Hello, I have recently had some difficulty getting the outlines of my prints to merge together. The nozzle diameter is .6mm and im printing polycarbonate at 270c with a bed temp of 110c. I have adjusted the extrusion multiplier, extrusion width and overlap settings many different ways still there is always a gap between the outline layers. This is an issue because I need a strong wall for my screw holes. Any tips on fixing this issue?
