That's a pretty slick technique. I think the technical term is removing the Hysteresis from cross slide. Same effect as tapping on the surface plate to settle a tenths indicator.
I can see the movement of the carriage from rattling the carriage from my readout. I have a readout that reads in microns of diameter. I can get it moving up to six microns by rattling the carriage in my case. This was the first thing I tested when I installed the scale. However I can adjust the position by single microns from the crank easily so I am looking for a method to eliminate the possibility of movement there- I've thought about adding a spring that pulls the carriage against the screw tension but it would be possibly affecting boring operations negatively. Maybe I need to get an anti backlash nut.
Thanks for your viewing and comment. I would suggest that as soon as you arrive at the number you want on the readout, you back the screw off slightly but not enough to take up all the backlash. This relieves any tension on the screw and the carriage will not move for a fine cut. Subsequent super fine cuts can be made like this as long as you relieve the tension each time you advance the carriage. This what I do with my milling machine that has a readout and it works quite well.

@@1973JHE problem is that I want my finish cut to be 0,25mm deep. It can shift the slide if there's no support.
