The dreaded..........."Backlash"

[Robin Hewitt]

Backlash is how far you can turn the handle when you shift direction before the slide moves.

Backlash happens in the screw mounts and in the nut.

The lower the backlash in a nut the more expensive it becomes.

Zero backlash is achieved by springing two nuts together, you get zero backlash up to the preload.

You can compensate for backlash in the software but only if your slides are tight, if the tool pressure can move the slide...
