Pb de sur extrusion (boursouflures)


Recommended Posts

Posted (edited) · Pb de sur extrusion (boursouflures)


Malgré toutes mes recherches je n'arrive pas à résoudre d'impression. Que j'imprime du PLA, couche de 0.2mm à 200° ou 220°, un plateau à 40° ou à 60°, j'ai toujours le même problème. J'ai calibré l'extruder mais rien ne change. Que j'imprime à 15mm/s ou plus, c'est toujours pareil. Je Slice avec Cura 4.8 et 4.13 le problème est identique. Je viens de changer la buse et hotend complet aujourd'hui et j'ai ce résultat.

Avez-vous une piste s'il vous plaît ?

Pour information, la deuxième couche est mieux mais la troisième couche est parfaite.

Merci de votre aide.



I've been looking into this and can't figure out how to print. I've been printing PLA, 0.2mm layer at 200° or 220°, a 40° or 60° plate, I still have the same problem. I have calibrated the extruder but nothing changes. I have calibrated the extruder but nothing changes, whether I print at 15mm/s or more, it's still the same. I Slice with Cura 4.8 and 4.13 the problem is the same. I have just changed the nozzle and full hotend today and I have this result.

Do you have a clue please?

For information, the second coat is better but the third coat is perfect.

Thank you for your help.

    Mauvaise calibration du plateau, à refaire.

    Calibration du plateau ?? bonjour, si vous pensez à la hauteur entre la buse et le plateau, j'ai réglé le "Home" au jeu de cale à 0,02mm.

    La calibration du plateau, ce n'est pas d'avoir la même valeur entre la buse et le plateau partout, c'est d'avoir la bonne distance entre la buse et le plateau partout.

    Trop proche, il y aura trop de filament extrudé pour le volume à remplir la première couche (sur extrusion) et symptomatiquement les couches suivantes seront généralement bien.

    Trop éloignée, il n'y aura pas assez de filament extrudé pour le volume à remplir et les couches suivantes ne seront pas plus belles (sous extrusion).

    0.02mm semble petit

      • 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.
