Robo R1+ noob here. Just got the reprapdiscount red board. Now I'm trying to install it. A couple of problems... 1. There is no marking on the connectors on the board nor the adapter that attaches to the ramps card. I've looked at a ton of photos, videos & msg threads and nobody ever brings this up. Can someone tell me how to connect these correctly before I try to fire this thing up? 2. It seems I may have to make a change to the firmware: Is this the printer firmware or LCD controller firmware? Where do I find the firmware files to alter & upload? My printer is new and has the latest firmware installed from the factory. I am skilled with Arduino and the IDE so I can do the update with no problem if needed. I have the red Reprapdiscount Full Graphic Smart Controller with the LCD contrast adjustment on the far left bottom. I would certainly appreciate any assistance so I can get this thing back together and printing again.
