I have to agree with this. It does depend rather on what sort of work you do. If you are a factory producing runs of hundreds to thousands of parts from identical blanks then being able to home and hit go first thing in the morning is useful, especially if the machine is run by a trained monkey. If you are doing short runs or one-offs, zeroing to the work makes more sense. From what I have seen emc is designed more from the perspective of the factory producing 1000s of parts. > Softlimits are less useful on lathes, Z limits change dependant on where > the tailstock is, and whether you are using collets or a chuck. > Now if you could quickly jog to a position and say 'this is my Z soft limit position' then soft limits could indeed be very useful on a lathe. A couple of times I have hit the tail stock while jogging Z. Luckily I didn't move the tail stock far enough to release the work but there is a potential there for a serious accident. I think I will fit a limit switch on the tailstock to try to avoid this in the future.
