Thank you. I thought that might happen. 
I tested the y axis last week and had it running up to 1500 IPM with that 300lb beam on it! The ball nuts themselves seem to have about .001 - .0015 of backlash which i wasn't at all pleased with but will be ok for my application. In case anyone was wondering the gantry is stiff enough to push on one side and the other side will move with it without binding and even with the ball nuts attached.
