If the ramps is onboard the Arduino do I need to have the power to the ramps hooked up or will it still get power thru the USP.
I just flashed a Mega board yesterday using only the USB port to power it. I had to take the RAMPS board off in order to do that. I think the RAMPS was eating too much power for the USB but I'm not sure if that is really true. I do know I could not flash the firmware without removing the RAMPS board.
