1. Make sure that the machine has successfully connected to the laserGRBL software of the computer. Because when the connection is not successful, the laser module cannot emit laser light.
2. Check whether the motor cable is installed correctly. (you can try to reinstall)After being connected correctly, the fan on the laser module will rotate.
3. If the fan does not rotate, open the main control box and find the laser interface, and check whether the cable is disconnected, "+12v-" and "+TTL-" (you can try to reinstall the cable).Inserting the wrong port will also cause no light, so you need to check: Are these 2 ports installed correctly?Correct: "+TTL-" cables have 1 wire, and "+12v-" cables have 2 wires.
4. If the fan is rotating.Please check: whether the cable of the "+TTL-" interface can conduct current, and only when the current is conducted can the laser be emitted.Please let us know if this cable is damaged.
5. If the cable is normal and the fan is normal, perform the following steps:Let the machine start engraving and check if there is a new flashing light on the control PCB board.If so, it means that the main control board is sending signals to the laser module, and the cable is fine. Possible result: the laser module is faulty.If there is no flashing light, it means that the software on the computer has not turned on the M3\M4 mode or the power value is set to 0.How to solve: Modify the power value or reinstall the LaserGRBL software.
6. If none of the above steps solve the problem, re-refresh the machine firmware.

1. Check: In the laserGRBL software, when loading the pattern, is the setting value of S sufficient?Please set the maximum S value to 1000, and then perform the engraving test again.
2. In the laserGRBL software, enter $30=1000 in "type gcode here", and click the "Enter" key on the keyboard. Then do the engraving test again. (This is to set the default maximum power value of the laser to 1000)
3. Turn off the power of the machine and check whether the bottom lens of the laser module is dirty. Please use a cotton swab to wipe the laser lens to make sure the lens is clean, and then perform the engraving test again.
4. Properly reduce the speed. The speed of the plank is about 3000mm/min. Note that it is not mm/s. (lower speed possible)
5. Refer to the instruction manual to readjust the distance between the laser head and the object to be engraved. If the focus is not accurate, it will also result in failure to engrave. You can try different distances to see if there is a change.
6. If none of the above steps can solve the problem. Please project the laser on a farther wall in a place where there are no other people, take a picture and send it to us. (wear glasses and be careful)

Check whether the screen cable is loose, and re-tighten it; Remove the screen from the machine casing and put it on an insulating object to see if it is better. If it is better, add insulating tape between the screen and the machine casing when putting the screen back into the machine; if it still does not improve, it means that there is something wrong with the screen. Replace the screen.

Check whether the power supply voltage of the printer complies with the local rated voltage;
If the switch light is on, but the power light is not on, it may be that the wires on the power supply are connected incorrectly or the ship type switch is connected incorrectly, resulting in no power supply. You need to check whether the wires are connected correctly;
When both the switch light and the power light are on, but the main board light is not on, it may be that the main board cannot be used due to the short circuit of the broken material detection. You only need to re-edit the wiring sequence to solve it.

Check whether the card can be used normally on the computer. If the SD card can be used normally on the computer, save the file to the computer first, then format the card, and test it on the machine after formatting; if it cannot be recognized, It proves that there is a problem with the SD card and needs to be replaced; The file code is wrong, the code needs to be renamed;

Check whether the motor is operating normally, if it stops rotating, try to restart the machine;

Try to troubleshoot the problem from the following points: Motor drive current is too large, re-adjust the appropriate drive current; The synchronous wheel of the motor is not fixed – retighten the synchronous wheel; The hardware position of the machine, such as the optical shaft, the slider, and the lead screw, is stuck – manually adjust it until it is smooth after oiling; The belt on the X Y axis is too loose – readjust the tension of the belt;
