Thanks Ian, that makes sense. It only does it when try to print a U shaped item. I'll try calibrate using those objects

This is plastic that oozed from the nozzle while it traveled to the part of the model in the picture. That ooze got wiped on the edge of the model, then the next layer's ooze got wiped on to the previous ooze, and so on giving the diagonal effect you see.

In the Dimension tab, try setting retraction distance to 1 and retraction speed to 45 and see if it goes away.

Here are a couple of things you can print to help tune those settings-

My guess just from seeing that is something wrong with the orbit command?

The only thing that I could possibly imagine that being, from the looks of it, is support material. I had a few prints (iphone case) that would deposit support material that looked eerily like that, at a diagonal as well, so that when it ran a bridge, it would be supported. No idea if that is in the .stl, skeinforge settings, or what, as I really don't have the experience with the software that some people on here do.

It's on a pretty big print, 120x70x30mm. Most of the print looks fine, but on this one corner, I have all this odd loops sticking out. What is causing this and how can I prevent this from happening?
