Hallo liebe Community,


ich beschäftige mich seit kurzem mit 3D-Druck auf dem Ultimaker3 Extended.

Ich würde mich sehr freuen, wenn jemand anhand der Bilder ein paar Fragen beantworten könnte.

1. Vor dem Druck werden links und rechts diese "Häufchen" gedruckt, sind das die s.g. Einzugstropfen?

2. Mit Printcore AA0.4 und (PLA) wird während der "Extrusion?" der Druckkopf hochgefahren. Das sieht irgendwie richtig aus. (1. Bild)

    Dies passiert bei BB0.4 (PVA) allerdings nicht und es bildet sich dieser Klumpen der im schlimmsten fall mit übers Druckbett gezogen wird. (Bilder 2-6)

    Ist das normal oder liegt ein Defekt vor? Muss ich eine gewisse Wartung vornehmen? Die Standarseinstellungen in Cura wurden nicht verändert.

3. Es passiert auch häufig, dass das PLA sich, bevor es die Druckebene erreicht, in der Luft "einrollt" und an der Düse kleben bleibt.

    Wie kann ich das verhindern?

    Ja der Drucker hat die aktuellste Firmware installiert und ich slice mit Cura 4.5.

    Auch beim normalen Druck mit PVA treten diese Haftungsprobleme auf (oder das "Einrollen" an der Düse).

    Ich hatte eher auf ein Problem der "Hardware" getippt, aber ich werde weiter testen.

    Nachdem ich hier im Forum bereits gesucht habe, hab ich, ohne Erfolg, mit verschiedenen Temperaturen und Lüfterdrehzahlen experimentiert.

    Ich versuche dann mal rauszufinden was Skirt oder Brim ist:)

      • 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.
