About this 3D model

Remix - Thanks [.Solidoodle2](https://www.thingiverse.com/Solidoodle2) for the idea and good preparation. Remixed:=======* Bigger Pushfitting M10 * The Bowden can be deeper lowered. * In addition, it must be cut off at an appropriate angle.* no hard edges, round transition guide, so that the filament glides through better *u need only a second Extruder&Motor* *Marlin aktivate second E (E1) & mixed hotend* ## retraction length: (Must be fine-tuned per printer and hotend >120mm/s )* ca. 120mm (4,72 inch)* min Speed 80mm/s (faster be better. I recommend) ## Cutting PTFE with the help of the template ### Marlin 1.1.9 Change 1. define #define EXTRUDERS 22. activate #define SINGLENOZZLE3. activate #define E1_DRIVER_TYPE with the driver of your choice4. activate #define DISTINCT_E_FACTORS 5. add E1 to:> * #define DEFAULT_AXIS_STEPS_PER_UNIT { 80, 80, 400, 95, 95 } > * #define DEFAULT_MAX_FEEDRATE { 400, 400, 20, 120, 120 } > * #define DEFAULT_MAX_ACCELERATION { 1000, 1000, 100, 5000, 5000 } *Marlin can control up to four extruders* ### Slicer * Recommendation (straight for beginners) Slic3rPE* I use Cura 4 * Extruder zero offset to all sides* Retraction at Tool change length ca 120mm (4,72 inch)* Retraction speed at Tool change 80-120mm/s It is also possible to specify the retraction as start code for each extruder.
