Sorry for direct question: Is this this repo abandoned?

I see you have other GitHub activities, so you are still involved, but it seems this project is abandoned. Many milestones for v2.1, v2.2 and v3.0 are written down but not realized.
Any chance realizing those milestones at some point in the future? I would like to pick up this project and look into where I can help out, e.g. I already identified that I could (solder) jumpers for motor config MS1, MS2, MS3 to allow using other motors that the slightly outdated A4988 and TMC2208.

Hello!

I'm not actively engaged, but you are more than welcome to engage on anything you might like.

There is one issue related to drivers #54

We can absolutely make more releases 🙂

Great. How much time would you be willing to invest for discussion and code review? I can easily make some minor improvements, but for larger ones, I would need some feedback.
I would as a first step update the KiCAD files to V9 and add part numbers from LCSC/JLCPCB. With that, people have another sourcing possibility (and perhaps direct manufacturing possibilities).
