7. Confirm the emergency button works fine.
Because of the risk of fire and other hazards
during engraving, this machine includes a
large and easy-to-reach emergency stop
button on its control panel. Press it down to
stop the laser instantly. You should test that
it works properly before conducting ANY
other work with your machine.
a. In EZCad, press Mark or hit F2 to fire the
laser. Alternatively, use the foot pad.
b. While the laser is still active, hit the
emergency stop button and observe
whether the laser stops instantly. If the
laser continues to fire, the emergency
stop is not working and must be replaced
before the machine can be used. Turn off
the machine, replace the lens cap, and
contact customer service.
8. (Optional) Attach and test any other equipment—particularly safety equipment such as 15-pin
protective enclosure—in similar fashion before beginning work.
If you will use the bracket to hold a computer display on the support column, be sure to use
two people for heavier monitors. One should tighten everything carefully while the other fully
supports the weight of the monitor. When you are finished, only slowly release the support as
you safely confirm both that the monitor's weight will be supported and that it will not affect the
balance of the support column.
Confirm again that all cords and cables will present no tripping hazard and do what you can
to limit unauthorized access to the laser, including installing locks on its room and password
protecting the control computer.
9. Turn off the laser marking machine from bottom to top in order:
a. Press the LASER button to turn off the fiber laser source.
b. Turn the GALVO access key to turn off the galvo head.
c. Push down the emergency stop button to turn off the mainboard.
Again, wait about 3 seconds between each step to allow each system to safely disengage.
10. Cover the galvo lens cap.
