Prusa MMU2 Tuning and Optimization

The attached PDF contains a summery of the steps I took to get my Prusa MK3S MMU2S printer running with almost no interventions. Start with the PDF and follow the steps and modificaitons. The real goal of this process is to eliminate any friction points for the filament. In doing so I converted all of the filament paths to connect with M10 passthrough fittings. Thought it would be useful to share.

Also there is one original part included. The wall mount for the M10.

Good Luck and let me know if there is anything that should be added. Happy to edit this post and process to help others.

1) Checking the filament paths to make sure there is as little friction as possible. From the spool to the extruder here are the steps I took.
