Perimeter and Infill Problems

[danluc 0]

Hello all.

I finally managed to get proper circles by tightening the belts but one problem still remains. The infill often doesn't touch the perimeters.. The first few layers are usually alright then it all goes south. Parts are usable for the most part.

I have no idea why the infill wont touch the perimeter and why sometimes the perimeters are spaced apart. I even slowed it down and nothing. I use Replicator G with slic3r I think. The standard software Ultimaker came with. And the rofile is Normal Print.

This is the last problem to overcome before great prints.
