  1. Goodmorning i think it's ok now i did cut a few mm from the bowden tube and now its running perfect thank you very much guys
  2. ok i got it , it was perfectly explained, i will try it and get back to you thank you very much
  3. the problem is , in my understanding , that the tube always comes out just a few mm , but still in side the white hot end isolator coupler , and the result is hot semi melted fillament pops out and gets knoted as the picture with the purple fillament in the first post . the question is why is the tube moving out of the isolator coupler ( i have the blue safety clip on top always in place ) and how can i prevent it from happening?

  8. Yes i got the PEEK part screwed to the hot end isolator below the white coupler . and the "guide" transparent tube goes all the way in the white coupler here is a photo from the side
  9. Hello there My first time writing here I have an ultimaker original plus for a bit over a year now . never had the chance to properly use it because of lack of time . here is my problem recently i replaced the hot end (all of it , nose alum. block , heater , thermistor everything) when i am trying to print , the printer stops extruding after a few layer ( 5-10-15 depends on the scale of the object) When i push the material by hand it flows like a charm , when i use the extruder same thing , works perfect .
