After days of trying and getting really frustrated, maybe this forum can help. I have not used the box yet. So the setup is just on the table.
The table is as level as I can make it. I have printed the protractor templates (from document I found ___ forgot exactly, but the title is "Setting up for the Laser Shoot.docx"
I also use graph strips.
I angle the first mirror 45o using the protractor template above (location: on the middle line, about 2 inches in front of the laser)
Then using the graph strips to find where the laser reflection should be and then place a second mirror there.
As simple as that. BUT for the life of me, for days I can not even get the laser beam to correctly fall in the middle of the second mirror.
It is always off by 3-4 millimeter and that is enough to create big enough error that I can not even hit the third mirror.
Anything I do wrong? How to accurately angle the mirror(s) and then getting a correct angle to position the "catching" mirror.
A picture might help...
For the 45 degrees part you might want to use a 45-45-90 triangle to be more accurate.
