    @mike3d you can get Windows and Mac binaries of a fork of Prusa Slicer that supports QOI format from https://github.com/n8bot/PrusaSlicer/releases/tag/version_2.5.0-alpha0%2Bn8-release1. This version also has the option to retrieve the machine parameters from the Duet via http, if you have configured it for upload via http. Thanks to user @bot for implementing all of this.

    This is big news. Especially on the Duet integration part.

      Thanks @chrishamm, I was able to install the external input shaping plugin. Next will figure out how to use it.

      BTW, if most of the external plugins are not DSF specific, maybe remove DSF from their path on github?

          Is there a roadmap for RRF 3.5 available? What will be its focus?

            @ctilley79 Looking at the Github commit history, independent gcode streams seems to be the main feature being developed right now.

                You may need to reflash the wifi module. Try sending M997 S1 from the USB terminal.

                  @oliof I was hoping they would continue to work on input shaper implementation because I believe it still lags behind Klipper.

                    In what way? We are continuing work on the IS plugin to make it easier to use accelerometer data to tune IS.

                      Differences I see compared to Klipper right now:

                      • separate shaper frequency for each axis

                      • automatic resonance testing (with a accelerometer): Klipper firmware generates vibrations from lower to higher frequencies and tests each shaper for it‘s effectiveness at each frequency. The results and recommendations are then displayed in a graph. It also recommends maximum acceleration values.
                        Example:

                        @argo separate shaper per axis is not only unnecessary (because the supported shapers cover frequency ranges of up to 3:1), it is a bad idea because if you use different shape on different axes then the motion of the axes will no longer be synchronised during acceleration and deceleration. This will result in print artefacts, for example on corners that are not aligned with the axes.

                        I already said that we are continuing work on the input shaping plugin to make tuning IS easier.

                          How about a single input shaping that is direction dependent? That is, some interpolation for angles between X only and Y only?

                          (I don't know how input shaping works, just thinking loud).

                            @zapta Applying two different input shapers on two axes has certain downsides so we decided it would be better to support only a single input shaper for two axes to damp both ringing frequencies.

                            We have a first beta of a new input shaping plugin ready but we need to discuss a few more details internally before we eventually release it. I expect we'll publish it sometime this week.

                                I was thinking about a single input shaper but in direction of movement rather than direction of axises. Here is an example, let's say that you want to optimize a 45deg movement in a cartesian printer. You run the input shaping calibration process with moves in 45deg, analyze to determine frequencies and IS parameters, and then when you move in 45%, you use that input shaper. Now imagine that you test IS for direction in 45deg increment and when you move for example in direction of 50deg, you use some interpolation to determine the input shaping in that direction.

                                (I must say that I don't know how input shaping works but my understanding that it's some kind of modulation of the movement which can be applied for movements in any directions)

                                Does this make sense?

                                  @zapta given that the input shapers supported by RRF have effective bandwidths of up to 3:1, it's not necessary to do anything as complex as that.

                                  To get a 3:1 ratio of resonant frequencies on the X and Y axes, and assuming X and Y axes use belts of approximately equal width, length and tension, you would need a mass ratio of 9:1. That's higher than you are likely to get even in a large bed slinger.

                                        @dc42 Hey David. Thanks to you and others for all the work you are putting into reprap.
                                        As a Prusa user I am use to being spoon fed firmware and Slicer settings. Is there a Reprap Slicer that the community finds works best?
                                        Thanks again.
