Cannot print from SD card

[Roxy]

I believe one cable is for the LCD and the other cable is for the SD Memory card. I kind of doubt it is a cabling issue, but given the two functions are on separate cables, it is worth checking. Also, doesn't the Rumba have an SD Memory card slot on the board? If so, you should focus on getting that to work first because they will share a lot of signals. If you can get it working on the Rumba, you have a better chance of getting it to work on the LCD Panel.

Cables are correctly connected, and the Rumba board does not have an on-board SD Memory Card slot. I will keep tooling around with this in my free time but since I use octopi it's not a massive deal. It would be good to get it working in case my usb port died one day though.
