klippain VS Print-Tuning

Regarding the MCU, it's actually 2 layers of boards_pins that are used in Klippain and I think you only looked at the second layer. You can get more info on this here: https://github.com/Frix-x/klippain/blob/main/docs/pinout.md

Most slicers allow passing the material type as a variable to your print start macro, you can then do logic based on that to determine if you want to soak, etc. Check out this repo for some ideas https://github.com/Frix-x/klippain

If you want to try it out or have a look, it's available here: https://github.com/Frix-x/klippain
