LASER ISTALLATIO
1.
Set the laser on the bottom enclosure with the cable end to the right (as you face the front
of the machine).
2.
Pull the red and black cables through the grommets on the lower enclosure. Route cables
to the large power supply and install ring connectors using crimpers. Screw the red cable
to the +28V side and the black cable to the -28V side.
3.
Install the output end plate/shutter block combination on the output end of the laser.
4.
Slide the laser up to the laser support brackets. As you look at the laser from the front of
the machine, lift the right side (power cable end) up with your right hand about half an inch
and install the far right screw into the laser and use Locktite 242. This screw goes through
the middle hole of the far right hand bracket. Tighten the screw so it is snug, but not tight.
Next, lift the left hand side of the laser, install the screw in the upper left corner and snug it
down. The screw in the lower left corner is next, followed by the screw in the middle of
the bracket that is second from the right. Finally, install the two screws in the top and
bottom of the laser bracket second from left. Tighten all screws down tight.
