Basic Information: Printer Model: Ender 3 Pro MCU / Printerboard: 4.2.7 Describe your issue: [shaper_calibrate_x] I’ve been manually configuring input shaper till now, and getting pretty decent results. I finally got an LIS2DW. It’s screwed to the X carriage, very securely, but I’m getting so…

That seems to be way to low tension on that particular belt. How is the heavier Y axis looking? LIS2DW is also prone to generate/catch much noise. So maybe you want to look for an ADXL345 instead.

I haven’t tried the Y axis yet, but it will be interesting to see what happens. I have tightened the belts a fair bit with almost identical results. The interesting thing to me on that graph is that according to it, there is zero amplitude in the X axis vibration.

I have a bit of an update. Definitely getting a little closer, but still seeing some odd stuff. Here is my latest shaper graph. [shaper_calibrate_x] Looking at other graphs I don’t see anyone else having any magnitude in those earlier frequencies. My printer is stiff as hell, all linear rails, …

What did you do to get a different graph? And then if you know how to install the Klipper from a different branch (e.g. via Kiauh), you can try this a bit different resonance testing algorithm and see if it produces different results for you: [image] A bit different resonance test D…

Compared to the original test, the above graph had 2 changes. First, I changed the usb c cable, since the results I was getting originally looked like it was possible that the data transfer was messed up. Secondly, I removed the EPA foam mat, and put the print directly on the shelf. I saw on anot…

[shaper_calibrate_x] Update after having a crack at smoothing the rails with knife sharpening stone, and placing back on foam pad. Slowly seems to be getting there. I do find that double peak interesting though, as well as that small bit of initial amplitude. I guess the rail is still binding som…
