Frequency Testing

This will allow you to test a specific frequency that you hear when you do your resonance testing in Klipper and potentially track down where extra peaks are coming from. If something is rattling at a specific frequency, you can specify that frequency and feel around the printer until you track it down.

Code was adopted by zifnab from somewhere in Klipper.

Usage

You have to have [resonance_holder] in your printer.cfg.

The command is HOLD_RESONANCE AXIS=<axis> FREQ=int SECONDS=<seconds>

We want to buy magnetic letters to teach French at home during the COVID-19 crisis.
I was wondering what is the optimal bag of letters to be able to *write* French words.

This script implements two ways of estimating this, *optimal bag of letters*:
- Per word max occurrence of each letters (ensure the bare minimum to write any single word of the dictionary [1])
- Statistical occurrence of letters (biased as words frequency is strongly dependent of the context [2])

This works in a python 3.6 environment with bokeh and flask installed. To use this you need the following directory structure:

app/
 - templates/
   - hello.html
 - bokeh-slider.py
 - hello.py

After that you need to open two terminals at app/, in the first one you need to run the bokeh server with the command:

git ls-tree -r --name-only HEAD | while read filename; do
  echo "$(git log -1 --format="%ad" --date=iso -- $filename) $filename"
done | sort
