my screen problems are basically: 1. couldnt find all of the code niblets the instructions said to enable. 2 screen lights up with no data displayed. 3. printer is not picking up the sd card slot. (sais sdinit fail when connecting in pronterface) have been going back and forth with support for the screen with josh at makergeeks. printing a test cube now and it looks a lot better since uploading sprinter again
