Applying two different input shapers on two axes has certain downsides

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, thanks for the explanation.

@dc42 - this release seems to be breaking my Nozzle Heater on the 1LC.

@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.

BoA

@damaged_goods I use Prusa Slicer - it works perfectly fine.

For what printer and what Duet board? Duet3d Mini5 on Prusa MK3?

Hi,

I have a MB6HC with a SBC-Rasbarry Pi 4.

I am using the apt-get update / apt-get upgrade. It says that nothing to upgrade. But when I try the M115 command it says firmware 3.2.2

Do I do something wrong?

I have been following the documentation.

damaged_goods

@boa Thank you,

damaged_goods

@zapta It's a custom built very large printer with a duet 3 MB6HC.

@schickfus can you open a separate thread for your issue please

Schickfus

@jay_s_uk ok

@damaged_goods I use SuperSlicer. https://github.com/supermerill/SuperSlicer/releases

It has thumbnails compatible with the PanelDue.

Thumbnail

Anyone know how to get thumbnail generation in Cura?

oliof

@tfjield Install the RRF plugin for Cura.

@dc42 @oliof
I installed it, and all I see is that it's asking me to link my printer...

Does this require me to send the file to the printer directly? Or can I just save the gcode with the image embedded?

Phaedrux

@tfjield That plugin allows you to send the gcode files directly to the printer, yes, and also will embed the thumbnail. I believe you can also save the gcode file locally.

oliof

@tfjield it will ask you to link to a printer, but after you sliced a file you will see a little caret on the blue "Send to ..." button where you can choose to save the file locally.
