1. Confirm the symptom
Look at the first failed area, the material, and the slicer profile before changing settings.
2. Fix the simple causes first
Check filament dryness, nozzle temperature, bed setup, belts, and the profile baseline.
3. Test one change at a time
Use a small calibration print so you can see which change actually improves the result.
