limit-homing

Hello,

I was just wondering , when i buy my ox( i will make a lot of cabinet sides etc )

if i place limit switches can i use these also to home my machine so that everytime my X,Y, Z axes ar always in the same spot before a job even if the power goes out or i set the machine of.

then when i start up the machine again i set it to 0 X ,0 Y, 0 Z and its always the same position ,this
is very important to me for drilling cabinet holes they must be every time at the same position.
