Turntable alignment seems random from project to project

[kless]

Hi I started on a new set of turntable photo scans of some rocks, the first rock aligned perfectly the top and bottom connected with no issues the second rock which has the exact same amount of pictures and coverage as the first rock just doesn't want to align.  I've tried adjusting settings but it makes almost no difference.

Hello kless,

Have you checked the amount and distribution of the tie points in both sets, do they look similar (well spread and more or less uniformly distributed)?

I feel real stupid I think I figured it out, I accidentally bumped the lens and changed the mm from 53 to 54 for the bottom photos.
