Тестим Input Shaping На DUET е (Reprap Firmeware)

[Technar]

С осями только напутал я в видосе этом. Сча протестил в бетте 6, работает лучше. И с датчиком другие частоты показывает, с ним точнее настроить можно

Можете показать, как выглядят результаты работы датчика?

Мне почему-то уведомления не приходят, случайно зашел и увидел вопрос. На данный момент видео пока готовится. В нем покажу

The current RRF documentation for M593 indicates that there's a single frequency selectable for the input shapers. Will this be changed to support independent frequencies and shapers per axis? Machines are far from iso-resonant, so choosing one frequency and shaper for both axis will yield a sub optimal result.

we're leaving the option open to support different input shapers per axis. However, this brings with it two potential problems. The first is that RAM usage would be increased; so we may not be able to support it on the Duet 2 series. The second is that if you use per-axis input shapers, then the print head will not longer follow exactly the path specified in the GCode. This generally doesn't matter for travel moves, but does for printing moves. This may be what the Klipper documentation refers to as "smoothing" when more complex input shapers are used.

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.
