The problem seems to be that since 'tools' does not list Arduino RAMBO V 1.4 the compiler keeps trying to use Arduino Mega 2560 (Board 80) instead of Board 301 even after I have put in 301. and it still gives an error message 'Missing binary operator before token '301' and exit status 1. I can not use my 3D printer until I get this problem solved and I do not know how to fix it myself.
