Düse verstopft

[Produktdesigner 2]

Hallo,

ich habe seit einigen Wochen eine Ultimaker3. Jetzt scheint nach wenigen Drucken die Düse des Filament verstopft zu sein. Wie kann man die reinigen?

cold pull zum reinigen.

use original filament when printing.

use standard profiles, not high temp, not high speed.

never mix abs / pla in same core.

what filament are you printing?

Instructions to clean your print core with hot pulls and cold pulls are here. The AA core can be cleaned in the same manner, however, that is seldomly necessary.

You state that you think your nozzle is clogged. What makes you think that?

If there is a mixture of Nylon and PLA in your print core, manually set the temperature to 260, and press some Nylon through the print core. You can best do that directly from the top of your printhead, after removing the bowden tube. Instruction are in the document linked above. Make sure you put the print head in one of the corners, to prevent bending the shafts that suspend the printhead.

We advise to use different print cores for different materials, so flushing it is not necessary.

Agree @tomnagel. When you print with PLA and change to Nylon ( higher temp) then residue of PLA in the Core is cooked to carbon or chewing gum.. It sits there and makes problems for you.

Repeated cold pulls!
