3.10 Initial Testing
Emergency Shutoff
Because of the risk of fi re and other hazards during engraving, this engraver includes a large and easy-to-reach
emergency stop button on the control panel. Press it down to stop the laser tube instantly.
When your engraver arrives, its e-stop should be pressed down and must be released to allow the laser to function.
You should test that it works properly before conducting ANY other work with your machine. Start the water cooling
system, place a piece of laserable scrap material on the workbed, close the cover, and fi re the laser. Hit the emergency
stop button and observe whether the laser stops instantly. If the laser continues to fi re, the emergency stop is not
working and must be replaced before the engraver can be used. Turn off the machine and contact customer service.
Cover Shutoff (Interlock)
Because of the risk of blindness, burns, and other injury from direct exposure to the invisible engraving beam, this
device also shuts off the laser automatically when the protective cover is raised during operation.
After ensuring that the emergency stop button works, you should also test that the cover shutoff works properly
before conducting any other work on your machine. Start the water cooling system, place a piece of laserable scrap
material on the workbed, close the cover, and fi re the laser. Release the button. Taking care not to expose yourself to
seeing or being hit by any possible refl ected laser light, open the cover as little as possible and attempt to fi re the laser
again. If the laser fi res, the automatic shutoff is not working and must be repaired before the engraver can be used.
Turn off the machine and contact customer service.
Laser Path Calibration
Although our factory calibrates your entire system during assembly, it is possible for the laser tube, the focus lens,
and/or one or more of the mirrors to be jostled out of alignment during shipment. As such, it is recommended that
you perform an optical alignment test as part of setting up your machine. Be especially mindful NOT to look at the
laser directly during this initial process. See the Maintenance section below for step-by-step guidance.
