probleme de taille de print

Posted · probleme de taille de print

Bonjour a tous,


j'ai un souci de taille lors de mes impression. j'utilise un FLSUN sr.

tout mes print sont plus large en X et Y de 0.30mm.

j'ai calibrer la machine et l'extrudeur, le bed est cartographier.

les seuls print a la bonne taille sont les print en mode vase mais dés que je fait un print classique je suis a chaque fois a 0.3 de plus.

Avez vous une idée du problème.

    Calibration de l'imprimante...
    ...mais 1/10 ou 2/10 de mm d'écart dans les dimensions après impression n'a rien de spectaculaire ni de rédhibitoire au vu de la technique employée.

    Sachant que la précision dépend :
    De la taille de la buse (0.15..>..2mm)
    De la hauteur de couche (0.05 > 1 mm)
    Du filament employé (PLA, PETG, PA, etc.)
    De la température d'extrusion (si, si...)
    De la sous extrusion ou de la sur-extrusion (calibration du feeder)

    Le cube X/Y/Z est un bon outil de calibration.
    Sur une UM2 ce cube de 20x20x20 fera en X/Y/Z : 20.18/20.11/19.98 en PETG/FC, buse de 0.4 couche de 0.2 et ça me va.

    et les cotes du cube seront différentes en PLA et en ABS

    il faut le savoir avant de modéliser et prévoir dans quel sens on fera l'impression.

    c'est dur parfois d'expliquer a un néophyte qu'une imprimante n'est pas une photocopieuse, il ne faut pas juste appuyer sur un bouton.

      • 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.
