¶ FPS 2.1 Notes
These are settings for the FPS rev2.1. You can use the flashing instructions here preparing-the-boards, however change the settings for the board according to the parameters below. Revision 2.1 of the FPS had an STM32F072 MCU instead of a STM32G0B1. This revision of the FPS has a socket for a TMC stepstick with a large capacitor to support it, and includes breakout pins that can be used for additional input / outputs (including analog and digital switches for the filament path). In comparison to the STM32G0B1, it only lacks a USB Hub / port replicator.
¶ Case STLs
You can re-use the original AMS slide that came with the filament buffer PCB, and switch the spring with the stiffer one provided with the kit.

Here is a picture of it assembled (pictured is the v2.0, but the rev2.1 is very similar just the fuse location and motor location changed slightly):
¶ FPS as a CANBus bridge (USB -> CANBUS)
If you are using the fps rev2.1 as a CANBus bridge mode (default), here is the configuration for Klipper:
¶ FPS configuration as a pure CANBus device
If you are using the fps rev2.1 as a pure CANBus device, here is the Katapult (Canboot) configuration:
And here is the klipper configuration:
