This RAMPS add-on enables you to print from MicroSD.With RAMPS 1.3 and higher it's easily connected to the RAMPS board.You will be able to print 

without being connected to your PC.



== Features ==
*SPI mode
*Support voltage:4.5 to 5.5V
*Up to 50 MB/sec data transfer rate
*Sits directly on a Arduino
*Also be used with other microcontrollers


==Usage==

'''[[Sometime  you're not sure whether a card is working or not,you must test it.]]'''

Now,let's go.

OK,the card is working.


'''[[RAMPS 1.3 with Sprinter firmware]]'''

These steps will guide you on how to use the SD RAMPS with RAMPS 1.3 and the Sprinter firmware.

Note that you MUST install Diode D1 on the RAMPS board if you want to be able to print without being connected to your PC - see:

2. Download the latest Sprinter firmware from[https://github.com/kliment/Sprinter Sprinter]

Extract the firmware and open it in your Arduino IDE(00-22 ,00-23).

3. Go to the file configuration.h and change the motherboard setting:

define MOTHERBOARD 33

4. Check that SD Card support is enabled:

define SDSUPPORT 1

5. Compile and upload the firmware.

6. Open the Serial Monitor from the Arduino IDE. Make sure the left select list reads newline. Enter the GCode M21 (init SD Card). It should return ok.
