Slic3r Outputs First Layer Only
I'm hoping someone here can help me out with this issue I'm having... Repetier hasn't ever given me any issues before (it's worked flawlessly) until this morning, when I tried slicing a new print. The slicing took almost 10 minutes (which was absurdly long compared to how quick it has worked in the past), and when it finally finished it resulted in a 1-layer print. Does anyone know what causes this and/or how I can fix it? I've tried messing around with Slic3r settings but I haven't fixed it. Thanks!
Here is a picture of the .stl's:
