[How do I fill gaps]

Thank you,

I did have the ignore small Z gaps checked, but unchecking didn't make a difference and fill gaps between walls is set to everywhere.

I don't want to slice the model thinner as it already takes 19:13 hours to print. Any other hints?

[How do I fill gaps]

I have a model which is a cup holder (a hollow cylinder) with the FCB crest on it. To reduce support, I've tilted it in 45 degrees. But I can see there are gaps in the print (using 'fine' print and 0.8mm walls with wall line count of 2). How can I make cura fill them?

[Different layer thickness for different layers]

I'm printing a cup with a logo. I want to print the logo in 'fine' mode (0.1mm), but the rest of the cup can be 'normal' since I'll probably sand it anyway. Is there a way to set only some layers to be fine and others to be normal
