working well including input shaping and pressure advance. This has given me the confidence to include the new code in RRF 3.4.0 beta 2 which we released today.

                      Please upgrade to that release, and start new threads for any issues you encounter with it.

                        @dc42 the two contour lines get thinner and thinner at the end so that there is a gap between them.
                        Now I try to lower PA value again.

                        If you mean the two perimeter lines, they are joined in the perimeter at the top, joined for part of the length of the perimeter on the right, and not joined at all in the perimeter at the bottom. The difference between top and bottom suggests to me that you have chosen an unfortunate wall thickness and the slicer has failed to ensure consistent infill by altering the extrusion widths - so that whether the perimeters are joined or not is very sensitive to small changes. I am assuming that the thickness of all three walls is supposed to be the same.

                        I also have problems with pressure advance and input shaping with de PA values I already got finetuned without input shaping.

                        Top one: input shapping ei3 @48Hz + PA 0.1 (orbiter extruder direct)

                        Bottom one: just input shapping and no PA

                        Both 100mm/sec, 6000mm/s2 acceleration

                        You can see corners are ok with the PA, and bulges with no PA...
