G2S Pro MANY problems!!

[Tools]

Hello,
I bought a G2S over 1 year ago,
I put it together and followed instructions, but it doesn't work.

The auto level function seems useless, it crashes into the floor panel a few times then stops and nothing has changed.
The Repetier printing does not work, it doesn't extrude from neither of the 2 extruders, just zigzags empty and shows as if it did print successful.

Please, it has taken a year of my spare time trying to get this to print just a single item, but no luck so far.

edit:
I'm really sorry it lagged out and made a ton of posts, I've got a ton of gear causing bad local traffic on my end.
I've been reading up on the importance of leveling the floor, it's a perfect same distance all the way around.
I have flashed it with the latest firmware from the forums, fully unedited firmware.
Also for good measure, I have ordered a Geeetech E180 for smaller prints as the G2S pro is obviously too techy for me just yet.

I leveled the bed again to make sure it was perfectly level,
when the printer starts, first thing it does is crash into itself, and then not extrude while failing to print.

Any help??
