A500 not detecting calibration marker, any advice appreciated

[Jobber]

Marker is not being detected during lens calibration of A500, any advice? Thank you. (P.S. Also, got it rotated properly. Still doesn’t work. )

As a start cover your honeycomb and adjust your light, maybe cover the light with some strips of painters tape.

I think I solved it. Need to use their circle card, can’t print custom. Appreciate your help!

You should lower the camera position as well. The camera only needs to cover the exact workspace, nothing more. This will increase usable resolution and increase quality.
