kleiner Lüfter Grund für Unterextrusion?


Recommended Posts

Posted · kleiner Lüfter Grund für Unterextrusion?


habe nach ca. 30 Teilen keine Chance überhaupt noch etwas zu drucken.

Bin gerade draufgekommen das der kleine Lüfter kaputt ist.

Denke das dadurch die Reibung im "Cool-End" zu hoch wird und so Drucken unmöglich wird. Bin ich da richtig mit meiner Vermutung?

Der Lüfter hat die Abmaße 25x25x8mm. Muss ich für das Beschaffen des Ersatzteil noch etwas bezüglich Anschlussstrom etc. beachten?

Vielen Dank im Voraus!

LG Georg

    Wenn dieser Lüfter nicht arbeitet, dann ist zuverlässiges drucken kaum noch möglich. Zudem wird das ColdEnd (PTFE) recht schnell überhitzen und unbrauchbar werden. Eventuell ist aber nur der Lüfter-Anschluß oberhalb des Druckkopfs in dem schwarzen Gewebeschlauch defekt, dies solltest Du zuvor einmal überprüfen. Es kommt auch gelegentlich vor, das die kleinen Verbindungsstecker in ihren Gehäusen nicht korrekt sitzen.

    Der originale Lüfter müsste ein Typenschild besitzen, also zuvor nach der Modell-Nummer suchen und Informationen googlen. Denn es müssen neben den offensichtlichen Abmessungen auch die Leistungsdaten, sowie die vorgegebene Anschluß-Spannung übereinstimmen.

    da ich das selbst mal gefragt hatte, hier der Link: http://umforum.ultimaker.com/index.php?/topic/8918-um2-kleiner-l%C3%BCfter-hinten-am-extruder-daten/

    Leider habe ich keine weiteren Daten zum Luftdurchsatz gefunden, aber bei 5V und den Größenabmessungen gibt es auch nicht so viel Auswahl.

      • 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.
