No I didn't used any plugin.
My Cura Settings:
Layer Height: 0,2mm
Shell Thickness: 0,6mm
Print Speed: 80mm
Fill Density: %45
Bottom & Top Thickness: 2mm
Yes in expert setting solid infill and bottom fill is ok. Also It makes initial layers fully closed. But up layers like that.
We bought our machine 1 week ago and using. So machine is new, I don't think about mechanical problem :/

Same problem. :unsure:
