Thanks for the update.
I have been playing around with Marlin options like:
- SPI_SPEED
- lcd delays
- font sizes
A big problem is the small memory size of the used 1284p chip, some Marlin options use a lot of memory and you must comment out other options to try different setting most of the time.
From within Repetier-Host or Pronterface I can manage the SD card, adding or deleting files works ok like everything else. You can start a SD card print job from that interface also, when you do not want to print over USB.
So it is definitely not an issue with pin assignment on the Melzi board (which uses the pins_SANGUINOLOLU_11.h file for the configuration).
I suspect the issue has something to do with the rendering of specifically the SD menu itself. It has nothing to do with the amount of files on the card.
As I am no coder, this is somewhat difficult to troubleshoot. All menu magic happens in the ultralcd.cpp file.
Yes, they should share the Marlin firmware.
Can something be gained from the flash hex files when extracted from a stock Ender-2 printer. I did that but they are useless as I first burned a bootloader to the board (which erases the firmware).
Has any of you perhaps have the original .hex files?
