Step 4 - Starting the Engraving Process
•
Turn ON the exhaust system.
•
Make sure the material is positioned correctly within the engraving area.
•
Make sure the system is properly focused.
•
Make sure the top door is closed.
•
Press the START button to begin laser processing.
WARNING: Observe that the laser system is functioning as desired. If any abnormalities
are present, including but not limited to, flaming, sparking, melting, or excessive smoking
of the material you are engraving, STOP THE ENGRAVING PROCESS IMMEDIATELY
BY EITHER PRESSING THE PAUSE BUTTON OR OPENING THE TOP DOOR! Re-
check the settings in the printer driver as well as the laser system. If everything seems to
be correct, the material is not suitable for laser engraving or cutting and you MUST DISCONTINUE
processing this material or any material that may cause damage to the laser system. NEVER LEAVE
THE LASER SYSTEM UNATTENDED DURING THE ENGRAVING OR CUTTING PROCESS.
While the laser system is processing the material, you may stop the process by pressing the PAUSE
button and waiting for the system to finish what it was doing and move to the home position (upper right
corner). As long as you do not move the material inside the laser system, you can resume processing by
pressing the RESUME button. As a safety feature, if at any time you open either the top or front
door, the laser beam will shut off first, and then the focus carriage will pause and move to the
home position. However, this method of stopping the process may ruin your application material
because you will be unable to resume operation exactly where it paused.
Step 5 - Material Removing and Reloading
Once the laser system has completed processing the material, the laser beam will turn off, the focus
carriage will move to the home position in the upper right hand corner, and the green light on the control
panel will turn OFF.
Before opening the top door, wait a few seconds to let any remaining fumes that are leftover from the
laser engraving or cutting process, to evacuate through the exhaust system. Open the top door and
remove the material. Some materials will continue to emit fumes, from several minutes to sometimes
hours, after the engraving or cutting process is completed. We recommend that you relocate these
materials to a well-ventilated and unoccupied area.
WARNING: Some materials, when engraved or cut with a laser, can produce toxic and
caustic fumes. We suggest that you obtain the Material Safety Data Sheet (MSDS) from the
materials manufacturer.
processing that material.
If you start a file with the top or front door open you may notice that a red dot pointer appears on the Z-
axis table simulating where the CO2 laser beam will fire. However, please note that the red dot pointer is
NOT triggered like the laser beam itself and while the system is simulating raster engraving or vector
cutting, the area in which the Red Dot moves actually represents the complete motion of the mechanical
assembly, and is not an exact indication of where the CO2 laser beam will burn. The laser beam will be
activated somewhere within that motion depending on the graphic itself.
