It's actually very easy to do this.
It is at the very end of the post, if I'm thinking correctly, all you have to do is comment out the line
writeRetract(X, Y);
This should do what you want.
On my Mach4 post that I use, I use G30. This will move X, Y, and Z to specified machine coordinates specified in the #VARS 5181 -5183. Very handy if you want the X to move to the center of travel and the Y forward.
I can share my post tomorrow if you would like. It is on my work computer and not my laptop here at home.
