  1. Working really well so far Printed several test cubes and a couple of real items so far and it is working very well. Tempted to purchase some additional nozzles for finer prints. I am using this on an M505 I3 Prusa RepRap. I had to cut out part of the metal bracket on my extruder carriage to account for the filament button that sticks out slightly. But that is not a problem with the extruder but merely my setup.I had to make some adjustments to my firmware of course but it seems like setting Marlin on 16…

  2. Finally!In the process of building my first 3D printer and learning as I go (I’m good with electronics, but not especially experienced with mechanisms), I’d tried probably four or five extruder setups, only to have all of them jam irretrievably sooner or later.In desperation, I bought this one, since it was a complete, stick-it-on-the-gantry-and-wire-it-up solution.It has worked beautifully, and saved my 3D printer from a completely undeserved defenestration…
