The position deviation of Y-axis is large

Laser cutting machine Y-axis position deviation is large: 1.Check whether the motion controller in the computer is loose, or too much dust; 2.Check whether the servo drive is alarming; 3.Check whether you can push the crossbeam by hand. If you cannot solve the problem, please call the after-sales phone for technical guidance or repair, after-sales phone: +86-13925872583

No beam generated from laser head

The operation is closely related to the daily maintenance and inspection. Find the problems as soon as possible and implement effective measures to solve the problems. If the problem cannot be solved in the following ways, you can contact the after-sales department.

1、The laser generator power supply voltage exceeds the range: the laser power supply is unstable, restart the laser generator

2、Check whether the laser generator start, red light, optical shutter is on in the software

3、Check whether there is alarm information in the laser monitoring page and software.


Incomplete process of laser cut

If there is incomplete processing, missing cutting or less cutting and other problems, you can try to select graphics button in the operating software, if still cannot use the machine, please contact the after-sales phone: +86-13925872583

Laser is intermittent during cutting

When laser is intermittent during cutting, first of all, check whether the laser path is in the middle of the nozzle, and it is possible that the external control module of the laser is broken. Any question, please call for the consultation, a professional engineer will answer you.

Stop cutting or shake during cutting

Check as the following steps

1、1.Check whether the coupling between the X-axis motor and the lead screw, and the coupling between the motor and the reducer  are loose

2、2.Check whether the connection between the driver and the servo motor is broken or poor contact; check whether the connection between the terminal board and the servo driver is broken or poor contact

3、3.Check whether the metal sheet is flat


Maintenance File

Create the maintenance file which is convenient for users to check the use of the machine.

1、 Advise to create routine maintenance files.

3、 Follow the Manual, check the operation proficiency.

4、 Follow Maintenance and Precautions, check the implementation and provide guidance


Equipment failure

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.

No laser beam comes out from the laser tube

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.

Motor shaft does not move or vibrates

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.




The size of PLT graphic does not fit

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




Maintenance File

Engraving circle into ellipse & Engraving circle out of shape

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;


Substandard engraving depth

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.




Turn on but no movement & Operate but no response

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
