sorry in advance it's probably been said a thousand times.

i have my axis set up and working, just dialing in the configuration in UCCNC.

my question is how accurate is accurate?

if i ask the mill to move 30mm (units set as mm) it moves 29.9992

is that close enough? i would like it to move 30mm if i ask it to. am i expecting to much?

thanks neil


ps. sorry if posted in the wrong section
