Hi,
I am building my first 3D Printer and am having issues with my electronics. So I received a replacement RAMPS and Mega today and installed them into the printer. Unfortunately I encountered the same problems as before.
Firstly with USB only:
The LCD turned on and displayed the info screen as normal. I could connect the printer to pronterface also.
Secondly with USB and wall power:
System turned on however my laptop was shutdown hard. (USB over current?)
Thirdly with only wall power:
The LCD display no longer displayed the info screen but instead displayed all pixels switched on. All fans appeared to be working also. When attempting to reconnect the USB the laptop shutdown instantly again.
I have checked all my wiring and the input voltages are 12.3V on both lines going into the RAMPS 1.4
Thank you for any help or ideas! Im happy to answer any further questions about this issue also.
