The camera preview is blurry or hazy with localized light spots, so auto-recognition cannot lock onto the contour. Reflective materials are extremely sensitive to lens contamination.
Troubleshooting Steps
- Blow off loose dust on the field lens below the galvo head and on the coaxial camera lens with an air blower first.
- Wipe both lenses in one direction with a lint-free cloth — never scrub in circles.
- Do not use paper towels, tissue or clothing; they scratch the lens coating.
- Check the preview again: if the haze is gone but recognition still fails, verify that the material is at the correct focal position.
