Hi,
I'm using the 1.2.9 for months, but from a week or so it's taking way to much , after 3-4 hours to slice let's say 10x10x2 cm and was unable to finish and save.
On quad core with 16gb ram, windows 7 it's using only one core and max 1Gb ram,even so i'm not able to slice allmost anything, and the finish is a crash.
Maybe some updates from windows or so are the root, but i was unable to find.
I have created from scratch.. no effect.
i like slic3r but i think this is the worst version from 2-3 years of use.
