It works fine with hot keys but doesn't move at all or even try when it loads g-code

Make sure the extruder axis is set correctly in the slicing software generating your g-code.

If you're using Slic3r. You will have to set it up correctly. These threads helped me a lot:

There's even more setup information in the Slic3r subforum.

Yes, the skeinforge profiles were for a constant velocity extruder, slic3r is yhe best way to go!

Assuming your extruder is calibrated correctly.
Getting the base layer to stick is a combination of the base layer height, the base layer temperature and the surface your printing on.
If you're using PLA, and don't have a heated bed use blue painters tape as a surface, I've never had good luck with ABS on any surface without a heated bed.
If the first layer is too low, the plastic will curl up off the bed.
If it's too high it will look very round on the bed.
It should look slightly squashed.
If it still won't stick try printing the first layer a little hotter.
