Reducing X and Y Axis Backlash on a RF-30 Mill/Drill

[Okapi]

Thanks Rick,
It answers partially but as you said it can be good as possible, despite I've seen this technology totally out of possibilities especially on Mikron lathes used in production, they have a nut fitted like the nut for the lead screw which is on the horizontal axis and not perpendicular as yours.
Making a lot of work on specific models we have for example a value on Schaublin of 15/100 millimeters on the scale as a standard, this was the sense of my question, as I use those values for others lathes or milling machines.
The best I can make on a normal nut/screw is on the Aciera F series with about 6/100 on the scale before it comes hard to operate, you said it can be less with this technique ?
