Help. I changed something in print settings and now I'm stuck.

I don't know how I did this. Now, if I try to slice something hollow like a cup or a cylinder, when I slice it, Cura fills it in solid. How do I undo this? Is there a way to reset default settings?

You have discovered the realm of "No Holes".  It's a strange place where doors and windows and roofs are not allowed.  The only way you can escape is to go to the land of Mesh Tools and kill the "Remove all Holes" wizard.  It's possible that his apprentice the dastardly "Make Overhangs Printable" witch is involved.   You may have to kill her as well.

 

And now you know that 3D printing is not the safe hobby you had envisioned.
