Does it say that the file exceeds the limits? If so, it is because you are misusing/don't understand homing. Sounds like you are using homing for the job that work coordinates are intended for.
Jog your machine to the point that you want to be the 0,0 of your part. Then use the "touch off" button to set X and Y to zero. Then your G code should run.
