6. Optical Path Adjustment After let all power cables connect well and electrify, turn on the engraving machine power supply, at this time, the machine starts to reset and return to the last origin point . All above shows that the machine is running normally, then turn on the laser power supply, begin to adjust the optical path. As shown in Fig.F1-14: F2-14 Firstly, adjusting the laser position. Make the multilayer adjusting paper stuck on the 1# mirror frame, and then push the Pulse key on the control panel. There will be a burned point in the paper, check whether the light spot is in the center of the mirror, if the light spot is not in the center o f the mirror center, we have to make the light spot in the center of the mirror by regulating the location of the laser tube. Then adjust the 1# reflector mirrors. Move the beams to the nearest place to the 1# reflector; push “Pulse” to get a spot in the paper. And then move the beams to the farthest place from the 1# reflector, get another spot in the paper. We adjust the angle of the mirrors by adjusting the three screws on the back of mirror (clockwise rotation the above screw, the spot will be down; clockwise rotation of the lower left corner of the screw, the spot will move to right; clockwise rotation of the lower right corner of screw, the spot will move to left.), to insure that all the spot are in the same place in the paper when and where the beam we move. After adjust the 1# reflector mirror well, the next, adjust the mirror 2# as we do at the first step, move the laser head to the nearest side to 2# reflector , then make a spot in the paper , then move the laser head to the farthest place to 2# , make a spot. We have to adjust the further spot overlap with the first spot by adjust the screws on the 2# reflector frame. Note: As the best, the location of light spot should be in the center of mirrors. The light spot can not hit the edges of the mirrors. If playing in the edges, please continue to adjust the m
