[support outer wall]

Found the answer after some searching. For people in the future: Set "Support wall line count" to 0 (may be hidden by default).

[Stringing issues, Combing does not seem to work]

Thanks for having a look @GregValiant. 

I found the following: loading your file with all your settings and pressing slice once gives the correct output.

Just to distinguish the exact settings, I changed back to my old profile and tried to enable the differences between our profiles one by one.

Retract before outer wall did not make a difference.

Neither did some 4 other settings that were different.

 

What did give the correct result only compared to my previous try are these two settings:
- setting combing to "all"
- reducing the line width from 0.4 mm to 0.35 mm. (without this it still gave the same issue).

 

I am confused as to why it works, but I'm happy that works. I feel this is some form of bug, but at least I can work with it for now. Thanks a lot!

Apparently this was fixed in Cura 4.13.1. EDIT: When I uninstalled and reinstalled the new version for some reason it worked fine (I kept the configuration files). However, when I changed my model just a bit (increasing hole sizes) it was directly back to its old behavior. I don't know what to do anymore. 

[Stringing issues, Combing does not seem to work]

I have some stringing issues which would be fixed by combing. However, Cura is not cooperating. I tried every combing setting (All, Off, Within Infill, Not in Skin), but it still shows a lot of non-combed travelling
When testing, make sure you scroll through the layers each time after changing combing, after changing it hides somehow. See a save from my settings here: https://drive.google.com/file/d/1XUm6CdBS5uX9qkXwScF4EJePi8_rXZYl/view?usp=sharing

Can anyone please help to reduce the mid-air travel on this? TPU strings horribly
