Remove the front part of the [32] Mirror Mount attached to [15] Aluminum Frame For #1 Mirror.
Remove the mirror fixing ring located inside the [57] Lens Mount that was detached from the [32] Mirror Mount.
* Use a flat-head screwdriver or the like if needed if you cannot remove by hand.
Referring to the photo, attach the [42] Reflecting Mirror.
* The reverse side of the mirror is seen in the photo.
Attach the mirror fixing ring. Please install so that the [42] Reflecting Mirror does not rattle. Note the correct direction. The side that reflects like a mirror is the laser radiation side.
Confirm that the [42] Reflecting Mirror is attached like in the photo. Wipe off any dirt or fingerprints made at the time of installation.
There a total of four screws in two locations on the mirror mount. Fine tune the inclination of the mirror. The screw indicated in blue functions to contract the space between the two plates while the screw indicated in red serves to spread them apart. They can be used in two ways; “Loosen the blue and extrude with red,” or “Loosen the red and contract with blue.” Use the methods accordingly depending on the tilt of the laser beam. *A more detailed example of the adjustment screw usage will be given at the end of this stage.
After masking mirror 1, ensure the safety of you and your surroundings and briefly irradiate the laser. As it deviates to the right in the picture, move the mirror mount itself to the right of the picture by the amount that it deviates from the center (move mirror mount and aluminum frame by slightly loosening the screws).
iIrradiate the laser after masking the inner cover laser beam hole.
Adjust the incline of the mirror mount if it deviates horizontally from the center. A slight inclination translates to a significant movement. Exercise caution as a large sudden adjustment can be dangerous.
Move the XY Axis manually so that it is a close as it will get to mirror mounts 1 and 2. *Do not radiate the laser while moving the axes manually.
If mirror 2 is too far, it is possibly that it may deviate greatly from the center, so first test it from a close distance.
*If it deviates greatly at this step, readjust it before moving on.
Next, radiate again in the center of the processing area in the Y-axis direction.
*If it deviates greatly at this step, readjust it before moving on.
Finally, irradiate the edge of the processing area in the Y-axis direction. You can see that mirror 1 is tilting to the right in the picture above. Correct the inclination using the mirror mount screws.
The optical axis is aligned in the center as that basis.
Loosen the screw circled in blue and extrude the one circled in red.
Tilt to the left side in the direction of the horizontal axis. If it gets caught, tilt it to the right.
If it can be tilted vertically, move the screws again. It will tilt upward if the screw indicated in red is extruded.
If the screw circled in red gets caught, tilt it to downward.
Adjust so that even if the laser is irradiated at multiple points along the Y-axis horizontal deviation is kept to a minimum. (Likewise, it the deviation is vertical, adjust the mirror mount adjustment screws.) In the picture, since the optical axis moves to the left as it gets further away from “A,” the optical axis “C” is adjusted in the direction of “A.”
In this case, adjust mirror 1 by moving it horizontally, little by little, along with the aluminum frame. Move the aluminum frame in parallel. *Caution: if the aluminum frame for mirror 1 tilts, it will result in a great deviation in the optical axis.
Radiate the laser and ensure that the beam hits the center of the mirror from the front and back of the Y-axis.
