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 2
2. activate #define SINGLENOZZLE
3. activate #define E1_DRIVER_TYPE with the driver of your choice
4. 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.
