3.10 Initial Testing
Emergency Shuto
Because of the risk of re and other hazards during engraving, this engraver includes a
large and easy-to-reach emergency stop button near the control panel. Pressing it down
stops the laser tube instantly.
When your engraver arrives, its e-stop is already pressed and must be rotated up to
allow the laser to function. You should test that it works properly before conducting
ANY other work with your machine.
Warning! Always check that the chiller has laser-safe antifreeze or distilled water
lled to the “Normal” before ipping any of the circuit breakers on the engraver.
If there is none or the chiller is underlled, screw open the port and infuse laser-
safe antifreeze or distill water to ‘Normal”.
Laser Key
1. Flip both circuit breakers on. Visually conrm that water is owing through the entire tube and all air bubbles
have been removed and that the power indicator is on.
2. Place a piece of laserable scrap material on the workbed under the laser head and close the cover.
3. Twist the emergency stop clockwise to release it and turn the ammeter knob fully clockwise if it is not already in
that position.
4. Insert and turn your laser key to activate the laser power supply.
5. Tap the box next to Power in Parameter Display Area from the main menu. Set reset the maximum and minimum
laser power to 12%. Tap OK to conrm the modication and exit the current menu.
