Building my first RepRap but I'm Stuck

Hello,
First I have to say that I am so excited about this RepRap project. I have been spending all my extra time working on it.
I'm building my first RepRap but I am stuck. I built a Pursa Mendel. It has a Arduino Mega 2560 R3 Board and Ramps 1.3. Everything is assembled. I have loaded both Marlin and Sprinter filmware on to the printer. I have got ReplicatorG 26 to connect and stay connected but I can't get the motors to do anything. I know that the motors have power running them because when I turn one of the Z axis motors by hand the other one moves. I have tired everything I can think of. Does anyone have any ideas of what might be my problem.

Can you get it to do anything? For example, turn on the hot end, heated bed, or fan. Does the printer respond when you send an M114 or M105? If you can communicate with it, but the motors won't work, check all the connections on the stepper drivers, RAMPS board, etc. for bad connections. Also ensure that the stepper drivers are correctly inserted on the board.

Use M119 to check what the Endstops are reporting. Then check the firmware settings for the endstops. Make sure that the settings and what is being read match and not stopping motors from moving.

That can happen even if there's no power from the board to the motors:

Post re steppers turning

Presumably all the small trimmers by the stepper driver ICs are not turned all the way down?

I tried m119 and I got x_min:h x_max:h y_min:L y_max:H z_min:H z_max:H so what does that mean? I'm trying to figure out how to set up my endstops but i'm not sure.

I check the trimmers and they are not turned off. When ever I send the printer a move command the LED doesn't do anything, shouldn't it blink?

M119 results explained.
Yoour results: x_min:h x_max:h y_min:L y_max:H z_min:H z_max:H

The x_max:H y_max:H and z_max: H is expected. We do not connect endstops in the default builds to the max switches. As a result these swicthed will always report H (Sitch is Open)

A value of 'H' means the circuit is open.(If using normally closed switches NC, then the switch is pressed.)
A value of ''L' means the circuit is closed.(If using normally closed switches NC, then the switch is NOT pressed.)

So the question is did you have the X and Z axis endstops pressed and the Y endstop not pressed?
