Thanks Craig, I truly appreciate your attention.
I understand your explanation .... OK.
So, regarding... 1) why in the heck would a "Go to work" button send an axis to MACHINE 0 ?
2) For a lathe, why wouldn't it be X an "Z" instead of X and Y ?
3) never happens.
Actually, regardless of where the Z axis, the Z axis DRO never changes . ? ?
If I load a file , then jog away several inches in X and Z, then hit the button only the z goes to WORK 0.
I must be really missing something here.
Thanks for your attention ... and help.
Kindest regards,
Russ
