Material Switching Bowden feeder
Description
Important Notice I Have Exams These Days And Experiments On This Are Delayed By Now. I'Ll Try To Make A Video Of It Working As Soon As I Finish Them -------------------------------- "Y" Joint To Feed A Single Nozzle With Two Different Filaments. With A Bit Of Firmware Tweaking It Is Possible To Extrude Multiple Colours/Materials With One Nozzle. Material Switching Is Still Experimental, And Needs A Lot Of Tweaking. Cold Retraction Is Needed To Properly Clean The Tip, And Distances Need To Be Calibrated Or You May End Up Trying To Put Two Filaments In The Same Tubing Section. It Can Be Also A Bit Time-Consuming. Anyway This Has Potential To Be The Grandfather Of The Multicolour Printer Of The Future. The Presented Setting Has Been Tested Successfully On A Prusa Mendel I2 With A Customized Firmware, An E3D Nozzle And Two Jonaskuehling Extruders, Generating The Gcode With Kisslicer.
