Hello to everybody and thanks in advance to who will help me!
My name is Luca, I’m italian and I bought an AnetA6 3D printer on AliExpress last 28th March, but I never seen it work!
Here is the complete story:

  1. Once recived the kit I mounted the whole printer, but at the first power ON nothing didn’t work, only a fan turning , no lights on the MainBoard nor in the LCD Display.
  2. The seller sent me a new MainBoard. Once received I mounted it, now the red light turns ON but nothing more. If I press the reset button the red light turns off for a while then it turns ON, the back light of the LCD Display turns ON but nothing happens… The seller told me to try to swap the LCD cables (J3 and LCD) but nothing changed (only the backligth of the LCD was OFF)
  3. The seller sent me a new LCD Dysplay, I mounted it but nothing changes, the behaviour is the same of point 2)
  4. I checked the power supply voltage that is 12.43V (correct)
  5. I dismounted both MainBoard and LCD Display and I connected the on my desk using a 12V Battery, but nothing changes (same behaviour of point 2).
  6. I wrote to Anet3d.com describing my situation but I got no answers…

My questions are:

There is a way to check that the mainboard is working, maybe connecting it to a PC using the USB ?

There is a way to check the LCD Display ?

Thanks

Luca
