Hello All,
I decided to build my own 3D printer (Marlin FW, Arduino Mega, Ramps 1.4) and recently purchased a RepRapDiscount Full Graphics Smart Controller to use with it. I have connected it up and uncommented the line of code in Marlin to use it. When I turn on the machine, the LCD screen shows the main landing page (extruder temps and positions). I can press in the button and get to the menu screen, however, once on the menu screen, I cannot scroll through the menu options. Turning the knob takes me back to the main landing/information screen. I assumed that the LCD was potentially faulty and purchased a second one, however, I'm having the same issue.
I have tried:
Multiple cables of differing lengths
Multiple units
Reseating the cable connectors on both the Ramps board and the back of the LCD
After searching both this discussion board and google, I've found a few people with the same issue, however, they never post a solution to the problem. I'm at a loss at this point. Does anyone have any ideas as to how to be able to scroll through the menu options?
