re-check. If you are still having trouble, recalibrate the lens using the lens calibrate function in the system
tab of the UCP.
A final focusing method is to use the auto-focus feature to focus on the material. In the Cell 2 and Cell 3
laser systems, the autofocus sensor is a light beam sensor that crosses the processing area horizontally at
about 3” inches in the Y axis. There is a notch in the Y-axis ruler between the 2” and 4” marks to indicate
where the beam crosses the processing area. Make sure that a least at portion of the material to be
processed is lined up vertically with the notch blocking the light beam. If not, you may have to move the
material so it will block the light beam for auto-focus and then move it back into position for laser
processing. Then press and hold the focus button on the control panel until the autofocus process initiates.
When the Z axis stops moving the material is focused.
Important Note: Make sure the lens specified in the system tab of the UCP matches the lens installed in the
laser system when using this feature and that the Auto-Z function is enabled.
CAUTION: For this method to work correctly, the Z axis must be properly homed and calibrated to the lens
being used. To verify this, move the Z axis manually until the Z-axis position reads zero and use the manual
focus tool as described in the manual focus section above to verify that the surface of the engraving table is
at the focus plane. If necessary, re-home the Z axis using the home Z command in the UCP viewer tab and
re-check. If you are still having trouble, recalibrate the lens using the lens calibrate function in the system
tab of the UCP.
Initiating Laser Processing
Once the material is placed and focused, you are ready to initiate laser processing of the selected laser job
file. If you need to use gas assist for the material to be processed, make sure you have a Coaxial Gas Assist
Attachment (cone) or Lateral Gas Assist Attachment (backsweep) installed on the carriage and the ULS
Compressed Air Source is properly connected (see the accessories section for details). Also, ensure that your
air filtration unit is plugged into a power outlet and properly connected to the laser system. Then start the
laser job by pressing the start button on the control panel or in the UCP.
CAUTION: Make sure the air filtration unit activates and proper exhaust flow is present in the laser system
during laser processing. If proper exhaust flow is not present, damage to optics and other laser system
components can occur very quickly.
Third-Party Graphic Software Configuration
ULS Windows Printer Driver will work with a wide variety of Windows-based graphic software to create laser
jobs through the Windows Print System. Every effort has been made to make the printing process as seamless as
possible, however, to get the best results when printing through the ULS Windows Printer Driver, you should be
aware of a few general guidelines for all software as well as some specific notes regarding some of the more
popular Windows software for printing to the laser system.
Note: ULS provides no warranties or guarantees regarding compatibility with any third-party software packages
not supplied by ULS.
Note: ULS laser systems are not postscript devices and therefore are not compatible with PostScript fonts. Use
True Type fonts only.
