How to troubleshoot laser marking machine encountering inability to cut in

There are several reasons and troubleshooting methods:

1. When the vertical light is incorrect, please adjust the vertical light and readjust the light path if necessary.
2. If the focal length is not adjusted properly, please refocus.
3. The voltage is unstable, the voltage is low, and the laser current is too small. You need to replace a larger voltage regulator and increase the laser current output.
4. If the light outlet of the air nozzle is blocked by splashes, the air nozzle should be cleaned in a timely manner.
5. To protect against air blockage, it is necessary to clean the air pump, air filter, and air circulation path.
6. After the reflector and focusing lens are contaminated, clean them with cleaning solution.
7. Check if the laser tube is powered off, and if so, replace the laser tube.
If the LED control module on the motherboard malfunctions, replace the motherboard directly.
9. There is a potentiometer device. If the potentiometer setting is too small or it malfunctions, adjust the potentiometer setting or replace it.
10. The energy setting in the software is too small, please increase the energy.
11. Regarding material issues, please choose the appropriate material.
12. If the focusing lens has cracks or poor focusing effect, replace the focusing lens directly.
13. The laser tube has too much dirt and poor heat dissipation effect. The cooling water must be pure water or distilled water.
