Suggestion: M593 Input Shaping Calibration Tower Slicer G-Code

When using the ringing_tower.stl method to calibrate Input Shaping, the following code is recommended:

M593 F{(layer_num < 2 ? 0 : 15 + 45.0 * (layer_num - 2) / 297)} ; Hz Input Shaping Test

While this does work, it causes the Input Shaping value to change over the entire model with a set value only showing up on a single line. Picking the "best' layer is very difficult.

I instead used this:

{if (layer_num - 2) % 25 == 0}
; Layer {layer_num} ({layer_z}mm)
M593 F{30 + 2 * (layer_num - 2) / 25}
{endif}

This sets the value for the entire tier instead, giving ~5mm of model to analyze and compare against the other layers. In my case I found values below 30 were just, well bad, so I started at 30 and went up to 52 in intervals of 2. Once I got a range that looked "best" then I could print the model again with better refinement.

This was done with an if instead of inline in order to allow multiple settings - for instance different ranges for the X and Y.

Start by locating the documentation section for the ringing_tower.stl Input Shaping calibration method and its current M593 example. Compare the proposed tier-based example with the surrounding instructions; done means the calibration guidance explains how to evaluate larger constant-value tiers and supports the multiple-settings context described in the issue.
