Why not extruding enough plastic?

1. Incorrect filament diameter;

2. Increase the extrusion multiplier.

The solution to under-extrusion (not extruding enough plastic)

Why there are holes and gaps in the top layers?

1. Not enough top solid layers;

2. Infill percentage is too low;

3. Under extrusion.
