UM2: Merkwürdige Linien im ersten Layer


Recommended Posts

Posted · UM2: Merkwürdige Linien im ersten Layer


ich habe schon länger nen Ultimaker 2, aber seid kurzem fällt mir auf das im ersten Layer so komische Linien gedruckt werden, bei PLA und bei ABS.

So als ob sich die Linien sich überlappen und an den Überlappungen kleine "Wulste" entstehen. Was kann der Grund dafür sein.

Ich benutze in diesem Fall die Standard PLA Einstellung und das Grau Silberne PLA von Ultimaker.

    Ich vermute, dass der Abstand zwischen Düse und Druckbett zu klein ist und das Material deswegen ungleichmäßig extrudiert wird.

    Bed Leveling sollte da Abhilfe schaffen.

    Ich würde sagen, dass Cura zuerst den Perimeter des ganzen Teils, dann den Perimeter der Bohrung und dann die Füllung dazwischen druckt. Leider gibt es keine Retraction zwischen den Perimetern, so dass eine feine Linie Material liegen bleibt. Die Füllung gleicht das zwar beinahe wieder aus aber eben nur beinahe.

    Falls Du die Linie nicht haben willst, sprich Retraction auf dem ersten Layer aktivieren, so gibt es im Moment nur das http://wiki.ultimaker.com/CuraPlugin:_RetractWhileCombing dazu.

      • 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 5.3.0-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.
