I'm using 15.04.03 on a Mac and a PrintrBot Play and I have noticed that the last several layers for a model print really slow making the time estimate wrong. I 'm not sure if I have a setting set somewhere that is causing it. Nothing seems to come to mind. For example I printed the all-in-one print elephant, LFS_elephant .stl, and the last several layers of the ears took over 20 minutes. The issue doesn't seem to happen when printing a test 3mm box, only on a curved surface.
I tried searching the forum, but could not seem to find anything to match what I'm seeing.
Can anyone guide me to a solution?
Thanks
Dave
