###### VIBRATIONS AND SPEED OPTIMIZATIONS ######
################################################
# Written by Frix_x#0161 #
# @version: 2.1
# CHANGELOG:
# v2.1: allow decimal entries for speed and increment and added the E axis as an option to be neasured
# v2.0: added the possibility to measure mutliple axis
# v1.0: first speed and vibrations optimization macro
### What is it ? ###
# This macro helps you to identify the speed settings that exacerbate the vibrations of the machine (ie. where the frame resonate badly).
# It also helps to find the clean speed ranges where the machine is silent.
# I had some strong vibrations at very specific speeds on my machine (52mm/s for example) and I wanted to find all these problematic speeds
# to avoid them in my slicer profile and finally get the silent machine I was dreaming!
# It works by moving the toolhead at different speed settings while recording the vibrations using the ADXL chip. Then the macro call a custom script
# to compute and find the best speed settings. The results can be found in your config folder using Fluidd/Mainsail file manager.
# The goal is to make it easy to set, share and use it.
# This macro is parametric and most of the values can be adjusted with their respective input parameters.
# It can be called without any parameters - in which case the default values would be used - or with any combination of parameters as desired.
# Usage:
# 1. DO YOUR INPUT SHAPER CALIBRATION FIRST !!! This macro should not be used before as it would be useless and the results invalid.
# 2. Call the VIBRATIONS_CALIBRATION macro with the speed range you want to measure (default 20 to 200mm/s with 2mm/s increment).
# Be carefull about the Z_HEIGHT variable that default to 20mm -> if your ADXL is under the nozzle, increase it to avoid a crash of the ADXL on the bed of the machine.
# 3. Wait for it to finish all the measurement and compute the graph. Then look at it in the results folder.
