First, the laser head does not emit light
1. Press the test key on the operation panel to observe the current meter status: ①No current: check whether the laser power supply is connected, whether the high voltage line is loose or falling off, and whether the signal line is loose; ②Current: check whether the lens is broken and the light path is seriously offset; 2. Check whether the water circulation system is normal: ① No water supply: check whether the water pump is damaged or not powered on; ②Water supply: check whether the water inlet and outlet are reversed or the water pipe is broken; 3. Can burst, can self-check, send data without light (check whether the computer settings are correct)
Second, the carving depth is different or not deep
1. Check whether the water flow in the water circulation system is smooth (water pipes are bent or broken); 2. Check whether the focal length is normal (re-calibrate); 3. Check whether the optical path is normal (recalibrate); 4. Check whether the paper spread on the plate is too thick and whether there is too much water (correct it again); 5.

8. Common computer problems
1. The font gradually decreases (reinstall the operating system); 2. The amount of data is too large to calculate the laser path (wait a period of time or increase the computer memory); 3. The calculation path does not respond for a long time, restart the computer to test.
I. Matters needing attention
(1) When using automatic focus measurement, pay attention to that the automatic focus measurement rod must be fastened, otherwise the work surface will hit the laser head and make it off the track.
(2) When the laser engraving machine is working, it is forbidden to open the cover (top cover and front cover), otherwise the laser emission will be stopped and the processing quality will be affected.
(3) When processing the workpiece, the smoke exhaust and blowing equipment must be turned on to avoid the smoke and dust from polluting the focusing lens and reflecting lens, otherwise it will affect the focusing and reflection of the lens, thereby indirectly affecting the processing strength and processing accuracy.
(4) When processing wood and paper workpieces, you must pay close attention to the processing speed and processing intensity to avoid flames due to slow speed and high intensity. The flame will damage the focusing lens, the lighter will affect the processing strength and processing accuracy, and the heavy machine will not be used.
(5) For the initial users to process irregular workpieces, they must first perform red light positioning to determine whether the processing position is correct, otherwise it is easy to produce waste.
(6) When processing thin wood boards, cardboard and other easily deformable materials, adjust the deformation range so that the level difference is less than 1 mm to avoid excessive focus difference and affect processing accuracy. When processing the paper, the paper should be fixed to avoid displacement during work. When cutting paper, especially soft paper (rice paper, unedged paper), you can stack 15-20 sheets first, soak it with water, level it, and then cut it. This can improve work efficiency, while avoiding dangers due to material burning.
(7) When cutting, the workpiece holder should be more than 2 cm away from the work surface to avoid damage to the back of the workpiece after laser reflection, resulting in waste.
(8) Cleaning the reflective lens and focusing lens: pinch the reflective lens with two fingers, dip the camera lens cleaning paper in the cleaning liquid with the other hand, gently drag the lens surface, do not press the lens with your fingers to avoid scratches; Or use a cotton swab to soak the camera lens cleaning solution and gently wipe the focusing lens until it is smooth.
(9) Generally, when engraving vector files, the resolution should be higher (500dpi or 600dpi); when engraving dot files, the resolution should be lower (500dpi rough mode or 300dpi). This engraving effect will be very good.
Two, common faults and their solutions
(1) How to save time
When mass production of small size products of the same specification (such as a 75x25mm badge), the maximum width in the x direction should be less than 300mm, so that the laser head can be reversed faster, thereby increasing the speed. When engraving a bitmap, the resolution can be appropriately reduced to speed up the speed. In addition, the laser machining depth is directly proportional to the power and speed, that is, the faster the speed, the shallower the engraving depth under the same power situation, and the deeper the engraving depth. In this way, the speed and power should be increased as much as possible to shorten the time.
(2) How to avoid waste products
Generally, the standard configuration of laser engraving machine has red light positioning equipment. When processing irregular products, first use red light positioning to observe whether the engraving position is accurate, and then formally process. For materials that have not been seen before, the principle of power from low to high should be followed.
(3) If the machine has no laser, first check whether the magnetic switch of the upper cover, the front door and its wiring are loose or falling off (a user in Shandong, the machine was wiped clean from inside to outside before leaving work on the first night). The next morning, it was found that the machine did not emit laser light. After inspection, it was caused by the disconnection of the magnetic switch circuit when the machine was wiped). Then check the reflection and focusing lens for problems (a user in Beijing did not tighten the fixing screw after wiping the reflection lens, which caused the lens to loosen and cause no laser). If it is not for the above reasons, you must contact the maintenance personnel, please do not deal with it yourself.
(4) Large-scale engraving and cutting have different depths
This is caused by the improper laser light path. Just adjust the optical path to the right (special training is provided when purchasing the machine).
(5) Deformation of lettering body
a. If the nose trolley pulley is severely worn and the nose trolley becomes loose, replace the pulley.
b. If the belt tensions on the left and right sides of the y-axis direction are different, adjust the hexagonal screws at the rear end of the y-axis to the same tension.
c. If the driven wheel on the left side of the x-axis is worn, replace the driven wheel.
d. If the x-axis motor fails, replace the motor.
e. If the fastening screws of the x-axis motor and the pulley are loose, tighten the screws.
(6) The engraving machine engraves randomly, and the memory is in poor contact or damaged. Reinstall the memory or replace the memory.
(7) The computer interface should be set to spp
(8) Keep the data cable away from the interference source
(9) It is better to use the same socket for computer and laser engraving machine to avoid potential difference. (10) The sudden power attenuation is half of the laser tube failure, which can only be returned to the factory for repair. (11) The power decays gradually
First, check whether the reflecting lens and focusing lens are clean, and the light path is correct. If there is no problem, you should contact the maintenance personnel in time.
(12) When engraving and cutting a large area, if there are different shades, it is not a material problem. The light path must be incorrect.
(13) The automatic focus measuring rod fails
Most of them are caused by damage to the flat cable connected to it, which can be used normally after replacement.
