[Problem with i don't know what]

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

[Problem with i don't know what]

will try those too

thank you very much

[Problem with i don't know what]

ok i got it , it was perfectly explained,

i will try it and get back to you

thank you very much

[Problem with i don't know what]

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?

[Problem with i don't know what]

if you see cearfully at the video at exactly 1:00 you can see a clear shoot that the tube is all the way in and you can hear the extruder working and the material flowing

here is a video . sorry for the shacking

after this video i tried to print something but after 00:13 min same thing hapened , stoped extruding here is a pic of how far the print stopped

any clues would be more than welcome i am starting to lose hope

thank you very much in advance guys

[Problem with i don't know what]

i didn't remove anything

it is there . Just at the time the picture was take i was feeding material manualy so i had to take it out . Just as we speak i am up loading a video on youtube so everybody can have a clear understanding of what is happening.

[Problem with i don't know what]

I do have the boden tube that guides the fillament to the head

in the first picture you can see it on the backround as i have removed it and inserted material by hand

after 2 days it still does the same thing

i removed everything cleaned everything with a hot air gun , did the atomic thing .

printed once worked fine and thats that .

[Problem with i don't know what]

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

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 .

But while printing it just stops extruding.

The material gets , lets say , "knoted" on top of the heater where the brown plastic connects with the white guide for the fillament tube.

I hope i gave a good description of what is happening

i have attached a few images to help visualise the problem

Thank you very much in advance
