Bottom part of spherical objects print problematic

# Bottom part of spherical objects print problematic

(Asked by: username_0 on 2022-03-05)

I got a Flyingbear Ghost 4 and using Cura. It is doing fine until I have to print spheric things. I'm using a high density material that needs to be at 210 °C and slower print speed. I also built a top and a door for my printer so it's partly enclosed at 90 %

An easy example of what I got is a sphere object.

The lower half is messy with uneven surface, lot of visible strings marks at firsts layers. While upper part is just perfect. I tried to to work around it multiple times but can't find any worthy info on internet. Tried to slowing down the printing speed by max 50 %, thicker shell, nothing seems to work.

Here a Lapras I did to my son to show you.

Can you help me with this?
