###### STANDARD INPUT_SHAPER CALIBRATIONS ######
################################################
# Written by Frix_x#0161 #
# @version: 1.3
# CHANGELOG:
# v1.3: added possibility to override the default parameters
# v1.2: added EXCITATE_AXIS_AT_FREQ to hold a specific excitating frequency on an axis and diagnose mechanical problems
# v1.1: added M400 to validate that the files are correctly saved to disk
# v1.0: first version of the automatic input shaper workflow
# -------------------------------------------------------------------------------------------------------------------------
# If you want to use it into your own config, please install it as a standalone macro as described in the
# installation section of this file: docs > features > is_workflow.md
# -------------------------------------------------------------------------------------------------------------------------
### What is it ? ###
# This macro helps you to configure the input shaper algorithm of Klipper by running the tests sequencially and calling an automatic script
# that generate the graphs, manage the files and so on. It's basically a fully automatic input shaper calibration workflow.
# Results can be found in your config folder using FLuidd/Maisail file manager.
# The goal is to make it easy to set, share and use it.
# Usage:
# 1. Call the AXES_SHAPER_CALIBRATION macro, wait for it to end and compute the graphs. Then look for the results in the results folder.
# 2. Call the BELTS_SHAPER_CALIBRATION macro, wait for it to end and compute the graphs. Then look for the results in the results folder.
# 3. If you find out some strange noise, you can use the EXCITATE_AXIS_AT_FREQ macro to diagnose the origin
