I never do that, it is for LinuxCNC to know what the machine limits of travel are. I use the Axis touchoff button to set coords. There are what I consider to be quirks in the way LinuxCNC treats the workpiece coord systems, but if you use touchoff instead of G92 L2 Px then Axis handles these quirks. Otherwise, when a program is aborted or ends, the G92 L2 Px offsets are cleared. Axis resets these offsets as soon as LinuxCNC clears them, so you are unaware of this behavior. To my thinking, when I set a workpiece offset, I expect it to STAY set until I change it explicitly. There is a command that restores the cleared offsets, G92.3. You should read the user manual, around page 86 in : http://linuxcnc.org/docs/LinuxCNC_User_Manual.pdf
