Hello,
I received my 12864 LCD screen and tried to hook it up to the RAMPS board. I plug in the USB cable to PC and the screen turns on, shows all the info. If i turn on the 12V power supply for ramps the screen dimms a bit.
The strangest part is when i disconect the usb from my pc and the screen just stays lid, no info showing. Plug in back the usb and the screen shows all the info, just a bit dimmed.
So if a want to see the information on the screen, i have to be connected to my pc. Strange..
I made a video showing this behavior.
Can anyone help me to fix this? Whats the point to have a lcd screen with sd card reader if i still need to be connected to a pc. :(
Thank you in advance
