Prusa MMU2 selector and filament path improvements
thingiverse
I conducted extensive research on the filament path to overcome persistent sticking issues. This redesign encompasses a new path for the filament through the selector, effectively replacing the PFTE front, the selector itself, and the blade holder. The revamped path incorporates improved funnels to guide twisted or curved filaments with greater ease, as well as a reduced distance between the PFTE front and the selector. Additionally, I strongly recommend removing any burrs and strings using a small drill for optimal performance. Notably, the blade has been deepened and its edge made more aggressive against the PFTE front. However, since this feature is not currently utilized by the firmware, it's not essential to install the blade at present. The licensing for this project has been inherited from the Prusa GitHub repository.
