Elegoo Phecda The digital display of my laser machine works, but the laser does not move left and right.

While using my laser machine, suddenly the laser head and its movement (x and y) axis stop working completely. My machine’s touch screen works but does not engrave. It does not move even when you turn left and right on the working digital panel. Wifi doesn’t work. I updated the version and software of my device and my problem still persists. What is the solution to this problem? I do not do any work that would damage my laser machine and I use my machine very little.

The machine isn’t grbl and Ruida… it can only be one…

What is the bug?

Is the rotary attached? Which kind?

Check your power supply is connected and it is providing the correct voltage.

The screen and controller receive power from the USB connector, so even if the screen is lit that does not mean the steppers and laser are getting power.

That would cause the machine to not move even though the unit appears powered on.
