The red line is the 12V positive pole, the black line is the negative pole, and the yellow line pwm is the positive pole (0-5/12V, 0-20KHZ). If the Pwm of your control board exceeds 5V/12V, it will not be able to control the Pwm adjustment of the laser. Or you can choose to use our control panel. Use a laser with a nozzle to cut wood, etc. It is recommended to use it with an air pump to blow away the smoke. After many times of cutting work, the smoke will pollute the lens and affect the engraving effect. Please use alcohol wipes to clean the lens. In the maximum cutting thickness data we show, the wood is pine board/basswood board. The maximum cutting thickness of the laser is affected by the wood density and material. 40w80w is the collective name of laser manufacturers, it does not mean that the input and output power is 40w80w. The specific parameters are displayed on the details page.
