It's so kind of you,yossi.Maybe you can have a try.@Bernd

[Bernd]

I can try, because it must be that it does not work indeed anything. Where did you get the new Teflon from to replace it?, And how did you get the old out of there?

[Bernd]

I have looked at the nozzle in more detail, which should be 0.35 mm but it looks as if that is substantially smaller, it may be because the does not come out the filament?

The filament doesn't matter to the size of your nozzle,but the groove size below.BTW,what size is your filament?

[Bernd]

my size of Filament are 1,75 !

OK, I made for video, mine is not the same as in the video but it went. In Hotend everything was and by the rausmachen is also the Teflon broken. the next is the role the wobbles and if there is a ball bearing should be in there then I think that this is broken. Unfortunately, I can not take this one so apart like in the video. but since the error will be. Motor is OK, fan and heat sink also.

and this one here is plastic no aluminum metal as shown in the video! I just wanted to say again.
