Guys, I am having problems setting up a Rambo board on my 3D Printer, this is genuine board I paid lots of money for not a cheapie! System is Windows 10, COM6, Arduino has RAMBO set as board 301, no problems so far.
Every time I try to upload I get the following message
Warning: Board Arduino_1.x.x:rambo:mega2560 doesn't define a 'build.board' preference. Auto-set to: RAMBO_MEGA2560 recipe.preproc.macros pattern is missing
Error compiling for board RAMBo.
So what does this mean and how can I fix it??
