Retract/Cutoff/Stop stop length — This is the distance from the normal contour end position to the inserted stop or end position.
Stop Code — For stop operations you can choose from:
- M00 is program stop. This stop is always performed.
- M01 is optional program stop. There is a setting on the machine tool to observe or skip these stops.
Retract/Cutoff retract length — This is the distance that the wire retracts from the part at the end of an operation.
Use on both ends of skim passes — Enable this option to apply the Retract length to both ends of skim passes. (The wire does not return to the start point at one end.)
Retract/Cutoff overlap — This is the distance by which the normal contour end position is overcut.
Contour Overlap — This is used only by the Contour operation. It is the amount by which the Contour operation overlaps.
2 axis Pocket/Zigzag total stock
This parameter sets the amount of material removed from the contour when using the Offset Method of Offset Toolpath. When the value is 0, only one cutting pass is made.

Stepover — This is the default stepover for Pocketing or Zigzag operations. Specify this default attribute as a percentage of the wire diameter.
2 axis Pocket/Zigzag finish allowance — This is the amount of material left after a Zigzag pass. Even if a Cleanup Pass is used, the finish allowance still remains.
2 axis Zigzag cut angle — This sets the cutting angle for a Zigzag operation.
The angle is defined from the X-positive axis of the current UCS. Enter the angle in degrees.
Cleanup Pass — Enable this option to create a finishing cut at the end of a Zigzag operation.
The contour is cut with a contour parallel finishing path to remove any rough edges left by the stepover between passes.

4 axis/Rapid toolpath linear approx — In 4-axis wire EDM, all arcs are converted into small line segments. This attribute controls how finely arcs are refined into lines. The smaller the number, the more points arcs are broken down into.
Keep wire vertical at retract — This keeps the wire vertical after Retract and Cutoff operations for 4-axis features.
The following example shows the end of a Retract operation with Keep wire vertical at retract selected:
This is the same example with Keep wire vertical at retract deselected:
