    Hi! Sorry to say, but I found it hard to pull this nozzle out of the heatblock. By warming it up by torch it was possible to remove it. Usually You can pull it out with no effort. Now I discovered some dark material (propably filament) around the neck of the nozzle. Propably it acts as an insulation, because printing was impossible due blockage.
    Perhaps the nozzle leaked from the joint. Left in the picture is a not used nozzle. Can the leak be sealed?
