When using 3mm filament, it is best to tell Simplify3d this little fact, otherwise it thinks you are using 1.75mm filament. Now, with that I have finally found out where the setting is (quick start didn't address it) that little problem has gone away. I'll spend more time playing with it.
At least you figured it out! We've had the opposite problem with Slic3r a few times - people posting "what's wrong with my print" pictures only to figure out they had forgot to set Slic3r to 1.75mm instead of 3mm.
