Ok that is what I was thinking.  thank you very much. 
How do I use the SD card function on my LCD.  I would like to be able the printer with it not hooked to my computer.
I have a brand new SD card never used it yet

I was afraid you where going to ask this next. Now we get sticky as the current version of Adruino will not compile properly when you enable the LCD. You will need to get an older version of Arduino from their website first. Unless you have an older vesion?

You really need version 1.0.5. Just get and stick with that version for printer issues.

Once you get that version, open your firmware in it, and go down to around line 1189 in configuration.h tab. These are LCD features.

Find the the following line,

#define FEATURE_CONTROLLER 0

And change the 0 to the one that that most comes closest to yours in this list.

2 = Smartcontroller from reprapdiscount on a RAMPS or RUMBA board
3 = Adafruit RGB controller
4 = Foltyn 3DMaster with display attached
5 = ViKi LCD - Check pin configuration in ui.h for feature controller 5!!! sd card disabled by default!
6 = ReprapWorld Keypad / LCD, predefined pins for Megatronics v2.0 and RAMPS 1.4. Please check if you have used the defined pin layout in ui.h.
7 = RADDS Extension Port
8 = PiBot Display/Controller extension with 20x4 character display
9 = PiBot Display/Controller extension with 16x2 character display
10 = Gadgets3D shield on RAMPS 1.4, see http://reprap.org/wiki/RAMPS_1.3/1.4_GA … with_Panel
11 = RepRapDiscount Full Graphic Smart Controller
12 = FELIXPrinters Controller
13 = SeeMeCNC Display on Rambo (ORION)
14 = OpenHardware.co.za LCD2004 V2014
15 = Sanguinololu + Panelolu2

I am going to guess 2 would be your first choice.

Then look for the following line,

#define UI_LANGUAGE 1

Change 1 to the language of your choice from the following list.

0 = English
1 = German
2 = Dutch
3 = Brazilian portuguese
4 = Italian
5 = Spanish
6 = Swedish
7 = French
8 = Czech

There are a few other settings in this section you might like to toy with.

#define UI_PRINTER_NAME "Ordbot"
#define UI_PRINTER_COMPANY "RepRapDiscount"

Will show the information inside "" on a splash screen as your printer boots.

Once you enable the LCD the SDcard reader built into the LCD will work. Just run and STL file through your slicer and then rather than printing it, you will export it the SDcard which you will need an SDcard reader on your PC as well to do so. The PC will not see the SDcard through the machine. Well it might if you use Repetier Host and firmware. I honestly have not tried since my laptop has a built in reader and I have always just used it.

How do you home z axis?  I hit home but it goes till it hit the endstop at the glass bed. Is that correct?

Home is the endstop. You have to adjust the position of the switch so the nozzle just almost touches the bed when the endstop gets triggered. Then you use the levelers on the bed to dial all four corners and middle in so you can just feel a piece of paper slightly drag between the bed and nozzle.

If the switch cannot be adjusted then you have to use a positive or negative value in the RH EEPROM manager under Z offset.

If you can, use a non-metallic(ceramic) screwdriver...if you don't have one, a standard jeweler's screwdriver will do, but you need to be VERY CAREFUL to let the screwdriver tip touch nothing else but the trimpot dial or you will fry the stepper chip.

Hi I am unplugging at the ramps board. they turn fine and run fine if both are not plugged in the board at the same time.
How should the motors be wired and plugged? I am new to building printers so I dont know thanks.  The motors each have their own plug that is plugged in the ramps board

I remember when I set up my twin Z motors for the first time I had awful performance when I plugged them in to the 2 separate pin sets on the board...I ended up wiring both motors to one plug and pin set and it worked wonders.  I think I had to adjust the vref up a bit, but they've been smooth ever since.

I followed the wiring diagram at the following site...just scroll down a bit:

http://reprap.org/wiki/Prusa_i3_Rework_ … and_wiring

One of my Z motors will freeze when running both z motors at the same time. So I disconnect both motors and they both work fine when running just one at a time. But when I run both of them the motor locks up and after I unplug it the motor is very hard to turn by hand untill I give it a minute to rest and then its all good again. Not sure whats up with that?

Are you unplugging the motors at the motor or at the Ramps?  If a motor is unplugged and difficult to turn, usually that means that a coil pair (2 of the wires for a common coil) is shorted.  Double-check all of the wiring harnesses.

Also, are the two Z-motors connected to the Ramps board individually or wired together in one plug connector?
