laser engraver for wood and metal
The laser intensity is dropped and the mark is not clear enough:
1.Whether the laser resonant cavity changes, the resonant cavity lens should be finely adjusted to make the output light spot optimal;
2.If the acousto-optic crystal is shifted or the output energy of the acousto-optic power supply is low, the acousto-optic crystal position should be adjusted or the working current of the acousto-optic power supply should be increased.
3.If the laser entering the galvanometer is off-center, the laser should be adjusted;
4.If the light intensity is still not strong enough when current is adjusted to about 20A, please contact our after-sales service for assistance.
1.1.The lens is dirty: use a cotton smeared with a little alcohol and then gently wipe the lens ;
2.Marking speed is too high: reduce the speed and increase the density of filling;
3.The power is not turned on or the power supply current is too small: the power supply current should be turned on, or increase the power of the current.
4.Laser has a certain service life span. It may be expired and the laser need to be replaced.
