Common malfunctions of advertising engraving machines include:

1. Turn on the power, but the indicator light of the controller does not light up. This may be caused by issues such as blown fuses or poor contact. At this point, it is necessary to check whether the components on the circuit board are normal, replace damaged parts in a timely manner, or carry out corresponding repairs.

2. The control card has no display and communication is abnormal. These may be related to the data connection cables, and you can try cleaning or unplugging the data cables to determine if the problem is caused by loose interfaces. It may also be caused by issues with the control card settings and require adjustment.

3. Sudden stop or failure to execute commands while the nose is running. There may be multiple reasons for this situation, such as cutting too small or too much material causing excessive heat and triggering the temperature control switch to trip; Unstable voltage or short circuit can also cause the machine to malfunction; This situation may also occur if the friction between the X-axis and the guide rail is too tight. Therefore, it is necessary to promptly shut down the equipment and conduct inspections and repairs to address these issues.

4. Dimensional deviations that occur during the engraving process. This issue may be caused by tool wear and requires adjustment and management of the tools. Sometimes material quality issues may also affect the final result.
