Filament Thread Pulling

[ViperZ 0]

Hi there.
I'm looking for the cause of the filament's threaded condition, which is very bad.
The left side of the picture was printed in Cura and the right side in Simplify3D.
The pull speed and distance are in the same condition.
What parameters in Cura do I have to adjust to make it so?
Best regards.

I think it's a bug because there is no retraction

When you have small parts, these "Travel" settings come into play.  They are described in their ToolTips.

Minimum Extrusion Distance

Retraction Minimum Travel

Max Comb Distance with No Retract

If your Max Comb Distance with No Retract is set higher than the width of that part, then there will be no retraction for the combing moves you have highlighted.
