from this position. This motion
ensures appropriate
engagement force between the
table's top and base.

Table "disengaged" position

Lift top 3 mm to allow base to
rotate. First mm lift returns to
"neutral" position and re-
engages the clutch; remaining
2 mm provides clearance
between table's top and base,
to allow base to rotate. Set the
machine's reference point
(relative zero) for this axis after
you have performed this lift.
