Gotta love 3D printers! I was putting my solidoodle with RUMBA back together after using some parts on another printer and I figured I would add the full graphic smart controller that I recently got. It worked fine on my kossel. So I added the U8Glib library, uploaded my firmware and went to work. I noticed it had a min temp error showing on the display before I plugged the thermistor in, as expected so I thought it was working. Well, I put the rest of the printer together, looked at it again and its just a pure blue screen. No beeping at me or anything, and the kill button still works to stop a print, but I'm getting nothing out of the LCD screen or control stick.
I know its plugged in right, but I tried reversing it at the board anyway. I'm stuck. Any idea where to begin troubleshooting this? Thanks.
