Do you have to align camera for each new project? - Creality Falcon2 Pro

Hello! I am new to using this machine and am having some trouble with the camera alignment process. I have watched a few videos and feel a bit more confident in doing it now, but I read on the back of the alignment card that you need to re-calibrate for every new thickness and material. Is this the case? How often are you all calibrating/ aligning your camera?

Machine: Creality Falcon2 Pro 22W
Software: Lightburn

I am having the same issues with the Falcon2 Pro 22w. It seems when I run test runs and move a test piece around, the errors seem to be directly related to the positioning in reference to the camera. I noticed the errors became predictable and the error runs seemed to be where shadows would be if the camera (center) was a light source, if that makes sense.
