Hallo . bei meinen Ultimaker 2.0 ; ( der schon fast 600st hat)

kam heute rauch aus Extruder, warum?

könnte das was mit dem Fillament zu tun haben ?

    Hat es dir das Zimmer zugenebelt, oder waren es nur ein paar kleine Rauchschwaden?

    Vermutlich hat sich etwas PLA am Rand der Düse gesammelt. Könnte zum Beispiel sein, dass ein kleineres Stück eines Druckobjekts abgebrochen ist und sich an der Düse festgesetzt hat.

    Dieses PLA köchelt dann schön vor sich hin, und löst sich irgendwann in Rauch auf.

    Es könnte auch sein, dass dein Hotend undicht ist, und PLA zwischen der Düse und dem PEEK Isolator hervorquillt, welches dann ebenfalls mit der Zeit verkohlt. Falls dem so ist, dann solltest du das Problem beheben. Beim UM2 kann ich dir damit allerdings nicht helfen, da muss jemand anders einspringen.

    Problematisch wird es, wenn es stark raucht, und vor allem stinkt. PLA stinkt ja nicht wirklich (und ist auch kaum gesundheitsschädigend), wenn es verkohlt. Das würde dann auf einen Kurzschluss bei der Heizkartusche hindeuten.

      • 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.
