ATSG
Attention!!!
This Project is almost 1 Year old, and I can't maintain that alone. My hope was, that it would get more attention and more people would collaborate.
Therefore, I can only give limited help to anything.
They also have a Telegram Chat
Also I moved long ago to Klipper (Highly recommended, you can do this with any old PC, you don't need a Raspberry)
Here you can find a website that contains an installation guide and the download table
