  1. It's sold with a robot assistant that handles changing filament and cleaning the plate after a print for you, then starts the new print. 😉
  2. Non, la tête est stable et ne bouge pas si je la secoue.
  3. Merci pour le liens. Ils sont en rupture de stocks sur les courroies! 😅 Heureusement que c'est pas trop grave non plus pour le moment. Je me dis que les poulies en métal ont peut-être moins de chances de s'user que les courroies en plastique...
  4. Ça fait des vaguelettes à la surface qui se voient, surtout quand le buse d'impression change de direction. Et le bruit est assez fort je trouve, en tout cas comparé au bruit normal de l'imprimante. Je vais regarder comment on fait pour démonter et vérifier les courroies. Vue comme ça, elles n'ont pas l'air usées, mais bon, je pense que les démonter permettra de mieux les voir ça.
  5. Je remarque que, aujourd'hui, ça le fait surtout lors de déplacement sur l'axe X, quasiment pas sur l'axe Y. L'usure des courroies pourrait générer le bruit et les vibrations? Ce serait les courroies moteur ou des axes? Ou les deux?
  6. Bonjour à tous, J'ai un problème depuis peu: mon imprimante (UM3E achetée il y a environ 2 ans) fait du bruit pendant les impressions, et ça semble générer des vibrations qui causent un effet de ringing sur mes impressions. Voici une vidéo où on peut clairement entendre le bruit, une sorte de staccato sonore à certains moments: J'ai fait l'entretien de la machine en me disant que c'était peut-être lié à ça: vérification des axes, huilages de tout le fourbi, resserrage des vis sur les axes, etc. Ça a un peu amélioré les choses, mais pas compl
  7. Sketchup est un grand spécialiste de la génération de fichiers stl pourris. Perso, je fais mes modèles sous Blender. Il faut télécharger un petit add-on officiel qui vérifie que le modèle est correct pour l'impression 3D avant de l'exporter en stl. C'est pas parfait, mais ça fait le boulot, et j'ai jamais eu de problèmes.
  8. Hello, I got my UM3E about two years ago now, and I noticed recently that it would make noise, like a sort of grinding, when printing, but only on certain position. It does not seem to be related to a specific axis, but more to printing on a certain position on the bed plate, or maybe when it is printing long lines. The noise has gotten louder and is now creating vibrations that affect the surface quality of the prints. I just serviced it: checked the axles, greased them, tightened the pulleys, pushed the motors down, etc, but it's still there and I'm at a loss as to wh
  9. Ultimaker 42, the answer to everything! 😋
  10. Hello, I'm currently printing a big order for a customer, with lots of small parts, and, when I did the upgrade to 4.2.1, I realized a problem with the support for one small piece. I fiddled with the settings for a while before going back to 4.1; I always keep two versions of Cura on my computer just in case, some of the last releases had very annoying bugs... I found out that it wasn't anything I did, my settings were right, but 4.2.1 does not generate support the same way 4.1.0 does, see the pictures below: - Support in 4.1.0: - Support i
  11. Alternatively you could get a UM3E with the bondtech feeder upgrades for abrasive filaments if you really need it. The 3E is cheaper than the S5, has a nice build volume (30*20*20), is dual print and can accept the CC core for abrasive if need be. It doesn't have the filament sensor, but I don't feel that this is such a deal breaker. Got mine for two years now, never been disappointed, every problem I encountered were due to user error, except a bent glass plate that was quickly replaced by my reseller free of charge, and solved thanks to the great poeple of this forum.
  12. Unfortunately I don't have the picture of the end result anymore, sorry. Though, I can tell you, as was pointed out, that the silicon will show the layers and every surface imperfection. There was a clear 'stairs' effect on the picture of the silicon part that my client made. But that was ok for him since it was some kind of proof of concept. You'll want to use a very fine resolution for parts that will be used. I would advise against trying to smooth the surface of a PVA mould with water, as it risk softening the whole mould.
  13. You're welcome, looking forward to see the results of your experiments in printing moulds!
  14. Wow, that's some very poor customer service from the reseller, and also a quite badly assembled printer. I find it quite improbable that UM would let such a printer get shipped out to customer and I wonder if the reseller did not sell you a printer that was returned to them, or one that they actually screwed up with (pun intended 😉 ) and decided to still make some money out of it. Maybe @SandervG could help? The forum is a very nice place, full of helpful people, be they from UM like SandervG or just regular users like me, but it can happen that messages go under the r
  15. One of my customer did it: he asked me to print the mould in PVA then he poured silicon in it. It worked like a charm. It was a small thing, a few centimetres of diameter. You can see the two parts of the mould in the picture below. I sent it with a silica gel packet to try and prevent damage by humidity during transport, some postal services can be rough and uncaring with packages, I had packages arrive with water damage due to rain or such.
