    So i have installed a Full graphic LCD into my 2nd printer, however it thinks the SD Card is inserted when there is no SD card and that there is no SD card when I insert one (Formated to FAT32) any ideas on what i need to change? i'm guessing two pins need to be swapped in firmware but i don't know which ones

    Someone with one can comment, but I do believe the full graphic display requires a switch to be set in firmware (then recompile and reload).

    Well I have two printers with two lcds. One of them is fine just this one is having this strange issue. I double checked the firmware and reuploaded to both printers to check it and still same problem... I've found a work around by taking the sd card holder off the LCD and soldering the detect pin and the little metal arm together. It seems to have worked however unconfirmed if its a defect or by design with this particular model. (Amazon sainsmart LCD full graphic controller.)
