Thews Drive - A Quick Release Flying Extruder for Delta printers
Description
Thews Made A New Extruder Drive Last Week. I'Ve Been Testing It And It Works Great! Best Part About This Drive Is The Quick Release And Being Able To Clean Off Filament Stuck In The Teeth Of The Spur Drive. The Whole Idea Of Suspending The Extruder Like That Is To Reduce The Length Of The Bowden Tube. Like This I Only Need 2.1Mm Retracts And I Don'T Get Any Blobbing Or Stringing Anymore. The Stepper Motor Is A Nema11 With A 27:1 Ratio Gearbox On It. Can Be Bought Here Or From Many Other Places: Http://Www.Omc-Stepperonline.Com/Gear-Ratio-271-Planetary-Gearbox-Dual-Shaft-Nema-11-Stepper-11Hs120674Dpg27-P-133.Html It Is Designed For 1.75Mm. I'Ve Just Drilled It Out And Put Ptfe To Suit 3Mm Filament And It Works Great. You Will Need To Put A Ptfe Liner Down Into The Filament Path For Smooth Operation. Fully Parametric Version Is Available On Onshape: Https://Cad.Onshape.Com/Documents/A3Cb8Db7B43254E191F1Baf0/W/6Af71Ddfbe1A12A952C95254/E/E7B23Ea0Ffae0B05Dfb65Ede
