UMO+ ligne horizontale

Recommended Posts

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.
