Wiring SD card reader to MKS 1.4
September 10, 2018 07:55AM
Upgraded my CR-10 to an MKS gen1.4 for more pins and program memory. Everything's working fine besides the fact there is no SD card reader as I wanted to save the original screen. I bought this one and wired it up to accordingly to the diagram I linked below. I supplied 5 volts from the aux3 pins and verified the reader was getting power with a multimeter. Wouldnt read anything. Plugged in the integrated SD card reader on another screen, gave it 5 volts, and it worked fine.

Anything I'm doing wrong? It's such a simple board so I'm really skeptical that it's a DOA.

The SD card is enabled in the firmware using a command like this.

#define SDSUPPORT

Do you know if this was done.

Also the SD card pins might need specifying if no display is specified in the config files ?
