I am printing ABS at fairly slow speed and at just a tad above the lowest at which I can extrude which is about 210c (225c for first layer and then dropping from there layer by layer) and the heated bed at 110c for the first several layers and then dropping to 90c for the duration. I also have an uber-cool [http://www.thingiverse.com/thing:537918
] ducted fan mounted for active cooling:
All that said, and to leave no stone unturned, I did print the three objects in the below picture in the same session. The problem with the Pyramid is still evident. The Surface calibration object is pretty good and the Marvin would be great except for the issue with the ring at the top and the extra brow above the left eye.
I am going to try and get ReplicatorG or Slic3r to work but in the meantime any other advice would be appreciated. It still seems to me like an ooze problem but I have tweaked parameters left right and center without fixing the issue!
