If there is no laser for your LaserPecker 4 (LP4) during Preview or Engraving. Follow the instructions below before contacting the LaserPecker Support Team. Always follow standard safety protocols when testing even when no laser beam is apparent.
1. Check the Lens
A plastic cover is used to protect the lens while in transit. Make sure to remove it before attempting to use your LP4.
2. Check the Focal Length
Improper focus may result in insufficient energy for engraving. Although the LP4's standard focal length is 150 mm, the optimal focal length for each unit's lens may vary slightly. To achieve optional engraving results, it is recommended that you test your LP4 to find the exact focal distance. Set the focal length to 150 mm and adjust the height +/- to precisely dial in the distance for your machine.

3. Check the Laser Source
The LP4 is equipped with a 450nm Blue Diode and a 1064nm Infrared laser. Select the appropriate laser for the material that you are working with by sliding left or right on the unit's built-in screen and from the LDS App and LDS Software settings menu. Make sure the type of laser selected is the same.
450nm Blue Diode Laser:
After switching to "Preview" mode during normal operation, a straight blue beam should be emitted onto the working surface. If there is no visible laser output after checking steps 1 and 2 above, please contact the LaserPecker Technical Support Team at support@laserpecker.com.
1064nm Infrareds Laser:
The beam is invisible during engraving and suitable for engraving metals and plastics. Please make sure the material to be engraved is applicable. If engraving still doesn't work even on applicable materials, consider increasing engraving parameters before retrying.
