Set Tool Touch Off Pos

When i attempt use the set the tool touch off position button, the X Y and Z remains greyed out and does not change values.  Seems like I'm missing something to make those 3 values become active.

Thanks for any input.

Probe Basic.

Yes all axis was homed.

I jogged down the spindle to tap the touch plate. Tried pressing the button but no response.

Do you have all the subroutines in the sub folder and are you sure you added all the bar file parameters per the docs?
