I am using kicad 7 but with kibot. I will post the pipeline tomorrow here as another comment as I can't do it via mobile.

Edit: I will probably do a complete write up on my blog as I changed a few things between 6 and 7. Should be posting it within a week at https://sschueller.github.io/

When you post it, also submit it as a story on HN.

Here is my write up: https://news.ycombinator.com/item?id=35922207
