Merci de ta réponse. Comment reconnaître si le PTFE est mort ? il ne parait pas déformé ! J'ai lu sur les forums qu'un PTFE avait une durée de vie de plusieurs centaine d'heures. Or mon UM2 a moins de 100 heures de travail (j'estime à 80 heures). Faut-il conclure que si la matière ne sort pas de la buse, on fait un "nettoyage atomic", et si le problème persiste, on change le PTFE ? cela me parait difficile de démonter la tête toutes les 80 heures ! C'est le support de Makershop qui m'a dit qu'il fallait changer le PTFE.

Hi, I have problems with the feeder: after a while, no material comes out of the nozzle. The filament is no more driven by the feeder. As suggested, I made atomic method, I cut the damaged filament each time I get this problem. The vendor's support department told me the problem comes from the PTFE coupler. I would like to know if such a PTFE coupler needs to be changed; it does not appear distorted: My UM2 is new, and has worked during only 80 hours. Moreover, this problem appeared after a few hours of work, when the PTFE was quite new. Thanks for answer.

the first prints I did (with PLA) are very smooth when I touch the surface. After few days (the first filament coil not half consumed) I begin to get under extrusion problems: nothing printed, or only a part of the printing. I made several "atomic method" in order to clean the nozzle, also, I tightened the filament feeder, and now, the filament coming out of the nozzle seems to be very thick: when the print is finished, the surface is not smooth: with my nail, I can move some filaments on the surface of the print, Please see this video: http://www.softysoft.fr/_3dprint_problem.mp4 Thanks for help.
