Ok few things in your xml, you have limits and home switches enabled but set to Pin 0, so I presume you dont have any connected. If that is the case just disable them.
I also note you are set in Inch units but your Steps per unit for the motors seem very small, they are 320, I would be expecting at least 10 times that and possibly 100 times.
Your Velocity is also exceptionally high for imperial units.
Maybe you are meant to be set up in metric units?
regarding your PP address, it will likely be the first 4 digits in resources.
