  Finally digging through my massive aliexpress basket and found out that this part is no longer available. I might have to print it if I can't find an alternative part.

  I've just been made aware of the following project: https://github.com/helgekeck/rome

  This could be a good starting position for the Klipper code needed for this project. What I'd need to implement is the logic for inverse stepper movement and servo control.

  I started designing the SecSavr Select inside the SecSavr Space file, so I've moved it into its own file and I am currently in the process of cleaning it up / adding groups before finishing the design. Below is an old gif I recorded. It shows what happens when the servo motor goes through 300 degrees of motion (out of 320).

  I plan to have a cheap microcontroller in charge of making sure that each loaded filament isn't clogged. I'm hoping that I can use a mouse encoder for this to detect both presence and movement. A Hall Effect based approach could also work. A command will then be sent to Klipper if there is an issue. Hopefully, it would be a change filament command so that the Select can load in a backup filament. The filament that had an issue would have a red LED associated with it, and taking it out and loading it back in will reset the error status.
