1. Go to Print Settings, Click More, find Extrusion Width under Other Options section, select the desired value available in the dropdown menu.
For instance: The model’s wall thickness is 1mm, choosing 0.5mm extruder width would be the most ideal value to fill the wall.
2. There will be a default Extrusion Width value for each different Layer Thickness. However, you can adjust the Extrusion Width manually in the range of -0.15mm to +0.25mm, and the value cannot be 0.7 times smaller than the default settings.
