Now that you can remove the screws, you might want to replace all of them with socket head cap screws and forget the glue. Those Phillips head screws are not suited to precision alignment mounts because they require sometimes considerable force to keep the driver in the slots as you are fine adjusting the flex mount's position. Is this the kind of hardware detail that is typical of lasever?
I know what it is like to enter a hobby/profession at the mid level ie to miss the ground up education, yet be unwilling to just go out and buy the result and treat it as a black box (in this hobby that is literal). So, once you get this projector sorted out, you might want to undertake to build a small, low power satellite to gain a little confidence and better prepare you to trouble shoot the more complex systems. And of course, you'll end up with another projector.Nope i was experimenting with what to screw to make it go the direction i want.
