Inconsistent extrusion

Printer: Vcore 3.1, Phaetus Rapido + LGX Lite combo Slicer: PrusaSlicer (with its standard 3.1 profiles) Problem description: Even after completing the commissioning guide from the official site with all necessary calibrations, I still get this kind of issues on my prints (basically everywhere from top/bottom, to outer perimeters and infill), looks like underextrusion(?) I'm just printing PLA for these first few tests, but even changing to other spools doesn't help, does anyone have any solutions in mind?

Solution:

Looks like it only needed to be cleaned! I disassembled the whole extruder and cleaned it thoroughly with IPA (especially the teeth that grind the filament, and the issue seems to be completely solved 🙂
