 ## Motivation
 I was looking at the ERCF MMU for several month now. What always kept me from starting the project were the discussions about issues and problems with  filament tip forming. Suddenly a new company showed us how they do it quite reliable. They just cut the filament. Further motivated and inspired by the design of @pure100kim who has built the [ERCF_Filament_Cutting_MOD](https://github.com/pure100kim/ERCF_Filament_Cutting_MOD) I started to build my own version of it.
