Défauts divers et variés

Ces derniers temps les trucs qui m'embêtent le plus, ce sont les défauts de paroi.


La seule explication que je voie, c'est que j'ai monté l'UMO+ sur des caoutchoucs qui la font chavirer à chaque accélération, mais elle bouge pourtant dans son ensemble.

C'est vraiment un problème non linéaire et j'ai l'impression que ça n'arrive qu'à moi !

Pour finir, j'ai du oozing en essayant de pas imprimer trop chaud alors je me demandais quels paramètres de rétractation mettre et s'il faut les faire varier selon les autres paramètres, parce qu'ailleurs il y a de tout niveau valeurs !

Merciii :D

    Tu imprimes à quelle vitesse?

    Le fait de mettre ton imprimante sur des caoutchouc n'a pas d'impactes sur la qualité d'impression

    Niveau retract les valeurs par défaut sont bonne la plupart du temps, tu as peut être un probleme au niveau des esteps? Ca sur extrude tout le temps?

    Là c'était 30mm/s, 0.2mm de hauteur de couche et 200°C.

    Ok cool, bonne nouvelle.

    Ok pour la rétract (c'est bien 6.5mm et 25mm/s ?)... je n'ai pas touché aux esteps :/ Comment ça, sur-extruder ?

    Sinon une photo où on voit mieux le problème de protubérance :


    Sinon j'ai réimprimé 30mm/s, 0.2mm, 185°C et rétractation à 6.5mm et 25mm/s, et j'ai toujours ces lignes qui sortent comme sur la 2eme photo... c'est dommage on voit pas bien. Ça me fait juste une face très striée. Mais j'ai moins de oozing et les faces sont un peu plus droites (droites c'est dans l'ensemble perpendiculaires au plateau, mais c'est différent des stries...)

    Même ceci ne m'aide pas...


    -C'est du Colorfabb.

    -Calibration de PID à faire ?

    -"if the print bed wobbles or vibrates while printing, this can cause the nozzle position to vary" qu'en penses-tu Didier ?

    "Z-axis threaded rod that is not being positioned properly. For example, due to backlash issues or poor motor controller micro-stepping settings"


    Pourquoi j'ai toujours des problèmes incompréhensibles ? :angry:

      • 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.
