A Prob
You have modify the sdcarddetect. for the Ramps
1 you added SDCARDDETECTINVERTED
2 and added the Pin31 for the SDCARDDETECT
3 and make the Pin 33 for the Beeper

The in old Version works SDRamps whisout you inverted SDCARDDETECT and NOT an SDCARDDETECT
Many elektronik people make a little Wire on the SDRamps and you have an real SDCarddetecd on the SDRamps, you dont need not inverted the Signal
The best way is ask in the Firmware HAVE you have a little Wire on the SDRamps or not, whe you have a Wire NOT invertet the Signal, you have not a Wire the inverted
An the Pin for the SDRAMPS Carddetect is Pin 49 !!, not 31

This ist not the best way
1The best way is NOT INVERTED the SDCARDDETECT !
2 Pin 49 for the SDCARDDETECT !!
3 and make the Pin 59 for the Beeper

Only you must make an little Wire Bridge only of the SDRamps from the Cardslot to an pad of teh SDRamps and the Carddetect works very well, when plug the Card inside or outside the Cardslot and you see on the LCD

Thanks
