On my Okuma lathe they had a g and m code for setting up a 'barrier'
area that the tool was not allow to enter. you could foe instance define
the chuck jaws and then it would error if you tried to machine the jaws.
I never used it but being able to quickly change the soft limits of z would be
very useful. Two buttons in AXIS that when pushed reset the upper and lower
softlimit to the position the tool is at probably would suffice.
