WATER CUT-OFF.
Due to the dangers posed by uncooled laser tubes, the engraver also
automatically shuts down the laser when the water cooling system fails.
After making sure that both the emergency stop button and the lid protection
are working properly, you should also test that the water cut-off is working
properly before doing any other work on the machine. Start the water cooling
system, place a piece of laserable scrap on the work bed, close the lid, and
press PULSE to fire the laser. Release the button. Cut off the flow of water by
curling or tying two hoses. Be careful not to damage the hose itself during this
process. Try firing the laser again. If the laser is emitted, the automatic shut-off
does not work and must be repaired before using the engraver. Turn off the
machine and contact customer service. If the laser does not emit, the
automatic shut-off works fine; Simply loosen both hoses to start circulating
water again and continue setting up the engraver.
LASER PATH CALIBRATION.
While our factory calibrates your entire system during assembly, the laser tube,
focusing lens, and/or one or more mirrors may be pushed out of alignment
during shipping. Therefore, it is recommended that you perform an optical
alignment-test when setting up your machine. For step-by-step guidance, see
the maintenance section below.
