Pause at height sur UM2+


Recommended Posts

Posted · Pause at height sur UM2+


J'utilise le plugin pause at height pour pouvoir inclure des écrous dans ma pièce imprimée.

Mon problème est que l'imprimante m'attend parfois plusieurs heures en pause car mes impressions sont longues et le filament fond et coule de la buse.

Lors de la reprise, j'ai donc un manque de matière sur quelques couches et mon impression est ratée.

J'ai essayé de mettre 0-20 ou 40mm de rétraction avant la pause, de faire un changement de matériau avant la reprise de la pause, mais rien n'y fait.

Auriez vous quelques conseils pour que ca se passe bien ?

    Avant de relancer l'impression lève le levier du feeder et pousse le filament à la main pour que ça extrude un peu, de cette manière tu es certain que tu ne vas pas sous extruder au début.

    Salut et merci pour vos réponse, j'avais pensé à extruder manuellement mais j'essaye d'avoir une procédure automatisée.

    On peut, dans le plugin demander une extrusion avant de reprendre, le problème et que suivant le temps de pause, la buse était bouillante et il fallait extruder une grande longueur avant que le PLA ne sorte plus liquide.

    J'ai résolu mon problème en programmant une extrusion avant reprise et en modifiant le Gcode afin que la buse refroidisse en attendant la fin de pause :

    J'ai remplacé :

    M0 ; Do the actual pause

    Par :

    M109 S30

    M0 ; Do the actual pause

    M109 S220

      • 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.
