I like know if other users have same problem when they have replace your extruder in this rostock 301. because I think this have a factory error.

The original nozzle is due to its structure more often clogged. The filament flow is easier to go backward, cool down and clog the tube, especially when printing a single color.

So our technic team redesigned it and released a new one:

Where did it clog? In the nozzle or PTFE tube? Can you unclog it with thimble?
What kind of filament, and what's the configuration, temp, nozzle diameter, retraction and so on?
