Now I have an Ultimaker 2*

how is the extruder working out?
First impression is really good - look at the video. It’s printing at 100mm/sec (infill)… And I didn’t even startet tinkering with it.
Extruder looks very robust. Its a bit louder than the stock one. And you now have a nema motor hanging outside your stylish Ulrtimaker 2
