For the brave (or unlucky) who attempt a CO2 laser alignment, here are three small pieces of plastic that saved my nerves and a lot of time.
I did follow indications here (it is in French) : https://fr.omtech.com/blogs/principes-fondamentaux-des-lasers/alignement-du-miroir-graveur-laser-comment-aligner-un-faisceau-laser-co2
Set the CO2 laser power to the minimum necessary to slightly burn the tape.
The first one T1 (hood hole target) create a kind of target to be placed on the hoods hole. This will ease the alignement when you are using to the mirror 1 and mirror 2 screws. The goal here is not to put the laser spot right in the middle, as the hole hood is not specifically aligned with the mirror center, but to give some visibility. I also give you multiple shots possibilities, by turning T1.
The second one T2 (mirror target) will enable you to visualize the laser spot on the mirror (1 & 2), this allowed me to center the laser spot on the mirror 2 without dirtying it, and to verify the spot from the CO2 tube on mirror 1.
In my case, I didn't had to modify the tube alignment.
Added a new helper T3 CO2 head target to help centering the beam on the final lens, last mirror alignment.
