I am using Geeetech LCD2004 with ramps 1.4, mega 2560, and L shaped EXP1/ EXP2 adapter.
I found that by turning cables 180 degrees I was able to make LCD screen work mostly.
Now it will turn on and show main screen. knob works to adjust Fr. Pushing button to access menus will blink the menu for a fraction of a second and then jump back right away to main screen.
Could you please advise about correct Marlin settings pertaining to button?
