i got a new laser, LC1290 from gweike with 100w RECI, and i had to dismantle the top parts, not the rails, to be able to get the monster in the office.
now i have a biiiig problem aligning the mirrors. after many hours of forum reading, i think 3 mirrors are not on the same level.
so, i'm coming with some questions and begging for some experts help and reply's
1. is a must to center the beam on all 3 mirrors?
2. how can i check if all mirrors are on the same level?
3. is anyone have a tutorial to allign the mirrors from point of mounting, not just fine details?
4. at a surface of 1200x900, the dot can be set to hit the same place, on all the table surface, or it's just a myth? i can do that for the left half of table, but not for the right
thanks for reading and for possible answers
