Hi Alex
Thanks for getting back. My understanding after having experimented with Home Off. is that once you input a Home Off. value in Homing Limits, and click Part Zero X so that now the axis and part DROs have the same Home Off value (Auto Zero set), then you do not need to phyically take a skim cut of the dia of the part that is in the chuck and input into the Part X DRO. All you need to do is Part Zero the Z axis on the lathe and you are set. So, the main advantage of Home Off is removing the need for this step. Correct?
As for the tool tables: my understanding is that since all offsets are set relative to the master tool, once the master with Home off values has been referenced to Part X zero as I wrote above, all other tools should be correctly positioned. Correct?
Thanks for the help.
