I am having trouble with my prusa i3 rev B. I had followed the instructions on the google drive as instructed and all appears to be physically correct. I was able to load the Arduino program without the RAMPS board attached, power light and rx and tx light up, but I do not get any LED to light up from either board when they are attached and I seem to lose connection with the Arduino board.
I am using the Repetier program to run the 3D printer and cannot seem to get the software to run the hardware.
Any suggestions would be greatly appreciated.
