How to Deal with Laser Marking Machine Failure?

When there is a problem with the laser marking machine, if the problem cannot be solved in time, it will affect the delivery time of the product. Although the maintenance of the laser marking machine is more troublesome, its principle is relatively simple. For example, metal laser marking machine manufacturers list several common faults for you, which do not require professional and technical personnel to repair, and many problems can be solved by themselves.

Common fault 1: The laser scanning part does not respond.

Possible reasons: 1. The scanning power button is not activated; 2. The laser indicator is damaged; 3. The field lens cover is not removed; 4. The signal is not connected well; 5. The computer software or system is faulty.

Corresponding solutions: 1. Turn on the scanning power switch, 2. Replace the laser indicator light; 3. Remove the field lens cover; 4. Restart and reconnect the signal cable; 5. Restart the computer or reinstall the computer system.

Common fault 2: Some parts of the marking are clear and some places are not clear.

Possible reasons: 1. The marking surface is not parallel to the field lens; 2. There are stains on the surface of the field lens; 3. The workpiece itself is stained or uneven.

Corresponding solutions: 1. Adjust the marking surface to be parallel to the field lens; 2. Clean the surface of the field lens; 3. Avoid unevenness when cleaning the workpiece or marking.

Common fault 3: The marking depth is not enough.

Possible reasons: 1. The power percentage setting is too small; 2. The workpiece surface is not on the focal plane; 3. The marking speed is too fast; 4. The power output is unstable.

Corresponding solutions: 1. Increase the power percentage; 2. Adjust the height of the workpiece on the focal plane; 3. Appropriately reduce the marking speed; 4. Ensure that the output power of the power supply is stable.

Common fault four: galvanometer lens marking distortion.

Possible cause: Pincushion or barrel distortion on the square border.

Corresponding solution: use the attached software for data correction.

Common fault five: The software prompts that the control card cannot be found.

Possible reasons: 1. The board slot is loose; 2. The driver is deleted.

Corresponding solutions: 1. Shut down and re-insert the board; 2. Install the driver.
