Can't get SD card to work

davidgebbett

Hi guys, I'm fairly new to the 3D printer world, so apologies if I miss anything obvious.

I have built a home made reprap printer but I'm having some issues with getting the SD card to initialize or mount. I can print from USB without any problem.

I am using the following;

Arduino Mega 2560

RAMPS 1.4

REPRAP Pro Discount Smart Controller (tried both normal and full graphic variants

Repetier firmware V2 (or what ever the latest version is)

Windows 7, Arduino V1.0.6 to compile, Repetier Host

I have the SDDetect set to -1 and with that I go through the menu on the screen I have an option to mount an SD card but it just resets and nothing happens. If I change the SDDetect to 49 when the SD is plugged in all the printer does is continuously restarts.

Any help would be much appreciated.

Thanks in advance!

Could you test with watchdog disabled. I guess something is taking too long and watchdog triggers reset. Not that it should happen.
