Stitched Beads 

Each channel may be programmed to deposit beads in a stitched fashion in
order to conserve adhesive.  The beads are broken into a series of shorter
beads.  A percent glue savings and an interval value will need to be
entered.  All the stitched patterns begin and end with a sub-bead.

NOTE:  

Interval (also known as pitch) is the distance from the start of one

bead to the start of the next bead.
