Why are my corners raising up? (on top of print, not lifting off bed)
This seems to be a new issue since I have adopted slic3r 1.2.9. My corners are raising up significantly, and it gets progressively worse with round slopes (e.g. when printing a sphere). It looks like it is extruding too much in the corners, or not retracting enough maybe? I have attached some examples of a perimeter width test (the parts don't quite fit, but I think if I can solve the corner round/overextrusion they may be close).
Edit: I am printing natural PLA at 200* with 60* bed temps and 15% infill with a part cooling fan running at 100% for the duration of the print.
