I have a new Prusa i3v built and sitting on my desk. Uploaded firmware, disconnected it from the computer, plugged in the graphical interface, and plugged the board back into the computer as per instructions. The lcd screen lights up, it beeps, and then it shuts off. It then repeats. It will cycle like this over and over as long as it has power, about twice a second. Anyone have some ideas?
edit for update:
i have the ribbon cables
plugged in correctly, and uploaded the graphical firmware (GLCD). i have a RUMBA.
With the RUMBA, make sure you have your ribbon cables plugged in the right way. They are really short, and are not keyed on the Rumba board.
