SD init fail using RepRapDiscount Full Graphic Smart Controller in Repetier 0.91/0.92
I have a RepRapDiscount Full Graphic Smart Controller that I am running on a RAMPS 1.4 board. The display and the menu work fine until I connect an SD card. Then the entire thing slows down and in Repetier Host I get "SD card inserted" "SD init failed" repeating every second or so.
I am running FW 0.91 from the web configuration tool. I have tried a variety of settings in the firmware as well as 3 different SD cards. Searching online I saw some reports that something may have changed in the timing between version 0.83 and 0.91 that might cause problems? I have never run anything prior to 0.91, so I don't know for sure that that is the case. I tried 0.92 and had the same problem. I have sd support enabled and set the sd detect pin to pin 49. If anyone has run into this or knows how what the problem is, I would be very appreciative.
