Hello, i prefer to use Cura slicer it's powerfull and I think function that I propose can be adding in furure.

 

I wanna ask about motion shaper (input shaping (aka rrf input shaping), maybe it's have alredy exist (can't find it).

 

This technic reduse ringing on parts (first look i can find here) person "DigitalVision" modify gcode only and get nice and clean print, so cura slicer make the code. I'm not a mathematical or programmer maybe it's easy to add this technique to it.

    I'll admit that I don't know much about RRF, but from a cursory look Input Shaping is done mostly in the firmware. The only change that needs to be made (after calibration of the parameters) is adding an M593 gcode command to the start gcode snippet:

    At now yes, they add it in frimware, but they don't use close loop control system (like klipper). So i think it's can be adding in gcode by slicer it's can open this technique to 8 bit boards and so on. 

     

    In start it was only gcode modify: 

     

    The specific parameters for the correction above was f_n=40.4 Hz, zeta=0.

    I got these results without making any FW changes. I instead abused the motion planner by feeding it G-code that simulated the required motion profiles. I think the results look pretty interesting and this is probably worth pursuing further.

    I am afraid that doing this by preprocessing gcode (as opposed to inside the motion planner in the firmware), it will greatly increase the size of gcode files, which will have adverse effects on especially 8 bit boards.

    When are we going to get this update to the Ultimaker printers? I know that we can print slowly to improve quality, but also, the marlin update provides input shaping on all printers now.

    Same here. I look forward to the latest updates from ultimaker.

      • S-Line Firmware 8.3.0 was released Nov. 20th on the "Latest" firmware branch.
        (Sorry, was out of office when this released)

        This update is for...
        All UltiMaker S series  
        New features
         
        Temperature status. During print preparation, the temperatures of the print cores and build plate will be shown on the display. This gives a better indication of the progress and remaining wait time. Save log files in paused state. It is now possible to save the printer's log files to USB if the currently active print job is paused. Previously, the Dump logs to USB option was only enabled if the printer was in idle state. Confirm print removal via Digital Factory. If the printer is connected to the Digital Factory, it is now possible to confirm the removal of a previous print job via the Digital Factory interface. This is useful in situations where the build plate is clear, but the operator forgot to select Confirm removal on the printer’s display. Visit this page for more information about this feature.

      • Ultimaker Cura 5.6 stable released
        Cura now supports Method series printers!
         
        A year after the merger of Ultimaker and MakerBotQQ, we have unlocked the ability for users of our Method series printers to slice files using UltiMaker Cura. As of this release, users can find profiles for our Method and Method XL printers, as well as material profiles for ABS-R, ABS-CF, and RapidRinse. Meaning it’s now possible to use either Cura or the existing cloud-slicing software CloudPrint when printing with these printers or materials
