Man I thought it was really cool what you did with the BoxTurtle’s when we were discussing what you did in the Armored Turtle discord. Its cool to see that you decided to open source everything so others can integrate your ideas into their printers/DIY kits instead of keeping your brilliant ideas closed.
As the developer of AFC-Klipper-Add-On (not AFC lite version 
since this does not work with AMS systems and was only created as a way to easily show spools on the U1 from my understanding), I will be happy to work with you to integrate some of your features into the plugin.
The two things I am most excited for is the mechanism for being able to purge while docked(would rather buy a kit instead of trying to invent something myself) and whatever you did to integrate the weight sensors into the trays for each lane. I am planning at some point to implement the ability to be able to change lanes asynchronously while docked, since a lot of toolchanger people outside the U1 world has been asking for this as well.
Anyways, feel free to reach out to me on discord(DM is fine same username) or send me a message here.
