This is a pintograph simulator inspired by Alfred Hoehn’s machines.
See it in action on https://michaldudak.github.io/pintograph/demo. This page shows a couple of examples that can be a starting point for your own setups.
I am working on an online editor that will allow creating drawings without writing a single line of code. However, it is not ready to be shared yet.
Kudos to Fran McConville for a pintograph description and a spreadsheet with calculations. I made several changes to the original calculation methods but it was a huge help for me.
The multi-wheel drawing machine was inspired by Robert Balke Zeichenmaschinen.
