Hello everyone,
I’m experiencing an issue with calibrating my lens using the 9-point adjustment in LightBurn. Despite multiple attempts, I can’t get a perfect alignment.
Observed issue:
- A 50x50 mm square is accurate.
- A 50x50 mm circle appears correct at the center, but at the outer edges (in the corners), it stretches to 50.5 mm.
- The smaller the shapes, the more the discrepancy increases: for example, a 30 mm square becomes 31 mm.
- I also have the same issue with my 250 lens, although the effect is slightly less pronounced.
My questions:
- Is there a calibration method with more than 9 points for a more precise adjustment?
- Do you have any advice or specific settings to adjust to eliminate this distortion?
I am attaching images along with my current settings. Thank you in advance for your help!
Best regards,
Teddy
