In case of equipment failure and disorderly engraving of a CO2 laser cutting machine, first at all, check the laser tube or high-voltage wire. Secondly, please check whether the machine is not grounded or subject to other interference. If the problem is still unsolved, please contact the after-sales department for technical guidance or repair, dial +86-13925872583.

If the laser tube of a CO2 laser cutting machine cannot produce light, the possible reasons are:

1·The laser parameters are not correctly set

2·High voltage connector is not connected properly

3·Poor connection of laser control wire

4·The laser power supply is damaged

5·The laser tube is damaged

If the problems still cannot be solved, please contact with the after-sales department of Han's Yueming Laser Group, which will provide you with excellent technical guidance and support.

When this situation happens while a CO2 laser cutting machine is working, the first thing to do is checking whether the problem is caused by the improper setting of the motion parameters, or by the damage of the driver or motor, the broken wiring or poor contact of the motor. If you have any others questions about how to use this machine, please feel free to contact our professional engineers.

when this situation happens in the operating of a CO2 laser cutting machine, the possible reasons are:

1·Make sure that the zoom percentage in HGPL output dialog box of CorelDRAW is set as 100%

2·The pulse equivalent should be correctly set

3·The main board is not grounded or subject to other interference

4·The temperature of working environment is too high

The laser marking machine from Han's Yueming Laser requires a maintenance file to better provide after-sales service for the customers.

1、 Strongly suggest customers to establish a daily maintenance file;

2、 Find out the problems from customers’ maintenance files;

3、 According to the operation manual, check if users master the entire operation;

4、 Evaluate users’ operation, and provide suggestions and guidance according to “Equipment maintenance and precautions” manual

If problems detected in the optical system of a laser marking machine, the possible reasons are:

1、Check whether the outlet of the laser tube is polluted;

2、Make sure the laser tube is installed firmly;

3、Confirm the optical path and focus is set correctly

4、Make sure that the lens are installed firmly and correctly;

5、Check whether the lens is polluted or damaged;

6、Make sure that the selection of the focus lens is appropriate, according to the processing characteristics;

7、Connect the ammeter, adjust the light intensity, and check whether the laser tube can work normally.

If this situation happens while a laser marking machine is working, please try the solutions below. Also, you can dial +86-13925872583, and contact the after-sales department.

1、Make sure that the air pipe is not bended;

2、Check whether the air pipe is damaged or leaking; Make sure that air can be easily conveyed through air pipe;

3、Check whether the equipment is clean and make sure the moving parts are all lubricated;

4、Check whether all mechanical parts are loose; Confirm that the belt tightness is appropriate;

5、Make sure that the verticality, straightness and flatness are qualified;

6、Shut down the machine, push the beam and laser head manually, and check whether the movement is smooth;

7、Turn off the laser and all kinds of noise sources, turn the equipment on to the highest speed for operation, and check whether the equipment operates normally and confirm that there does not exist any abnormal sound;

8、honeycomb plate is flat and the lens is well installed; Check whether the beam is in the right position.

9、Make sure the exhaust fan and air duct are clean and make no abnormal noise. Check whether the filter in the air pump is clean.

The failure causes of the chiller of a laser marking machine are listed as below:

1、The water in the chiller is not clean or the temperature is too high or too low;

2、The water tube is bent;

3、Water seepage or leakage exists in the water system.

4、 Make sure that the water can be convoyed smoothly and the filter sponge in the water pump is clean.

If the problems are still not solved, please dial +86-13925872583, for after-sales service。

Two ways we can apply:

1、The whole machine (Electric Cabinet, Mechanical Drive, Worktable, Collection Box, Laser Tube or Laser Generator)

2、Auxiliary equipment (Chiller, Blower, Air Pump)

Please dial +86-13925872583 for detailed consultation about the problems that occur during the operation, and professional engineers will answer them for you.

当激光雕刻机在工作时出现画圆成椭圆、画圆不圆、画圆变形等问题处理方法如下：

1、检查XY轴的步距、脉冲当量或分辨率是否正确 重新计算准确值；

2、机械部分问题，同步带是否磨损，X向皮带松紧是否适宜；Y向皮带松紧是否适宜、两侧张紧程度是否相同；横梁方面（是否扭曲，平行度是否符合标准）等方面进行分析。X向、Y向传动部分的轴承是否磨损，联轴节是否松动；

3、XY轴驱动器部分问题，驱动器是否运行正常，拨码是否正确；

If the engraving depth of a laser engraving machine is substandard, several things we need to pay attention to:

1.Check whether the laser intensity, speed and water temperature are in normal value;

2.Make sure the edge depth is normal. If it is normal, increase the graphic resolution or scanning accuracy;

3.If the edge is still very shallow, check whether the lens is dirty or damaged, and the optical path is offset;

4.Connect the ammeter to see if the current can reach 20mA. But if the depth is not enough, it means the laser tube is aging, and a new laser tube is required.

If these situations happen while using a laser engraving machine, following solutions can be adopted:

1.Check whether the LCD or fluorescent lamp of the machine is working properly. If not, examine the power supply system or main power fuse;

2.If the LCD or fluorescent lamp of the machine is working properly, check the motherboard parameters of the new model. Change it if the parameters are incorrect;

3.If the two solutions do not work out, the main board or drive may be malfunctioning
