Slicing taking ages to complete

Hey guys,

I'm trying to slice this STL: ; and it´s taking forever... Without supports it takes around 45 minutes. With supports I still don´t know, since i left it overnight and it´s not yet completed.
The same object sliced in other apps give me almost zero-waiting time.

Anyone has any clue of what could be?

PS: It´s not the object fault. Every "big" STL (more than 5MB) takes ages to Slic3r.
PS2: It´s not a hardware problem... Note is a i5-7300HQ, 16GB RAM, SSD and 1050 videocard...


  • It is the option "Avoid crossing perimeter" I think. This creates less crossings for nicer surface but detecting these crossings seems very time intensive.
