There is that step in the instructions where it says to push the tubing so it sticks out 8mm. Then after you pull it back, it says again emphatically that it must stick out 8mm. But pulling it back in the plastic compression fitting slides it back 2mm. So I pushed it out another 2mm, so it stick out 8mm -after- taking into account the pullback in the compression fitting.
Was that wrong? Have I compressed the end of the tubing so it constricts too much?

Sigh... looking over it again, I see it does -not- say 8mm after pulling it back. I also see I mistakenly put the end -with- the blue tape in that end.
Now if only I can get it apart to start over.

Hi Polymorph,
I posted a picture of the filamanet extracted from the machine on the first page of this topic.
You can see a restriction in the diameter of the filament just above the section that expanded in diameter. When this happens, it's very hard to remove the filament as the expanded section does not pass through the section of the tube strangled by the clamp.
I managed to get out of this blockage by pushing hard on the filament during several minutes to soften the plug and pull it very quickly to pass the clamp before in hardens again...
