Cant print spheres correctly.

[jeeplvr]

I searched and found nothing. Why are my spheres turning out like this? The lower half is cone shaped and the upper half is perfect. I have tried every conceivable support combo and no support.

I'm trying a prime pillar next to see if the lower half of the sphere needs more cooling time. It prints the same with or without support. I tried dropping the bed temperature to minimize radiant heat but nothing changed.

Can you post a factory file for this model & settings, please. That way the learned folk on here can see what changes may be worth suggesting.....

Heres the factory file

There's two changes I would try....

Increase the perimeters = to say 4 or 5
Reduce perimeter speed - say to 75%

The reasoning behind this is that where you have an overhang, you need more perimeters to ensure the overhang has sufficient support, and printing slower will give a much smoother finish on the outer edges.
