8.1 No Laser Beam Output

If there is no laser output when Beambox is running and making a loud cracking sound, it indicates the tube is broken. Please stop operating the machine to prevent further hardware failure.


If you do not hear the cracking sound, please check the following:
1. Open the back lid, refer to Laser Tube Replacement for instructions.
2. Go to control panel > Maintenance, make sure power is set to "x1.0" then close the front door.
Press “Laser Pulse” and observe if a pinkish fluorescent light is emitted. If yes, it means the laser tube is functioning, please check the optical path. If no pinkish fluorescent light is observed, please contact FLUX Support.
