Using the laser alignment target. Sometimes casting a shadow over the target area helps visibility on dark surfaces.
That is, the dot will be bright when hitting the white "+", but may "disappear" when it hits the blue area of the target card. Just use your hand to cast a shadow and the dot should become visible.
This photo of the laser dot was taken during a vise alignment with the tool about 1.5" above the jaws.
As you can see the dot is extremely small and is being viewed under strong ambient lighting. The jaws are highly reflective, so in this case, strong light actually makes it easier to resolve a small dot.
With a bit of patience you should be able to tune out any perceptible wobble in the laser dot. You can check the fine alignment by spinning the quill by hand and looking for any "wobble."
The LC/EF does NOT need to rotate during normal operation.
