First you need to tell the machine where the stock is, here is how
I do it,
Find the center of the stock using the machine as a dro and a edge
finder(x and y) if it's a square just touch the edge finder or the
tool itself to the lower side of the stock, set the machine software
to zero then move the tool or edge finder to the opposit side of the
stock and touch it there, you now have the distance the machine
moved , take this distance and divide by two and you have the
distance to the center of the stock, move the axis by this amout and
you have the stock center, zero your axis there.do the same for the
other axis.
Now, touch your tool to the stock top that's your Z zero.
You should end up with x,y,z zero at the center(x,y) and top of the
stock.(z zero)
