I used ABS at 230C and 30mm/s. The bed was set at 110C. I had two fans on it, one in front and one in back the whole time.
I'll try one later today or tomorrow with the new code you sent. I have a 12-hour print to start right now. I did do a new test last night after my first one. I created some small supports to stabilize the sphere but the ones I created were still too small and they eventually broke loose. But I did get about 75% of the sphere. The first few layers did curl and get a bit fatter than the others like you speculated. It was interesting to see how faithfully the printer captured the facets of the sphere. The sphere didn't have enough geometry to make it smooth. I want to try to print a golf ball with dimples. That would be a good test.
Here are the photos from my second test last night. I had a jam last night and was able to mostly clear it without having to pull my head but I don't think it was totally clear when the print started. You can see the first few rings of the bottom of the sphere are messy. I think those would have been nicer if I hadn't had the jam. But, still, I got very good results.
