2in1 Hotend Y Adapter "23" - Dual Extruder one Hotend (Remix)
Description
# **UPDATE I don't know why the adapter STL was missing at all, now it's complete! 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 <code>#define EXTRUDERS 2</code> 2. activate <code>#define SINGLENOZZLE</code> 3. activate <code>#define E1_DRIVER_TYPE </code> with the driver of your choice 4. activate <code>#define DISTINCT_E_FACTORS </code> 5. add E1 to: > * <code>#define DEFAULT_AXIS_STEPS_PER_UNIT { 80, 80, 400, 95, 95 }</code> > * <code>#define DEFAULT_MAX_FEEDRATE { 400, 400, 20, 120, 120 } </code> > * <code>#define DEFAULT_MAX_ACCELERATION { 1000, 1000, 100, 5000, 5000 }</code> *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.
