Initial Testing
Belt Tension
Aer all setup is completed and before you begin full use of your machine, check again that
the belts are properly tensioned and that all the wires are safely placed. See Belt Tensioning
above for details.
Emergency Stop
Because of the risk of fire and other hazards during engraving, you should test that your
laser key functions as an emergency stop before conducting any further work with your
machine. Put on your laser glasses, place a piece of laserable scrap material under the
laser head, and hold the Blink button in LaserGRBL or being running a simple pattern in
LightBurn. Turn your key o and conrm that the laser stops instantly despite the power
button remaining down. If the laser continues to re, the laser key is not working and should
be replaced before the engraver can be used. Turn off your Light and contact customer
service.
Fire Detection Sensor
Because of the risk of re during engraving, you should test that the laser
’
s infrared ame
sensor functions before other work with your machine. Make sure the button next to the re
detection sensor is UP. Put on your laser glasses, place a piece of laserable scrap material
at the far end of the bed, move the laser over it, and hold the Blink button in LaserGRBL
or begin running a simple pattern in LightBurn. Light a small candle in a safe holder and
carefully place them at the front of the bed. (You can also use a lighter but be extremely
careful to avoid burning yourself, damaging the machine, or setting re to any material.)
If the laser continues to fire after ten seconds, the sensor is not working and should be
recongured or replaced before the engraver can be used. Turn o your Light and contact
customer service.
Perform a similar test if you are using a protective cover. Begin using the laser and conrm
that it stops automatically when the door to the cover is even slightly opened.
