Rostock Mini - X & Y Not moving during print (video)

Thank you all for you help thus far. My Rostock Mini homes now and I'm very grateful for your help.

My issue now is that my printer is moving to print but the x and y do not work.
- The Pronterface software shows the Gcode is processing.
- The rostock homes
- The head moves to begin the print
- The extruder moves correctly
- The z axis moves correctly after each layer
- The x and y do not move after the initial parking position.

Please watch this video (skip to 2:20 to see the printer start to move) and let me know what you think may be happening.

As always, I've attached the Configuration.h file

Thank you in advance.
