Quick Guide to changing filament~

1. Have some paper to push away extruded filament.
2. When the MK3 jogs after a change it will spit out another inch, so I follow it with paper until it starts to move back down. Doing this has given great, repeatable results.
3. Use a tool like this to help changes→ https://www.printables.com/model/329171-filament-change-tool
