Somewhere I must have changed something on my printer (Replicator Clone) causing a odd pattern of spiraling/diagonal lines on perimeter walls in all of my last prints. It has happened last 3 prints and I can not find the cause of it. Possibly a setting in Slic3r. Can anyone ID this problem? I am new, but I couldn't find similar problems searching and I cant figure out what it may be yet.

Any suggestions are appreciated.
