    Help, Hot end enclosure seeping out molten filament

    Hi all,

    I bought my first 3D printer (Creality CR10) last week and printed a few nice small prints.
    Switched filament (from white to black), before trying to print one of the essential upgrades for the kit, but found a significant amount of melted white filament coming from inside of the box in the hot end.
    I've taken the case off of the hot end and seen a lot of filament that is just surrounding the hot end. See pictures attached:



    I've read that this is because of the connection between the filament feed tube and the hot end nozzleis not flush. I've tried following the guidelines, of losening the nozzle, before trying to retighten it (all whilst hot). But to no avail.

    Help anyone?

    First off you need to clean everything of molten plastic. Heat up to mild temp 150 or so and use a metal brush to clean up the mess as much as possible. Use also pliers and even metal rod (small diameter) to clean everything as much as possible.

    Then unscreaw everything and keep cleaning.

    Once everything is clean:

    Screw the nozzle head ALL THE WAY IN on the alu block.
    Unscrew the nozzle head half turn.
    Screw in ALL THE WAY IN the heatbreak part.
    Heat up to 210C
    Carefully screw the nozzle a bit.

    Everything should be flush now.
