Hello, I use Creality falcon2 40 watts. After making a cut, all the lights went out on my machine while I was preparing the next cut. The green light on the adapter is on but there is no power to the machine and laser. What could be my problem? ---

There are two likely problem areas: 1. bad power supply 2. bad controller A bad poer supply is a common scenario. If you have a meter, test that you’re getting the appropriate voltage reading from the supply. I’m not familiar with your machine but these will typically be either 12V or 24V with most newer models being 24V. ---
