I uploaded a Marlin to my Ender that I "thought" was on it already after making 2 changes, and it trashed my graphics on the Ender. I just gave up for the day.

Well, I certainly boned my Ender. Apparently the screen graphics on the reprap smart graphics controller are not happy. I have not uploaded firmware to this since I upgraded the controller board. I'm sort of floundering here.

Right then - I have the solution. It's apparently a known issue, but I never had the problem the last time I uploaded a sketch. A little searching resolved the issue. First thread I saw to fix it advised editing the "ultralcd_st7920_u8glib_rrd.h" file to add (or change) the three lines below:
And that did not work. Other suggested that this only worked if you put it in the configuration.h file so I tried that. I added the above 3 lines beneath the entry:
"#define REPRAP_DISCOUNT_FULL_GRAPHIC_SMART_CONTROLLER"

The board is being weird about that above post. I may make a designated post about the issue and delete this one for clarity.

When I had my Ender, I found the easiest Marlin version to work with was KAY3D Cheetah. If nothing else, maybe it could offer you some insight into vanilla Marlin. 3dprint.boards.net/thread/12/cheetah-5 |

In the config.h file, add the 3 below lines
#define REPRAP_DISCOUNT_FULL_GRAPHIC_SMART_CONTROLLER
#define ST7920_DELAY_1 DELAY_NS(0)
#define ST7920_DELAY_2 DELAY_NS(250)
#define ST7920_DELAY_3 DELAY_NS(250)
