[ddoiron]

Hi All,

Just bought this :

Nice printer, I plug it in for the first time and nothing happens. ...
I plug the USB into the PC and the LCD comes on, but AUTO HOME does nothing.

I try moving axes manually through LCD Menu, nothing.

I load a model into CURA, send the print, the printer goes into "Bed Heating" mode but nothing happens.

It's really like there is power to LCD screen but nothing else.
Fans arent on, the motors have not made a sound, ever.

I have double checked my wiring, it's all too simple to screw up.

This is my first 3dPrinter, I dont know how I am supposed to troubleshoot this.
