How Do I Calibrate Z Offset?
Calibrate Z offset by lowering the nozzle until first-layer lines bond together without scraping, ridges, gaps, or a rough over-squished texture.
Fast answer
Calibrate Z offset by lowering the nozzle until first-layer lines bond together without scraping, ridges, gaps, or a rough over-squished texture.
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.
