Remix - Huge thanks to [.Solidoodle2](https://www.thingiverse.com/Solidoodle2) for the brilliant idea and meticulous preparation. Remixed: * Enlarged Pushfitting M10 * The Bowden can be lowered even deeper. * Additionally, it must be cut off at a suitable angle. * No hard edges, round transition guide, so that the filament glides through smoothly You will only need an additional Extruder & Motor. Activate second E (E1) and mixed hotend in Marlin. ## Retraction length: (Must be fine-tuned per printer and hotend for speeds greater than 120mm/s) Approximately 120mm (4.72 inches) Minimum Speed 80mm/s (faster is better, I recommend it) ## Cutting PTFE with the help of a template ### Marlin 1.1.9 Changes 1. Define #define EXTRUDERS 2. 2. Activate #define SINGLENOZZLE 3. Activate #define E1_DRIVER_TYPE with your chosen driver. 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 (straightforward for beginners): Slic3rPE I use Cura 4. Extruder zero offset to all sides. Retraction at Tool change length approximately 120mm (4.72 inches). Retraction speed at Tool change 80-120mm/s It is also possible to specify the retraction as start code for each extruder.
