Okay, Now you are just talking stupid. The reason you would bet the
farm that you don't have to bet, is that you don't know what you are
talking about. Manual mills may have upwards of .100" backlash.
Industrial CNC machines (and most hobbiest CNC machines) that use ball
screws have less than .002" backlash on the screws. An even greater
majority of precision metalworking machinery (industrial machine
tools) have less than .0006" of backlash. Most machine tools using
ball screws go so far as to even put two nuts on with a tab between
them to further eliminate backlash to near zero (usually .0002" or
less). When a machine tool get's excesive mechanical backlash, you
would adjust the two ball nuts to remove it, the software compensation
is only there to take care of .0003" or so.
Now drop this discussion and quit demonstrating your ignorance on the
subject mater.
