Rostock Max Greg's Wade's Extruder Mod
thingiverse
Replace your "Steve's Extruder" with a Greg's. This is working GREAT for me, quiet, fast. 60mm/s retractions are no problem, probably could go faster but haven't tried... and so much quieter! Mounting bracket has standard 50mm holes and should fit anything. Two versions of the Greg's Wade v3 are included here. One is for use with a blddk-style hobbed sleeve, and the other for a standard hobbed bolt. Both are sized for 1.75mm filament. Here's a link to the blddk-style sleeve: http://store.makerstoolworks.com/extruders-and-parts/machined-hobb/
