v2.6.0

Prerequisite

Klipper introduced some changes in the way resonance testing work that broke S&T. I had to make modifications to S&T in order to fix and support this, but this also means that you need to update Klipper : Please update Klipper to a version after Feb 17, 2024.

What's Changed

• More accurate damping ratio calculation by using the half-quadratic gain method, which should be more accurate than the half-power method used in previous S&T versions for higher damping ratio values (above 0.05).
• Fixed the bug introduced in the latest Klipper commits.
• The last point now also allows S&T to use the current machine square corner velocity value (or define your own) and the calculated damping ratio to further improve and personalize the results. You will probably notice some changes, but now the results should be more accurate to what will actually happen in your machine. For instance, using a higher SCV will cause more smoothing and result in lower acceleration values (this was not taken into account before). Moreover, the shaper recommendations are now calculated by taking into account your real damping ratio, and not the default value of 0.1 that was used before.
• Finally, you will now be able to define a maximum smoothing value that you want to allow for the shaper recommendations.

Documentation Changes

• Added a bunch of details about the LIS2DW chip to the documentation, since it's known to produce a lot of aliasing and can be a bit problematic.
• Changed and improved several parts of the documentation...
