My Kossel XL was running well until it suddenly stopped reading my SD card correctly. When I plug in an SD card the screen goes blank and occasionally flashes, a green light on the main board comes on and off. It looks like it's trying to over and over again. Not really sure what part to look at to fix this, any suggestions about what might be wrong or what to fix would be welcome.
It's a "RepRapDiscount Smart Controller" I've tried:
Reuploading the firmware,
Cleaning SD Card contacts,
Blowing in the SD card slot,
Formatting SD cards,
Using different SD cards,
Checked the ribbon cable pins were not bent,
The printer is about 3 years old and sat unused for about a year before being used for the last few weeks then suddenly having this problem. Occasionally lifting up or playing with the lcd controller will make it briefly flash and then display "Card Removed." Oddly when the SD card is in and the printer is plugged into my PC it seems to work, but only occasionally will it actually start a program.
