We now have everything ready to work out the distances This really depends on your personal setting of the condenser lens, LCD, mirrors, lenses... etc..
- The best thing to do is play with the distances and mark everything once you're happy with the result.
- Try the distances where you will think the projector is going to be. Some lenses wont focus from too far and too close.
This is my setting. I used two mirrors to keep the enclosure as small as possible.
