Frustrated with "subjective" flow rate calibration in OrcaSlicer? This quick guide will help you ditch the guesswork and objectively master your flow rate for consistently perfect prints.
Why Flow Rate Matters (The Short Version)
Flow rate (Extrusion Multiplier, EM) controls how much filament your nozzle extrudes. Get it right, and your prints are strong, dimensionally accurate, and smooth. Get it wrong, and you'll face issues like:
- Over-extrusion: Wasted material, blobs, stringing, rough surfaces, weakened parts.
- Under-extrusion: Gaps, weak layers, poor surface finish, holes.
