[Problem surface]

Hi @Kaetzy,

Thank you for your post and welcome to the forums!

The references you see on the surface of your print are residue of the support which you have removed. Because the support is made of the same material as the print, there is good layer bonding / adhesion between the support and the print. That means, if your support is too close to your print it actually becomes part of your print. You can look for the sweet spot where it is strong enough to support your print, but the layer between your print and support is big enough for it to snap off easily.

We put quite some time in optimizing the print profiles and support settings. Are you using the latest version of Cura?

You could also sand down your print to make it super smooth, although post-processing is not an option for everyone.

I use Cura 2.7. That there is a connection between support structure and object is clear but not so bad. The object has no smooth surface, The surface consists of individual bands / Lienen

After removing the support structure, the surface looks like this. Why is that ?
