Common faults and their handling methods
(1) How to save time
When making a large number of small-size products of the same specification (such as 75x25mm badges), the maximum width in the X direction should be less than 300mm, which can make the reverse speed of the laser head faster, so as to improve the speed. When engraving dot matrix, the resolution can be appropriately reduced to speed up the speed. In addition, the depth of laser machining is directly proportional to the power and speed, that is, the faster the speed is under the same power, the shallower the engraving depth is, on the contrary, the deeper it is. In this way, we should try to improve the speed and power to shorten the time.
(2) How to avoid waste products
The standard configuration of general laser engraving machine includes red light positioning equipment. When processing irregular products, first use red light to locate and observe whether the engraving position is accurate, and then carry out formal processing. For materials that have not been seen before, the principle of power from low to high should be followed.
(3) Machine without laser
First check whether the magnetic switch and its circuit of the upper cover and front door are loose or fall off (a user in Shandong wiped the machine from inside to outside before leaving work the first night. The next morning, it was found that the machine did not emit laser, which was caused by the falling off of the magnetic switch circuit when cleaning the machine). Then check whether there are problems with the reflection and focusing lenses (a user in Beijing did not screw down the fixing screws after wiping the reflection lenses, resulting in loose lenses and no laser). If it is not for the above reasons, you must contact the maintenance personnel. Please do not handle it by yourself.
(4) The depth of large-area carving and cutting is different
This is caused by incorrect laser light path. Just adjust the optical path correctly (there is special training when purchasing the machine).
(5) Engraved font deformation
A. If the head trolley is loose due to serious wear of the head trolley pulley, replace the pulley.
B. If the belt tension on the left and right sides of the y-axis direction is different, adjust the hexagon screw at the rear end of the y-axis to the same tension.
C. If the driven wheel on the left side of x-axis is worn, replace the driven wheel.
D. Replace the x-axis motor if it fails.
E. If the fastening screws of x-axis motor and pulley are loose, tighten the screws.
(6) The engraving machine engraves randomly, and the memory is in poor contact or damaged. Reinstall or replace the memory.
(7) Computer interface to be set to spp
(8) The data line shall be far 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) Half of the sudden power attenuation is due to the failure of the laser tube, which can only be returned to the factory for maintenance.
(11) Gradual power attenuation
First, check whether the reflecting lens and focusing lens are clean and whether the optical path is correct. If there is no problem, contact the maintenance personnel in time.
(12) When carving and cutting in a large area, the depth is different, if it is not a material problem. Then the light path must be incorrect.
(13) Automatic focusing rod failure
It is mostly caused by the damage of the flat cable connected to it, which can be used normally after replacement.
