Question Cura Slicer Failing (Won't print internal geometry and fills in hole)

[Mike23Like23 0]

Can anyone help me out with my part? I have this vase I'm trying to print for a levitation platform i have but when i went to print it it infilled my internal geometry. I disabled union overlapping volumes but still no avail. It infilled the entire bottom instead of leaving the hole and space for my locking mechanism. I've tried different print orientation and still same issue. Is my part flawed? Thanks in advance.

Wait a minute...didn't I see that somewhere?  I see that anti-gravity is involved somehow but this is more like time travel.

Yea I posted this in a few places to get the fastest response lol. So you may have seen it.

I responded to one of them.  I think it was the old thread you brought back to life.

Cool.  Not just Time Travel and Anti-Gravity but Resurrection too!  👼
