1 Please check if there are incorrect wiring on the main board. Check if there is a wire drop from the laser head connector.
2 Please send me a picture of the window mirror. Please clean the window mirror on the laser module with 95% alcohol and a dust-proof cloth. You can refer to this video to clean it.
3 Please send me a picture showing the output parameter of the power adapter(on the back side) for analysis. Are you able to turn on the laser by the touch screen?
4 You can download the attached 1010.nc file to check the problem. It can cut a small square on a 2mm or 3mm basswood board(The accessory bag includes a 2mm basswood board). Please copy the file to the SD card and use it to check the output power of the laser head. If possible, please send me a video showing the focal length you set, the working condition of the machine, and the test result. Once we can confirm the situation, we will provide you a solution to solve this problem.(Please do not use lightburn or laserGRBL software. You must use the attached 1010.nc file via the touch screen to check this problem. Because if there is a problem with the software settings, it will cause the laser to output the wrong optical power.)
5 There is a way to visually check whether the diode in the laser is damaged. Please set the laser output value to 100% and then shine it on a wall 3 to 4 meters away. A 10W laser has two diodes. If one of the diodes is broken, you can see the abnormality in the distant light spots. The picture below takes a 20W laser as an example. You can see that the light spot on the far right looks different from the other light spots.
If you think this testing method is too dangerous, you don't need to test it.
6 Please ask the customer do one more test. Please remove the window mirror and cut the 1010.nc file to check the problem again. The window mirror is used to protect the focus mirror inside the laser head from debris and smoke/oil. Since the 1010.nc file cut a small piece of wood, the small amount of smoke will not affect the focusing mirror. If the cutting edge is small and clear, I think the laser head is fine, the problem is with broken window mirror. But we don't recommend customers use the laser head without a window mirror. We are doing this this time just to check the condition of the laser head.
