Hi
I have Adjustet the mirrors on my 80w red and black chinese laser, the dot is roughly in the center of the third mirror. But when trying to asjust the lens vertically, I can see that the mark left when moving the table 100mm down is far from a circle. It almost looks as if something is shadowing for the beam. I have alteady removed the air assist nozzle...
Any input or help apreciated
