UM2 ne démarre plus....


Recommended Posts

Posted · UM2 ne démarre plus....

Hello tous.

Mon UM2 ne démarre plus, je pense que j'ai un probleme avec le bloc d'alimentation.

En effet depuis quelques mois, elle "sifflait" un peut, ce qui n'est pas toujours bon signe, pour de l'electronique.

Cette alimentation etait pourtant branchée sur un onduleur 12Kva.:(

Ce matin, impossible de la mettre en route, la prise est pourtant bien alimentée.

Pouvez vous me confirmer que vous avez bien une led sur le bloc d'alimentation sensée s'allumer lorsque celui-ci est branché?

Et si oui, qui peut me dire sur lesquels des picots de la fiche je dois verifier la présence d'une tension?

    Oui tu doit avoir une led bleue sur le bloc alim. Même si l'imprimante n'est pas connectée.

    Quand tu prends la fiche face à toi avec le coté en plastique plat vers le bas tu dois avoir les deux bornes de gauche= 0Volts et les deux bornes de droite = 24Volts

    utilise le cerclage comme référence de masse.

    Laisse le bloc débranché une petite heure. il peut y avoir des fusible autocicatrisants dans ce type d'alimentation. change le cordon du 230V on ne sait jamais.

    prix du bloc: une centaine d'Euros :(

    Je viens de voir qu'il y'a le symbole de la fiche qui est dessiné sur l'alimentation ^^

    Si tu es joueur tu peux l'ouvrir et checker si tu ne voit pas un composant brulé.

    IL y'a FS1 à l'entrée (petit cube noir) qui est un fusible 5A

      • 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.
