Janome JR3000 Series Operation Manual page 53

The robot defines how many times it spirals around by splitting up the outer circumference diameter by
[The Number of Pitches].
Outer Circumference Diameter ÷ (Pitch Count + 0.5) = d
If [Line Dispensing] is set to [Circumference] or [Without], the robot dispenses along the circumference
before drawing the spiral.
 Hollow Spiral Start Point – Circumference of Spiral Area 1 – Circumference of Spiral Area 2
The robot spirals from the Hollow
Spiral Start Point toward the center
at the specified [Line Speed], and
does so by executing
dispensing on a horizontal plane at
the Hollow Spiral Start Point.
The robot draws a spiral in the order
of Hollow Spiral
Circumference of Spiral Area 1, and
Circumference of Spiral Area 2. The
spiral is drawn counterclockwise in
the example to the right.
The robot defines how many times it
spirals around by splitting up the
outer circumference diameter by
[The Number of Pitches].
However, line dispensing ends at the position where the robot exceeds the specified [Filling Width].
