Nema 14 Geared Extruder Rev 1.2

youmagine

This is a reworked design of our Nema14 geared extruder from Thingiverse (www.thingiverse.com/thing:153356) * All drawings are reworked, removing all "reprap" sources so they are 100% free of other licenses * The gear ratio has been changed to 10:45 instead of 10:43, and the gears are not compatible with rev 1.0 * The idler screw nut is now inside the body * Spring screws no longer require a nut holder, making it easier to open * An additional setscrew has been added at the stepper arm for future development (cable/fan holder) * Minor changes have been made All parts have been test printed with a 0.4mm nozzle This extruder uses the same inserts as the Nano Extruder, except for the bowden insert which is not available The Groove Mount should work without an adapter and the brass insert for 1.75mm filament Although the body is capable of using 3mm filament, it is only designed to work with 1.75mm+brass insert ! (for flexible materials) If you try it anyway with 3mm and it will run don't hesitate to make a comment about it Beware that there are two versions, one with 40mm mounting holes and one with 50mm Running on the right setup it is possible to print with up to 400mm/s!
