When LP4 start engraving without any laser emission, you may troubleshoot by following the instructions below.
Check Field Lens
Make sure its lens cover has been removed. The cover is used to protect the field lens before delivery.
Check for correct focusing, since improper focusing may result in insufficient laser energy for engraving.
You can check the link below for more information about focusing:
Check Laser Source
Check if the current laser wavelength is 450nm or 1064nm.
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.
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.
