Laser engraving machine troubleshooting methods and machine operation guide

1. Machine processing methods for common faults of laser engraving machines

How to be more efficient?
When producing a large number of small-sized products of the same specifications, such as 80*30mm, this can make the laser head move back and forth faster, thus increasing the speed. When engraving bitmaps, the resolution can be appropriately reduced to speed up the process. In addition, the laser machining depth is proportional to the power and speed. That is, the faster the speed, the shallower the engraving depth will be with the same power, and vice versa. Therefore, the speed and power should be increased as much as possible to shorten the time.

How can we save costs?
Generally, the standard configuration of laser engraving machines includes red light positioning equipment. When processing irregular products, you should first use red light positioning to observe whether the engraving position is correct before proceeding with formal processing. For materials that have not been seen before, the principle of power from low to high should be followed.

What should I do if the machine does not have a laser?
First check whether the circuit of the magnetic switch on the front door of the upper cover of the laser engraving machine is loose or falling off, and then check whether there are any problems with the reflection and focusing lenses. If it is not for the above reasons, you must contact maintenance personnel, please do not handle it yourself.

What is the reason for large-area carvings and uneven cutting depth?
This is caused by the incorrect laser path. All you need to do is adjust the optical path. Special training is provided when purchasing equipment.

What should I do if the engraved font is deformed?

—If the machine head trolley pulley is severely worn, causing the machine head trolley to become loose, replace the pulley.
—If the belt tension on the left and right sides of the Y-axis direction is different, adjust the hexagonal screw at the rear end of the Y-axis until the tension is consistent.
—If the driven wheel on the left side of the X-axis is worn, replace the driven wheel.
—If the X-axis motor fails and the fastening screw of the pulley is loose, tighten the screw.
—If the fastening screws between the X-axis motor and the pulley are loose, tighten the screws.
—The engraving machine engraves randomly, and the memory has poor contact or damage. Reinstall the memory or replace the memory.
—The computer interface must be set to SPP
—Laser engraving machine data cable should be kept away from interference sources
—It is best to use the same socket for the computer and laser engraving machine to avoid potential differences.
—The sudden loss of power by half is a laser tube failure and can only be returned to the factory for repair.
—The power of the laser engraving machine gradually decreases
First, check whether the reflective lens and focusing lens are clean and whether the optical path is straight. If there is any problem, please contact the maintenance personnel in time.
—When engraving and cutting large areas, the appearance of different shades is not a material problem. Then the light path must be incorrect.
—The automatic focus rod of the laser engraving machine fails. This is mostly caused by damage to the flat cable used to connect it. It can be used normally after replacement.

2. Simple operation guide for laser engraving machine

After the processing files are arranged, the processing position can be selected, and the software can be used for high-speed processing speed, processing intensity and processing accuracy. If processing is to be affected, the corresponding grid must be set. After the adjustment is completed, the frame must be output first to determine the position of the workpiece on the table, and then the workpiece is placed. After placing the workpiece, press the output key in the software and wait for the laser engraving machine to Receive the file. After the engraving machine receives the file, you can press the start button to perform red light positioning, and then press the start button for processing.
