I have Ramps 1.4 board with installed FULL_GRAPHIC_SMART_CONTROLLER
and Marlin firmware. Everything is fine except LCD encoder is not working properly.
I see welcome screen on LCD and info screen, where I can click on encoder and
switch to the menu screen. Here I can not choose anything. Left, right function is not working.
Cursor does not move, I can here only click on encoder and return to the info screen.
First my idea was - encoder has defect. I have installed Repetier-Firmware and
found encoder is working correctly with it ! I have made double check and found, configuration
in Marlin and Repetier is using the same pins for encoder. 31 and 33 for left, right and
35 for the click button. I have gave up, what can be the issue with Marlin.
Any help very appreciated.
P.S. Found the same or very similar issue here [forums.reprap.org]
