UMO+ ligne horizontale

Bonjour,

Je continue d'apprivoiser mon UMO+....

Les pièces que j'imprime proviennent des banques d'objets en ligne.

Les résultats me conviennent...sauf que, il y a une ligne horizontale sur chaque print à env. 13 mm. du plateau...Comme si la machine "sautait' une ligne, les pièces sont même cassantes à cet endroit !

J'ai pas mal cherché...vérifié mon axe Z, pas de point dur...Là je sèche...

Merci d'avance de vos conseils !!

Mons

Salut mons1971,

J'ai exactement le même problème avec mon UMO+ J'ai déjà posté sur des forum mais jamais eu une aide concrète.. J'ai vérifié les diff axes et regraissé... Le problème se répète avec différents paramètre d'impression et à chaque fois situé à la même hauteur. C'est clairement un problème mécanique d'après moi, je pense pour le moment que c'est le roulement à bille qui pose problème mais je ne suis pas sur à 100%...

Voici un lien vers dropbox ou vous pourrez voir mes impressions ( sur une photo j'ai aligné mes print ou on voit clairement les lignes au même niv .. )

    Hep,

    Y a quand même quelques pistes dans ce sujet (merci Fab). Donc pour toi aussi ca peut être interessant:

     

    The third theory I have (these are all things that happen to people all the time on this forum) seems to me the most likely and possibly the most difficult to prove - it's that there is something sticky or wrong with the Z axis where it moves a little bit less than it is supposed to (say .19mm instead of .2mm on each layer) and then suddenly it finally catches up and drops 2mm all at once. Something like this. Because something is sticky maybe in the Z axis. You can test this by pushing the bed up and down and trying to feel for a bad spot. You can visually inspec the Z screw - also look for it warping. But the best test is to print a few different parts - preferably a 10mm square tower that goes the same height as the print you already printed to see if there is a gap layer. Then print another one 15mm square to see if the height is *still* the same. If 3 out of 3 prints hafe the same problem at THE EXACT SAME HEIGHT and the 3 prints are all different sizes (different amounts of material on each layer) then the problem must be related to Z screw or Z nut, or Z bars and you can have Ultimaker send you new ones. It might be as simple as adding some grease to the Z screw (in the green plastic container) and some light oil to the z rods.

      • 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.
