I. Suddenly no light during the cutting process of the machine
1, check whether the water tank alarm
A. Alarm. Connect the water inlet and outlet of the water tank with a water pipe. If the alarm is reported, the water tank is broken. If it is not alarmed, the laser tube is not clear. Check whether the water tube is bent or pressed by something, and whether there is any debris in the water tank (replace the pure water in the water tank).
B. No alarm, check if the Laser Engraver power fan is running. The laser power fan is turned, and the laser power is shorted with a wire.
2. If the laser tube emits light, the wire on the motion control card is loose, or the motion control card is broken (replace the board). No light, laser power is bad. (In rare cases, the laser tube is broken.) (Check whether the high-voltage end of the laser tube is ignited. It is easy to burn out the laser power supply and the electronic components of the board). The laser power fan does not turn. Use an electric pen to test the laser power 220V port for power. There is electricity, and the laser power is bad. (Repair or replace the power supply); no power, check the laser power switch and wiring.
2. The light does not come out when the machine is turned on.
Check the following aspects
1. Whether the Laser Engraver power switch is on.
2, whether the water tank is open.
3. Whether the power of the machine operation panel is correct. Or the computer software parameters are correct.
4. Whether the light path is normal. (Press the light to see if the laser tube is on. If the laser head is off, there is a problem with the light path.)
