Hi Guys,
To get the red pointer aligned to the laser beam path is very simple.
Set up you laser how it will finally be on your table exactly parallel with the axis you have chosen then place a piece of wood about 2 meters away and in line with the laser path.
Fire a very low powered shot of the laser at the wood so it leaves a small round black/brown spot on the wood and don't move anything afterwards.
Then align the red pointer to the exact center of the spot.
Do this at about 500mm away as well to get the alignment exact.
If you set up the combiner mirror so that the laser beam passes right through the middle of it then the red pointer is aligned to the center of that, then it should go very well.
Then you know the red pointer will be spot on and you can then set up the rest of your mirrors knowing that it will be right on the mark when you turn it on and can burn the crap out of everything.
Easier done than said.
Rich.
