You need to find out where the 'slop' is. Work your way through every component-to-component connection until you find what's loose.
Start with the motor-to-encoder connection, then go on to the motor shaft-to-sheave, the sheave-to-belt, the belt-to-sheave, the sheave-to-ballscrew, the ballscrew-to-ballnut, the ballnut-to-carrier, the carrier-to-table/saddle/bolster. If you have a direct-mount motor, check the coupling, etc.
You also have to check the thrust bearings. They trap the ballscrew to the fixed part of the machine so that the ballnut can move the axis. The pre-load on the bearings prevents the screw from moving relative to the saddle/base/column.
You should be able to get the backlash down to a few tenths.
I usually find the bearings are the problem but you have to check the rest to be sure.
Good luck with your search.
