How to force Cura to walk through a layer in one run? I already tried a lot settings in Cura and try to search for a solution but without success. Maybe someone got this issue and solved it.
I want to prevent Cura from printing such gaps at the wings to make it in one run. With ironing one run would (hopefully) bring better results. See the animation for what I mean.

Why want to do this? I hope to prevent thes ironing issues shown in the following pic.
I am not aware of a general solution.
For your specific issue, try rotating the object 90 degrees around the z-axis.
