Preview is not whats printed

Hey printer commanders,

I just got my printer working for the first time and printed one fully working model, now i´ve stumbled about a peculiar problem.

Every model I´ve sliced with Slicer and printed with either pronterface or skeinforge is shown correctly in the Gcode viewer and behaves normal. However what comes out is some weird streched and screwed up version of it.



This is supposed to be the base for a simple cube but the not even quadratic and whats with the round edges?




The same happens when I print Mr.Jaws there the 1 layer isn´t even solid and the the shell does only partially look like the it should.

Any ideas?
