Check Laser Source
Check if the current laser wavelength is 450nm or 1064nm.
For 450nm:
A straight blue beam will be emitted in preview mode. If you've finished step 1 and step 2, but there's still no laser output, please kindly contact LaserPecker Technical Support for advice.
For 1064nm:
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.
Tips:
For wood, paper, bamboo, food, genuine leather, etc., please choose the 450nm laser:
For metals and plastics, please choose the 1064nm laser:
