Varible Run - What is it?
Variable run is used when an object has tight curves. The fixed run has a set length and does not always follow the exact outline because the stitch length is too long to get around a tight curve (Figure 1).
If you turn on the variable run option then Wilcom will automatically drop in shorter stitches when required, varying from the minimum to maximum length set in the properties (Figure 2). This produces stitches that follow the curve more closely. The maximum stitch length can be your choice depending on what you are trying to achieve, however the minimum stitch length should be at least 1mm. A 1mm stitch length produces a stitch that is longer that the width of the needle. (A 75/11 needle is .75mm in diameter.) Keeping the minimum stitch set to 1mm or above will cut down on thread breaks.
The chord gap is the distance between the outline and the actual stitches. The smaller the chord gap value, the closer the stitches will follow the curves.
When digitizing with the right mouse for curves you have no control over the needle penetrations, using variable run will automatically control and create shorter stitches when needed. If you wish to do this manually then you can use the left mouse and place your nodes closer together on the curve, this will drop the needle in the position you specify.

Fixed Run Length Stitches too long to follow tight curve. Variable Run Using default values drops in shorter stitches when required.
