Thanks a lot, guys! Your answers are really helpful.

About the simulation you did:

@Steve_in_Denver

When I simulated the calibration process (for my lens type, working distance, etc.) I found that I needed a minimum of 15 degrees of rotation in the calibration target to get good results.

Is there any procedure where I could get the requirements of my own setup? did you use a specific software or procedure?
