Auto Bed Trimming / Leveling help!! (with pics)

I am having some trouble getting my induction probe to auto bed level.
I have an ord-bot (http://imgur.com/XlZK44I) with the following settings in Simplify 3d (http://imgur.com/3MIuORi). And my marlin config file: (http://paste2.org/y01Nam0X)
When homing the Z goes to the top limit switch, Y to the back limit switch and x to the right limit switch (as seen in photo). The probe sits roughly 45mm to the right and 35mm to the front and when the hot end barely touching the plate the probe triggers. When I do a G29 command after homing, the hot end bottoms out (front right corner). This is due to the prob being off the bed, shouldnt it be centered?. I am getting confused with all the config etc.
Also when i home the machine I have a positive values of z 278.00 (homes tot he top of the machine) and x 295.00 (homes to the right of the machine) where as Y is 0 (homes to the back). This is where I get confused, should homing be a 0,0,0 number or have i got min / max etc mixed up somewhere..

So I need some help getting this all to work so I can enjoy auto bed leveling.

Any help would be greatly appreciated.

Please post your Configuration.h file.

OK, first... Which version of the Marlin firmware is this? This looks like it came from GitHub but only version 1.0.2 from over there works right now. If this isn't 1.0.2 you need to start over with that.

You have Safe Z Homing turned on but you have the

#define Z_PROBE_OFFSET_FROM_EXTRUDER 0 set to zero? Does that really make sense? Usually it is a negative number. Can this number be -.05 ? Induction probes haven't been used a lot and having a tiny bit of negative might be helpful.

And... The Safe Homing position is set by:

#define Z_SAFE_HOMING_X_POINT (X_MAX_LENGTH/2) // X point for Z homing when homing all axis (G28)
#define Z_SAFE_HOMING_Y_POINT (Y_MAX_LENGTH/2) // Y point for Z homing when homing all axis (G28)

But X_MAX_LENGTH and Y_MAX_LENGTH are not defined as far as I can tell. So, it won't safe home to the center of the bed!

Also, it looks like you have the home limit switches set up different on the X and Y axis. Do you really want to home towards Max for X and Min for Y ?
