1.1, laser marking machine equipment ground is not good, reconnect good ground.
1.2, the computer control Board card is bad, replace the board card.
1.3, turn off the laser marker laser power supply, Q driver, with the hand gently contact the lens of the mirror whether jitter or whether the vibration mirror is howling, if the fault can be ruled out, and then one after another to open the laser power and Q drive to determine whether the laser power or Q drive caused by the fault. 1.4, if it is due to laser power caused by vibration mirror jitter or howling, laser power can be the high-voltage line and other signal lines as far as possible apart, may be signal interference, generally can be troubleshooting.
If the failure persists, replace the laser power supply. 1.5, if it is because Q drive caused by vibration mirror jitter or howling, you should check the Q drive and q switch between the connection is short circuit, the signal line short circuit will cause this fault.
If the failure persists, the Q drive can be replaced.
1.6, scanning vibration mirror is bad, replace the scanning vibration mirror. 1.7, computer operating system or computer failure, reload the system or replace the computer.
