[Very little extrusion of the first layer]

You have looked at your Initial Layer Flow %?  The flow of layer 0 is just about exactly 5.00% of the flow shown in Layer 1.

Thank you so much, that solved the issue! 

[Very little extrusion of the first layer]

I am using Cura to slice a simple cube. The extrusion amount of the first layer is extremely low, but the other layers are fine. I copied the first 2 layer g-code here, and I would like to know if anyone have an idea to solve this issue. Many thanks!
