Hey Folkes...
Having an issue with (it appears to be) my RAMPS 1.4 board. I have the Ramps and the Arduino Mega connected to my RepRap printer. I connect the USB to my computer and the Ramps boots showing the Marlin main menu. All seems to be working well with it.
I connect my 12V supply to the RAMPS board and disconnect the computer and nothing happens. Black screen. The power supply is generating 12 V. I have verified that the 12V is making it to the Board. The Power cables are connected correctly to the RAMPS board. Yet, no output.
Any ideas on what I can do to test/fix this?
Thanks
Don
