Using Cura v5.2.1, and I have "Layer Height" set to 0.2mm and "Bottom Thickness" set to 1.0mm. Cura correctly calculates that I should have 5 "Bottom Layers". However, when I slice it, only 3 bottom layers are laid down before my infill starts. This doesn't happen with the top, where there are correctly 5 Top Layers put down. The "Bottom Layers" says it can be affected by the following settings and i've included what I have them set to... not seeing why my solid bottom layers (lines) is stopping after the 3rd layer...help!? 🙂
Bottom Thickness = 1.0mm
Spiralize Outer Coutour = off
Infill Density = 20%
Layer Height = 0.2mm
