Hi, I have this full graphic smart controller:
I can get it to control my CNC, but I can’t get it to read an SD card. I have tried various different cards, all 1 GB or 2 GB, and 1 16 GB SDHC card. I have tried formatting both FAT and FAT 32, and I have tried formatting both with the Windows utility and with SDFormatter. I have also tried wiggling the card and removing/reinserting, but no matter what I do, the display always reads “no SD card.”
I bought everything from here. Any other ideas of what else I could try?
