Cura v3.3.1 Concentric Print

[mnis 11]

Cura v3.3.1 Concentric Print:

Machine = Ultimaker 2 / Layer Height = 0.20mm

I miss the first line / first lines starting in the center of a diagonal printed object.

I first thought it might only affect the first one or two layers, but each concentric layer starts with a slot in the center.

I always get a letter slot ... LoL ...

Is it a calculation error in Cura, or does anyone know a solution to this problem?

 

Other abnormalities:
- It is driven in adjacent holes
- All around the object to be printed are a few erring runners on a 2mm wide brim. Fortunately, these aberrations are not continued in subsequent layers.

- It is driven over printed surfaces, although this was prevented in the settings. Anyway, I think I made the right settings.

 

Edit: I had mistakenly and temporarily set the combing mode not to "all". The aberrators are gone and it is less driven through holes. But the other mistakes are still there. In addition, the Z-jump setting during the material retraction is ignored.

 

I think I have not seen this conspicuousness in older versions of Cura.
