plantage en cours de mise à jour du firmware : UM2+ ne veut plus démarrer [résolu]


Recommended Posts

Posted (edited) · plantage en cours de mise à jour du firmware : UM2+ ne veut plus démarrer [résolu]

Ayant des soucis avec mon UM2+, après notamment la mise à jour du firmware avec la version 3.4, j'ai eu la mauvaise idée de vouloir remettre le firmware de la version 3.2.


Déjà en branchant l'imprimante avec le câble USB, elle s'allumait s'éteignait. J'ai changé de port USB de mon ordinateur, et lancé la mise à jour. Et attendu, attendu, attendu. J"ai fini par poser l'ordi et j'ai du bouger le câble...


Et depuis, l'imprimante ne veut plus rien savoir, n'ai plus reconnue par l'ordi et affiche des rayures, mais le bouton ne s'allume plus, et l'imprimante ne veut plus rien savoir....


Comment sauver mon imprimante ?

    En farfouillant un peu, avec le mot clé "bricked" j'ai trouvé la solution :

    en passant par cura 15.04, j'ai pu reconnaitre l'imprimante et réinstaller un firmware, puis faire la mise à jour dans cura 3.2


    J'ai fait un premier changement de filament : OK tout va bien.

    Je me suis dit que le problème venait de la lise à jour du firmware.


    Mais au deuxième changement : rebelote, le filament est poussé vers l'avant au lieu de sortir... 

    Ça reste un gros mystère pour moi.

    non non, j'ai bien vérifié.

    (c'était une piste à laquelle j'avais pensée au départ, d'où mes tentatives malheureuses de changer de version de firmware)


    Et si c'était le mauvais : le feeder tournerait à l'envers mais dans les deux sens non ?

      • 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.
