I bought an engraving laser machine in China in September… (The model is a JSM40U…) I received and tried to connect it… But every time I tried to switch on the machine, my circuit breaker stops. I don’t understand why… The engraving machine works normally with our current intensity (220v 50hz). I tried different sockets in our workshop, but that didn’t change anything. I bought a multimeter to check if the current working properly in the machine, but I do not really know how to use it...
As you see, I am really a beginner in electricity and electronics but I want (and I need) to learn.
So, if you have any idea why the laser machine does not work, a suggestion of what I could do, an advice or a way to proceed to find the default... let me know! It would really help me.
Have a good day!
