  1. Hello, You can print a new one! The file is on GitHub https://github.com/Ultimaker/Ultimaker3 file is: 2129-F STEP to transform into STL or you can download from below! Original Tab is Polycarbonate (PC). Print it in CPE or in CPE+ and it won't stress crack anymore and it will be almost transparent. PC stress-cracks under stress when in contact with oil... Enjoy! 2129-F (repaired).stl
  2. Hello all, XT have given very good result fo me so far on most of the prints. Only on a very challenging print when the nozzle has to go from different place very often without printing much in between the retractions make the filament to worn out and flatten down. At one point the filament cannot be driven forward anymore. Actually I tend to increase retraction length to reduce stringing, which may cause the issue. The best thing to do then is to change the material, unload it, cut the 0.7 m which is corrupted (with indentation marks) and then re-introduce it to start with a "fresh" filame
  3. Bonjour Rigs, Je vois que tu as 2 réglages différents pour le XT. Moi je penche pour 235-240 Deg C, flow: entre 110 et 125% retraction length: 6 à 7 mm retraction speed: 45 mm/s J'ai aussi besoin du fan surtout pour éviter que la point du tetra_wire (par exemple) ne fonde. j'ai des infos sur le XT n'hésite pas.. Cordialement Ludovic
  4. Bonjour, UPET, n'est pas un PET classique qui poserait énormément de problèmes du fait de sa vitesse de crystallisation. Il s'agit d'un Copolyester Amorphe. Vous pouvez vous en procurer sur http://colorfabb.com/xt-copolyester. N'hésitez pas à me poser des questions sur le XT et partagez votre expérience sur ce filament avec moi. Salutations. Ludovic
