Laser debugging
Laser debugging contains two aspects: light emitting test and light route adjustment. The followings are the
details for them.
3.3.3.1
Light emitting test
After normal power up, press the laser power switch on the right side cover, and then set the light emitting
energy and time directly on the control panel, and test if the laser emitting function is normal.If there is no laser
emitting from the spot spray laser tube, it means that there is problems with the laser emitting, and check is
required. In case of laser emitting found from the laser tube, but no laser emitting from the cutting head, it means
improper position of the light route, and adjustment of light route is needed.
If there is no laser emitting, first check the setting of laser parameters. Improper laser parameters may cause
equipment malfunction or laser power cannot be adjusted. If the laser parameters are determined correct and
there is no emitting still, you need to check the hardware problem. You can use the red “TEST” button on the back
of the laser power to test if the laser power and laser tube are normal, as shown in Figure 3-7. When there is no
laser emitting, unplug the main board control wire from the laser power, turn on the laser power, and press the
“TEST” button in the front of the laser power. If the glass tube has laser emitting at this time, it indicates that the
laser power and laser tube work properly. In this case, check if the main board and laser control line of the main
board are normal. If there is no laser emitting still, further check the laser power or laser tube.
Tips
The control panel of some types of machine is equipped with ammeter. With the
ammeter, you can check if the power is normal. Theoretically, the maximum power of
80W laser tube is corresponding to the current roughly 25mA, and the 130W laser tube to
30mA of the current
3.3.3.2
Light route adjustment
Due to vibration during transportation, aberrancy of light route may possibly be caused. At this time, light
route correction is needed.
