I am trying to install a new board as the old one faded away last week. However, I am getting a premature end of compiling, every time, with several different error messages. I have tried both old and new Robo firmware and at least 5 different versions of Arduino working backwards in releases. I have a Robo R1 beta that has been doing hard work for over 2 years and would really like to get up and running again. Any Arduino/Marlin volunteers out there?
