The QUBD extruders are similar, and so are the extruders on the old Makerbots.
Cannot be jammed? Hmmmm. As I recall, the QUBD and the Makerbot extruders were jammed most of the time.

Did no one else notice the huge blower pointed at the threaded part of the hot end?
I dont like how its mounted. The heater cartridge is right near the mounting point soaking heat into the printer and the nozzle. Not really the best idea but if it works then good job.

yeah ... not exactly a speed daemon, 500mm/min only equates to 8.3mm/sec which in printing terms isn't exactly what i would call fast personally i'm running between 60mm/sec and 90mm/sec and others run a lot faster
the only reason that hotend "works" is simply down to the ptfe tubing inside the stainless tube and you'll be getting a huge meltzone so i wouldn't expect retraction to be very helpfull

But stratasys(dimention) melting zone as twice as longer and retract works.
I want to try their nozzles.
BTW what hotends do you speed up to 60-90mm/sec?
