Ultimaker 2+ Pulleys werden Locker auf den Wellen


Recommended Posts

Posted · Ultimaker 2+ Pulleys werden Locker auf den Wellen

Habe, meinen Ultimaker 2+ neue Lager Keramik Hybrid Lager ,neue Wellen in H8,

Neue Pulley Keilriemen und Gleitblock und Druckkopf in Aluminium gegönnt.


Achsen und so weiter eingestellt und auch Keilriemen.


Jetzt zum Problem.

Es scheint das auf diesen Wellen die Pulley nicht lange halten. Ich konnte es nur mit Jraft aufwand und inbus schlüssel anziehen das es hält.

Habt ihr da einen Tipp.


Kann es auch sein das Keilriemen zu Streng ist und deshalb sich die Pulleys lockern?

    Dass man bei den Pulleys die Madenschraube extrem fest anziehen muss damit sie hält, ist auch bei den Originalteilen so. Ein normaler Inbusschlüssel kann sich da schon etwas biegen. Falls es trotzdem nicht hält, dann liegt es wohl an deinen Teilen. Ich würde dann doch eher zu den Originalteilen greifen, denn da kannst du dir sicher sein, dass es passt und funktioniert.

    nunja, eine Maden- aka. Stiftschraube festknallen, bis der Sechskantschlüssel Funken schlägt ist leider DIY Style.


    Du kannst es theoretisch etwas besser machen.


    Die Riemenräder sollten nach Möglichkeit zwei Stiftschrauben (eine in 90° versetzt haben.)
    Die Schraubensicheung wäre Loctite 243.
    Die Wellen Nabensicherung dann Loctite 638.


    Viele Grüße

    Was man noch machen könnte, wenn sonst alles OK ist, sind die Standard-, Gewindestift/Madenschrauben zu tauschen und stattdessen DIN914 Madenschrauben zu verwenden.

    Habe ich so gemacht und habe keine Probleme, und das Problem das an den Wellen Macken entstehen, sodass sich die Pulleys oder die Wellen nicht mehr frei verschieben lassen, habe ich mit den Spitzen Madenschrauben auch nicht.

      • 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.
