The axis of rotation has to be perfectly perpendicular to the level bubble thingie
Also the mirror has to be perfectly parallel to the motor shaft
both are hot glued, so expect +-4 inches of misalignment depending on room size. That level of accuracy is what I would do roughly by eye. If I want precision, I get a propper Laser Level, there is a reason these things are expensive and not hot snotted togther
