one of the old members (marm maybe?) did a lot of abs printing and 85c was what he always recommended.
I think the basic idea is that you need to be just over the glass point of the material to avoid the bottom couple of layers cooling sufficiently to shrink, but not hot enough to make it so soft that you will get material slumpage. Which will have aripple effect throughout the entire print.

It's why I generally print pla on a 65c bed.
Just seems to stick better.

But basically 85c seems to be the best for abs.
So any machine with a 100c print bed will - technically - print abs.
But it is NOT a good 3d printer filament.

pla, pet-g and all the newer materials are ALL better.

Oh yeah here's the skinny on the mini:
