Oops, typo.. 0.04mm, that's what it seems... when turning the knob I can feel when lead screw engages inside the nut.

That's still pretty good, given that wherever you've got mechanical couplings it will be almost impossible to completely eliminate backlash/play.

Yes, I am happy with this, especially when comparing with original situation, when there was a hole in aluminium and steel shaft turning inside..

Actually, cross slide is sort of better (almost no backlash but tighter), this is due to the way nut is attached to the slide (with screw), so when tightened, nut is also rotated a bit (as allowed by screw.. which is then hold tight),

Caliper ready for installation...
Now I need to drill/tap couple of M3 threads on the cross slide to fix it in place.

Done...
Also, yesterday I received measuring strip (it is 600mm long PCB with capacitive encoder pattern), it works with Chinese caliper reading head.
I plan to mount it under the apron for X-axis.
