Hello Jim,
Perhaps I didn't describe what I meant very well.
I'm not referring to referencing or homing. I am referring to the ZERO button that is beside the DRO's.
On the regular Turn screen, and any other I think, you cannot ZERO the DRO's MACHINE coords with this button.
But on the Silver/Blue screen you can....but cannot zero the PART coords, which you CAN zero on the other screens.
Thanks,
RC
