new printer gantry over run. I'm lost

[rainsdrops]

I recently finished building a twoup kit.
I haven't been able to print anything
I'm using the repetier host, to slice &amp; generate code.<br><br>I drew a solid cube, 2" x 2" x 2" (50.8 x 50.8 x50.8 MM).
I've place the cube in several gantry locations in Repetier.;( Middle, all corners, and various areas in between.)
Each time i select print, the extruder head, moves towards, and over RUNS X & Y axis

I've tried make bed dimensions smaller. adjusting the initial distance from bed.
I'm lost

repetier / slicer was generating a homing command, in the post file. I edited slicer, so that a homing command, was not posted.
