Hi Edel,

The attached photo, is it 3D Printed?

If not, could you add a picture of your 3D print? That always helps in diagnosing an issue.

Based on the picture, I don't know if I should look at the crack, or the surface structure or something else..

Looking forward hearing from you!

I think the object of interest is the string of filament while the blue paper tissue is just used as a photo background ;-)

Holy! Thanks @avogra that was hard to see. Ok @edel please explain where that filament came from. Was an atomic? It's that how the filament it's inside the bowden? It's the filament just after going trough the feeder ?

Info info and more photos. How it should be, how it did look, more.

Hah! You are right! In my haste I interpret that as a crack in the surface. Now I feel stupid
