I'm having trouble printing circular objects that vary in radius as they go up. Its only on the bottom layers going from a smaller radius to a larger one. It seems that the outer ring tends to curl up a bit. Attached a picture of the problem.
Printing on a prusa i3. Printing with PLA, have tried extruder temps of 190-210, bed temp of 60, layer heights of .1-.3, Have tried with supports but with no success.
Attached a photo of the problem. The print I'm trying to get to work is :
