I can't calibrate camera lens

Hello, problem is:
First my camera (120 degree 5mpx) working fine, i calibrate lens and alignment and matching was great. (laser cutting line was exactly where it should be)
I made couple adjustments around my laser ( i make wooden frame and my own fan system keeping air fresh in my little shed).
However i need to change my camera positions and when I trying calibrate lens its look like it was done. I tryied so many times and still i have got this:

Unless you’ve changed the lens on your camera you shouldn’t have to run lens calibration again. Just run camera alignment.
