ABS material burnt into/on the nozzle - what to do?

Posted · ABS material burnt into/on the nozzle - what to do?

Hi,

we got a brand new Ultimaker2 and the first prints came out fine. But now I have a serious problem with burnt material on the nozzle.

During the print something went wrong and the ABS material went all over the nozzle and got burnt. There is still a non-burnt bit of ABS filament at the tip of the nozzle (while the rest has a burnt coating) (see picture).

Can anybody help me with this problem? Is there a method to celan it? (Step by step for dummies?). And how can I prevent problems like that?

Thanks in advance,

Tina

    Unscrew the four screws that holds the fan bracket to the head so you get full access to the nozzle (you can just let the fanbracket+fans dangle while you work. Try to keep it out of the rear fan and away from the heat though). Heat the nozzle up to about 100C, pick away the bits you can get off. Heat up to printing temp and get any stubborn bits. Acetone is pretty decent at dissolving ABS so that can also help (just remember that it's highly flammable).

    Some heat and patience should get rid of it.

    I recommend you just ignore it. But to clean it one method is to remove the nozzle and soak it in acetone for an hour and anything that doesn't wipe off after that I would burn off with a flame.

    But taking the nozzle out of the head is tricky and you can break the temp probe cable if you aren't careful. Sometimes the probe slides out easy (after removing the very skinny screw) but other times it's just stuck the hell in there and almost impossible to remove without drilling it out and destroying it.

      • UltiMaker Cura 5.3 stable released
        In this stable release, Cura 5.3 achieves yet another huge leap forward in 3D printing thanks to material interlocking! As well as introducing an expanded recommended print settings menu and lots of print quality improvements. Not to mention, a whole bunch of new printer profiles for non-UltiMaker printers!

      • Here it is. The new UltiMaker S7
        The UltiMaker S7 is built on the success of the UltiMaker S5 and its design decisions were heavily based on feedback from customers.
         
         
        So what’s new?
        The obvious change is the S7’s height. It now includes an integrated Air Manager. This filters the exhaust air of every print and also improves build temperature stability. To further enclose the build chamber the S7 only has one magnetically latched door.
         
        The build stack has also been completely redesigned. A PEI-coated flexible steel build plate makes a big difference to productivity. Not only do you not need tools to pop a printed part off. But we also don’t recommend using or adhesion structures for UltiMaker materials (except PC, because...it’s PC). Along with that, 4 pins and 25 magnets make it easy to replace the flex plate perfectly – even with one hand.
         
        The re-engineered print head has an inductive sensor which reduces noise when probing the build plate. This effectively makes it much harder to not achieve a perfect first layer, improving overall print success. We also reversed the front fan direction (fewer plastic hairs, less maintenance), made the print core door magnets stronger, and add a sensor that helps avoid flooding.
         

         
        The UltiMaker S7 also includes quality of life improvements:
        Reliable bed tilt compensation (no more thumbscrews) 2.4 and 5 GHz Wi-Fi A 1080p camera (mounted higher for a better view) Compatibility with 280+ Marketplace materials Compatibility with S5 project files (no reslicing needed) And a whole lot more  
        Curious to see the S7 in action?
        We’re hosting a free tech demo on February 7.
        It will be live and you can ask any questions to our CTO, Miguel Calvo.

      • UltiMaker Cura Alpha 🎄 Tree Support Spotlight 🎄
        Are you a fan of tree support, but dislike the removal process and the amount of filament it uses? Then we would like to invite you to try this special release of UltiMaker Cura. Brought to you by our special community contributor @thomasrahm
         
        We generated a special version of Cura 5.2 called 5.3.0 Alpha + Xmas. The only changes we introduced compared to UltiMaker Cura 5.2.1 are those which are needed for the new supports. So keep in mind, this is not a sneak peek for Cura 5.3 (there are some really cool new features coming up) but a spotlight release highlighting this new version of tree supports.
