Common faults and solutions of laser engraving machine

1. The laser head does not emit light
1. Press the test key on the operation panel to observe the status of the ammeter: â‘  No current: check whether the laser power supply is turned on, whether the high-voltage line is loose or detached, and whether the signal line is loose; â‘¡ there is current: check whether the lens is broken or the optical path is seriously shifted; 2. Check whether the water circulation system is normal: â‘  No water flow: check whether the pump is damaged or not powered; â‘¡ Water flow: check whether the water inlet and water outlet are reversed or the water pipe is broken; 3. Can be fired, self-check, and the data sent does not emit light (Check if the computer settings are correct)

Second, the depth of carving is different or not deep
1. Check whether the water flow of the water circulation system is smooth (the water pipe is bent or the water pipe is broken); 2. Check whether the focal length is normal (recalibrate); 3. Check whether the optical path is normal (recalibrate); 4. Check whether the paper on the plate is too thick , Whether the amount of water is too much (re-correction); 5. Check whether the beam is parallel (adjust the belts on both sides); 6. Check whether the lens is broken (replace); 7. Check whether the emitting end of the lens or laser tube is contaminated (re-clean); 8 1. Check whether the water temperature is higher than 30 ℃ (replace the circulating water); 9. Check whether the laser head or focusing lens is loose (tighten); 10. The laser current light intensity must reach 8mA; 11. The laser tube is aged 3. Reset is abnormal
1. Check whether the sensor is stained with dust, poor contact or damage (clean the dust on the sensor or replace it); 2. Check whether the flexible conductive tape data cable has poor contact or damage (trim the data cable and replug or replace the data cable); 3. Check whether the ground wire contact is reliable or the high-voltage wire is damaged (re-ground or replace the high-voltage wire); 4. Poor contact of the motor wire.

4. Missing
1. The initialization is incorrect, the data has been sent (corrected); 2. The operation sequence is reversed (re-output); 3. Static interference (check whether the ground wire is off);

Fifth, the cleaning edge is misaligned and not closed
1. Whether the edited file is correct (re-edit); 2. Whether the selected target is beyond the publishing surface (re-select); 3. Check whether the software parameter setting is correct (re-set); 4. The computer system is wrong (re-install the operating system) And software); 5. Check whether the tension of the left and right belts is consistent or the back end belt is too loose (belt tightening); 6. Check whether the belt or the synchronous wheel slips and skips teeth (tighten the synchronous wheel or belt); 7. Check whether the beam is parallel (Readjust the left and right belts);

6. The computer cannot output
1. Check whether the software parameter settings are normal (reset); 2. Whether the engraving machine starts according to positioning before outputting (re-output); 3. Check whether the machine has not been reset in advance (re-correction); 4. Check whether the output serial port is compatible with the software Set the serial port to be consistent (reset); 5. Check whether the ground wire is reliable and whether static electricity interferes with the data line (reground); 6. Replace the computer serial port output test; 7. Reinstall the software and reset the test; 8. Format the computer system Disk reinstallation software test; 9. The serial port of the motherboard is damaged and needs to be repaired or replaced.
