Connection
Please check whether the laser module is compatible with your engraving
machine before connection.
- A. Check the voltage parameter of you engraving machine. Please ensure your engraving machine can provide at least 24V 4A power supply.
- B. Check the pin definition of the main board on your engraving machine. Please ensure your engraving machine main board has “PWM”, “GND” and “DC” ports.
-
“A” &”B”are both compatible.
Connect the laser module to the main board of your engraving machine directly .
-
Only voltage is not matched.
The voltage parameter of your machine are not matched to the module.
-
Connect the cable of your engraving machine to the corresponding input connector on P-DA-01.
-
Connect the cable of the laser module to the Output A connector on P-DA-01. Connect the 24V power adapter to the DC Input connector on P-DA-01. Push the switch to EXT
-
position and the power is provided by external power adapter.
-
Only control board pin definition is not matched.
-
Situation 1: The definition of connector on the engraving machine main board is not pin-to-pin. Please rearrange the wire sequence of the cable to make each wire is well matched with the pin definition on the main board.
-
Situation 2: Please use P-DA-01 if the main board of your engraving machine is not 3pin, such as 2pin.
LASER MODULE REFERENCE SETTINGS
For cutting
The focal length of the L T-4LDS-V1 laser module is 20mm. When cutting, you
only need to make the focus located a bit lower than th surfce of materials
.
For engraving
When engraving, please ensure that the focus is located on the engraving
material surface.
PRECAUTIONS AND MAINTENANCE
Precautions
- Please wear laser goggles to protect your eyes when you use this laser ~ module.
- Please ensure that the air pump is turned on before you start cutting. If not, the smoke will contaminate the lens.
- This laser module doesn’t support hot plug, hot plug may cause damage to the laser module.
Maintenance
- When the laser module is not used for a long time, please ensure that the lens is not polluted by dust.
- When you replace the air nozzle, please ensure that your operation will not pollut the lens. Finger prints or dust on the lens will weaken the output power of the laser module, or even damage the lens.
- When you find the cutting ability decreases, the lens might be not clean. Please use a clean alcohol swab to clean it according to the following figure.
