    That looks like the back end of the "Orville" which does not have a straight line on it. It seems that you may have your support on the piece a bit strong. What support settings are you using?

     

    Edit: Also, what slicer?

    yes orville stl

    in 45%

     

    you see the fails, i had now 3, and no idea how i shall improve it....

     

    first support was LINES but that was to instable so i go to zickzack

    Try this setup:

    1. To test your breakaway supports (assuming you are using one extruder), sink below the buildplate to minimize time and materials.

    2. I will sometimes cheat a bit on the quality settings for support by lowering the support line width. This can make the supports more flimsy though, so,,,,,up to you.

    3. Play with the Support Z distance to find a balance between supporting and just not enough contact.

    Cura 2.x has the same properties I am showing. No need to cut the model, just move it below the plate. You will probably have to turn off the "Automatically drop models to buildplate." so it is easy to do so. But, everything else is available that I used or mentioned.

    Yes Thank you, its a lot better then my 2 prints,

    but is there still a option to get it better or is that the point, where no improvement is possible?

    Those are the things I know to do. I actually use PVA for my supports. But perhaps you can look at a thing or two such as maybe less dense supports or even maybe playing a bit with the angle so that you have less support.

    You dialed the separation down to less-than-one-layer (It'll round up)?

     

    You could play with the interfaces (support floor/ceiling), that should help.

     

    If you're desperate, perhaps lower temps would help, but you shouldn't have to do that.
