Difference between 3D model and G code

xnordz

Hi,

i' ve just completed the builing of my K8200 and it really works great !
i've read a lot about the Z axes wobling, so i wanted to improve some pieces.

i wanted to print the piece described in the picture, but slicer do not seems to do the work well.
as you can see, there's a difference between the object and the G code. there is a space at the bottom of the model ! and i dont know why !

hope you can help me

I guess the model is not manifold. That can produce the most strange results when slicing. Try curaengine instead. It has an other algortihm that often works. Or try repairing the stl first.
