First, no light

1. On the old Q drive, ON, OFF, and RUN are the three gear selection errors. OFF is the forced turn-off of the laser command and ON is the mandatory light command. The correct method is to select the RUN operation.

2, bad card, change the board. The Q signal voltage on the board, under normal circumstances, the Q signal voltage is: low level when Kairui board, that is 0V when marking, 5V when not marking; gold orange card is high when marking Level, which is 5V when marking, 0V when not marking.

3, the signal connection between the board and the driver is open circuit, exchange or re-welding.

4. The light path has not been adjusted and the light path is reconstructed.

5, bad light, replace the light.

6, computer control system or computer hinder, reinstall the system or replace the computer.

7, bad laser power, replace the laser power supply.

8. The Q driver is bad, and the Q driver is replaced.

9, Q switch is bad, exchange Q switch.

Second, weak light

1. When the marking software CW method is not selected, the light will be weak and the CW method will be selected.

2. The wrong position of M1, M2, and M3 on the Q driver is selected. The correct method is to select M1.

3, focal length error, re-medal focus.

4, the water temperature is too high.

5, xenon lamp aging, replace the xenon lamp.

6, all-trans or semi-reflective lenses, focusing lenses, oscillating lenses, Q switch lens dirty or rub flowers. Clean or replace.

7, cavity, total reflection mirror, half mirror and beam expander did not adjust well, re-mediate.

8, Q switch is not adjusted well, the normal situation is marking light, do not mark the Q switch to lock the laser. The current of the laser power supply can be adjusted to be larger, and the frequency doubling chip is placed in front of the half mirror to see if there is any light leakage. If it leaks light, the light will be very weak, and mediate the Q switch again.

9, the laser did not hit the galvanometer center, or galvanometer lens scratches. Re-adjust the light path or replace the galvanometer.

Third, continuous light

1, the wrong switch sequence may cause continuous light. The correct power-on sequence is: Total power supply => Computer => Marking software => Chiller => Q drive => Laser power supply => After READY lamp on equal power supply => Press RUN button to start => Mirror power switch . The order of shutdown is the opposite.

2. The ON, OFF, RUN gear switch on the old Q driver is wrongly set, ON is the forced light command, and OFF is the forced turn off of the laser command. The correct method is to select RUN.

3, bad card, change the board. Kairui board should also pay attention to the jumper cap above the board: YAG50 jumper cap should jump T end. (Be sure to pay attention to this issue when replacing the Kai Rui board)

4, Q switch is not adjusted well, the normal situation is when the marking light, do not mark the Q switch to lock the laser.

6, if Kai Rui software may also be due to marking software problems, resettle.

7, computer or operating system problems. Exchange or reinstall the system.

8. The Q driver is bad, and the Q driver is replaced.

9, Q switch is bad, switch Q switch (this situation is less, in general, Q switch is broken, Q drive will alarm)

Fourth, galvanometer does not move

1. The parameter X, Y ratio mediation option on Kairui software is zero, and the galvo mirror will not move and re-adjust the parameters.

2, bad card, change the board. The voltage of X and Y galvanometer signals on the board is normal: 0-5V is changed during marking, and 0V is not used when marking.

3, galvanometer signal line open, exchange.

4, Qinlong galvanometer, the driver on the jumper cap next to the signal indicator must be dialed, or galvanometer will not move.

5, galvanometer obstruction, exchange galvanometer.

6, computer control system or computer hinder, reinstall the system or replace the computer.

Five, galvanometer jitter and howling

1, the ground is not connected, re-connect the ground.

2, bad card, change the board.

3, turn off the laser power supply, Q drive, gently touch the lens of the galvanometer if the lens is shaking or whether the galvanometer is whizzing, if it blocks the exclusion, then turn on the laser power and the Q driver one by one to determine whether the laser power or the Q drive is caused .

4, if it is because of the laser power supply caused by galvanometer jitter or whistle, the laser power supply high-voltage line and other signal lines as possible to leave some, in general, will obstruct the exclusion. If the obstruction still exists, replace the laser power supply.

5. If it is because the Q driver causes the galvanometer to shake or whistle, you should check whether the connection between the Q driver and the Q switch is short circuited. Short circuit of the signal line may cause this obstacle. If the hindrance still exists, swap the Q drive.

6, galvanometer bad, exchange galvanometer.

7, computer control system or computer obstacles, reinstall the system or replace the computer.

Six, Kai Rui marking software will automatically turn off after opening

1, dongle is not installed, resettle.

2. The driver of the dongle is not installed and the driver is relocated.

Seven, the marking effect is not good

1. The reason for marking the software or system. Reinstall the system or marking software.

2. The parameters of the marking software are not adjusted properly, and the parameters are reconstructed.

3, the focal length is not adjusted well, refocus the focus.

4, marking the graphics did not do a good job or marking material is not allowed.

Eight, graphics deformation

1, the graphics themselves do not do a good job, redo.

2, the parameters are not adjusted, re-mediation distortion correction inside the pillow-shaped bulge and level straight more positive.

3, galvanometer did not adjust well. Reconciliation.

4, Marking software or system problems, reset the marking software or system.

5, bad galvanometer, exchange galvanometer.

Nine, the wrong size

1. The size of the exported graphic itself does not match the required graphic size, and the picture is redrawn. Simple graphics can use marking software to make new dimensions even easier.
