I got my first ever machine. Im converting it to a electromechanical manual mill for now with 3 manual pulse generators and three DQ860MA drivers. Later mach 3 or 4 is calling my name. How much backlash is normal for this cnc ballscrew on x and y. Im seeing about 0.002-0.003" on the built in...

Precision ground ballscrews are only of value in CNC applications with stepper drives or open loop control. Closed loop CNC's with glass/magnetic scales do not need Precision screws for accuracy, but may need it for preload control. Having a DRO on a manual makes "precision" a non-event for leadscrews.
I'm kicking around the idea of putting some ballscrews on my 9x42 Bridgeport, possibly for a future cnc conversion but for now, just to fix some worn nuts with no more adjustment. Mcmaster sells a kit for $700 for both screws with nuts and the yolk. Mcmaster's part number is 29995A74. Pretty cheap for a bolt in deal.
Ball screws are required with a CNC mill. While CNC control is on the servo or stepper holds the screws tight all the time. In manual though the ball screws will move (creep) when not intended. The …

I'm relatively new to machining and a hobbyist. My reasoning behind getting an ACME threaded lead screw instead of another ball screw setup is 1) it costs less, 2) I have never operated a mill with ACME threaded lead screws and 3) at least one of the benefits of having ball screws seems to go away if a DRO is installed.
The mill can be run manually, as a two-axis or three-axis CNC. Manual quill control is with our unique Electronic Handwheel. Note: For most three-axis CNC applications, we highly recommend TRAK Bed Mills. 3-axis retrofits are not available with the RMX at this time. We have transformed thousands of Bridgeport® and similar knee-type milling ...
Regarding Retrofits. The charge for all ball leadscrews is the same, regardless of the overall length. This is because the manufacturer does not give us a price break on the shorter screws (in fact, they wanted more for a 6″ ball screw). All screws come in at 400mm (15.75mm) long, and we cut them to length to fit the individual machine axis.

Every Bridgeport mill rebuild has the option to upgrade to a Precision Ball Screw kit, but only 1 in 6 will purchase the upgrade, according to Bridgeport Machine Rebuilders.

The other factor that comes into play in favor of keeping the ball screws is a Lyman MK-7 Power Feed was included with the mill. It could also be used with ACME screws but it fits on the Y-axis ball screw without an extension.
