Supprimer le tanguage de la tête


Recommended Posts

Posted · Supprimer le tanguage de la tête

Bonjour tout le monde,


J'ai une UM3 à dépanner, on m'explique que la tête, sur l'axe Y, tangue, ce qui provoque une déformation de la pièce, on voit bien que cette dernière n'est pas aussi droite et propre qu'une UM2+.


Et en effet, quand je manipule la tête, il y a un tangage (peut-être max 3° ?). La seule solution "valable" serait de diminuer fortement la vitesse de la machine pour récupérer une qualité d'impression raisonnable mais elle devient inexploitable à long terme.


J'essaie de réfléchir à un moyen de bloquer ce tangage mais vu le peu d'espaces disponible, je ne trouve pas de solutions... qui plus est que le clapet du ventilateur qui refroidit les buses est vraiment mal pensé, car il se détache facilement...


Réaliser une armature en Polycarbonate est une idée mais j'ai un doute sur l'efficacité...


Une autre idée ?

    déjà il faut trouver l'origine du tanguage.

    peut être une usure des paliers de la tête. a contrôler les jeux, 

    puis vérifier les axes, les bagues, roulements bref toutes les pièces en mouvement autout des axes X et Y.

    Je l'ai déjà trouvé ça, quand "j'empoigne" la tête, le tangage se produit. Ce n'est pas les axes, ni les bagues. C'est vraiment la tête, en particulier le trou ou se glisse la tige Y. Je suis étonné qu'Ultimaker n'aie pas prévu les "cylindres de coulissage" comme sur l'UM2+ pour la 3.

      • 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.
