loops and perimeters inside out?

[alaris2 1]

I was having what I thought was a hardware problem, but now I think it's a misunderstanding of how the slicing works.

I tried to print a box with some holes pre-drilled in it, but got rough patches on the outside of the box (example image here -

)

looking at the gcode, I see the outside of the box is red, except where these weird marks are.. where it's green.

I think green is loop rather than perimeter? but why are the loops and perimeter getting turned inside out like this and how do I fix it?

I've seen it happen before, and I'm still not sure if it's my mistake in the preview, or that Skeinforge does something strange. However, the path is still correct in this case, only the type seems wrong.

did you see the first picture of how it prints tho? where the green is on the outside the print becomes very rough - this was the reason behind my question the other day about loops -> perimeter -> infill vs perimeter -> loops -> infill.

I'm not sure the preview is wrong, I think something to do with the slicing is wrong (perhaps because it's confused by some aspect of the model?)

I mist the photo, sorry.

I've seen roughness like that before, for me it was the extruder that was slipping at higher speeds.
