Basics

A series of devices, which not only cut and swap filament, like the Prusa Multi Material Upgrade , but also thermally bond/splice the two strands
Thus it is less likely to jam
Otherwise it is similar to any other Filament Swapping Devices
Has 4 Filaments in Per Device
Only Uses 1.75mm Filament
Main Uses Are:
- Swapping filament colors
- Automatically Changing Filament Spools
- Swapping to a filament of a (roughly) similar temperature
MAY be able to swap to a filament with a much higher/lower melting point, but this is less reliable NEEDS MORE RESEARCH
Has gone through the following versions:
- Palette (1)
- Palette (1+)
- Palette 2
- Palette 2 Pro
- Palette 2s
- Palette 2s Pro

The hardware itself is proprietary, and CANVAS software also appears to be proprietary.

It would be useful to open-source this device - it is quite useful.

Mixing extruder support exists in Marlin - https://marlinfw.org/docs/gcode/M165.html. Functionality appears to be limited. [1]. Software integration needs to happen.
