What Causes Layer Separation?
Layer separation usually means poor layer adhesion caused by low temperature, too much cooling, wet filament, drafts, or printing too fast.
Fast answer
Layer separation usually means poor layer adhesion caused by low temperature, too much cooling, wet filament, drafts, or printing too fast.
Look at the first failed area, the material, and the slicer profile before changing settings.
Check filament dryness, nozzle temperature, bed setup, belts, and the profile baseline.
Use a small calibration print so you can see which change actually improves the result.
