I had to break the seal on the lens to be able to focus it, so it was done outside of the mount. I placed letter patterns on the bed (not shown) to get the focus dialed in before calibrating again, holding the camera at approximately the height it would be mounted. The letters made it easier to determine when the lens was getting a clearer picture. For the camera calibration, I followed the angles in the prompt pics. These images were just to show the pattern not being recognized and then getting detected after adding a contrasting background to the bed (I realize they are not good example pics). I was able to successfully run calibration again afterwards. Just be sure to remove the bag before running alignment…
