Zero to bucket

When the excavator starts for the day or moves its tracks to a new location during work, an elevation reference is necessary.

Put the bucket on a known good grade point.
Select the Elevation Control button.
Select Zero to set the elevation reference to zero.
ADDITIONAL INFORMATION:
3D-MC calculates the elevations for the area in range of the excavator to set the bucket to the known reference point (good grade point).
Figure: Control configuration elevation tab
When you move the excavator to a different location, do this again to follow the elevation or slope.
