-###### INPUT SHAPER KLIPPAIN WORKFLOW ######
-############################################
-# Written by Frix_x#0161 #

-# This module functions as a plugin within Klipper, aimed at enhancing printer diagnostics. It serves multiple purposes:
-# 1. Diagnosing and pinpointing vibration sources in the printer.
-# 2. Conducting standard axis input shaper tests on the XY axes to determine the optimal input shaper filter.
-# 3. Executing a specialized half-axis test for CoreXY printers to analyze and compare the frequency profiles of individual belts.
