      @axiom what version of the firmware are you running?

        It is the newest 3.5.4 on a duet 2 wifi board, the acelerator is a duet v 0.2

              @axiom I would suggest not worrying about input shaping in 3.5. it's been rewritten in 3.6 and performs a million times better than on 3.5.
              You could always try giving 3.6b2 a whirl or wait for 3.6b3

                @axiom change the shaper type to ZVDD or ZVDD or EI2 or EI3 and set the centre frequency between the two peaks.

                  @dc42 That's interesting, and how can I write that into the config?

                    @axiom

                    M593 P"zvd" F49.4
                    

                    Becomes

                    M593 P"zvdd" F49.4
                    

                    Or

                    M593 P"ei2" F49.4
                    

                    Or whatever else. Its really that simple. As DC42 says, you may want to tweak the centre frequency (F parameter) so that it better covers both of your peaks.

                    Basically those other shapers have a wider frequency range than ZVD. You'll see that using the shaper tool when you switch between them!

                      @engikeneer Thank you very much, but how do I enter the second frequency?

                        @axiom you don't. The shapers cover a frequency range, so if you pick one that covers a wider range and set it to be in the middle of the two frequencies, it should help both. You can't input shape different axes with different frequencies

                        In the second image you posted, you can see frequency range the ZVD shaper is filtering as a green dashed line. Play with the others in the plugin and see what works.
