      Hi,

      today i used input shaping for the first time on a very fragile machine (modix big meter), so far everything worked well thanks to the excellent documentation and i ended up with a good ZVDD compensation at 22hz.

      I still have to do some before and after testing however i was a bit suprised by how quick the testing moves were done.

      I followed the input shaper plugin and it suggested one x and one y move, which surprised me a bit.
      from what i can see from klipper input shaping its a much longer procedure with all kinds of testmoves in all directions, with different speeds and differently long moves.

      I wonder if I should add more moves or if I missed a step somewhere, or is there a library of testmoves out there somewhere?

      Can someone shed some light on how the input shaper procedure is supposed to be done?

      Cheers
      F.

        @sungod3k nope, that's correct. RRF does one move in X and Y at the maximum speeds etc set in config.g.
        22Hz seems a little low however

          it s huge 1x1x1 meter machine, so it might not respomd on the normal frequencies

            @sungod3k can you post your graphs? would be curious to see.

            IIRC, anything below 20Hz in klipper is discarded
