Motor Z not responding

I received a 3018 Pro on my birthday, ie yesterday.
I mounted the cnc and did what was written install the CH340 driver and installed Candle. I plugged it in turned on and reported the port in the software. The software confirmed the connection to me but no motor moves when I run it. I looked for a solution but nothing worked. So I decided to do my engraving in Easel. I plugged in the machine, set up the machine and tried to move the axes. The x and Y work very well but when I test the Z: nothing … even the other axes did not move … I have to restart my CNC for them to work again. So in conclusion I cannot use the Z axis.
Can anyone help me?

home your machine first?
