Sewing Machine Speed Control (ESD)
This control fits in place of the foot control in the wedge and
solves the issue of having a "sensitive" foot control. This makes the
initial setup of the PC Quilter a breeze!
They are available for short-arm sewing machines and
mid-arm sewing machines from Quilting Technologies.
The foot control wedge simply turns the ESD on or off, and you
control stitch length by selecting it from the dial on it.
