...
Used with linear entry or exit, defines length in mm of entry or exit motion. Negative values are not permitted.
...
Extend / shorten path
Undertravel or Overtravel. Use a negative value for undertravel, to shorten the length of the path by some distance. Enter a positive value
Leave at zero to keep original path with no shortening or extending.A positive value will extend the base toolpath by adding a line tangent to the path, at the intersection of the entry / exit. The effect would be to move the entry or exit past the intersection point, creating an overlap.
...
A negative value will move the entry / exit back from the intersection point, leaving undertravel or a gap in the base toolpath.
...
Note that on curved toolpaths, the extension follows a tangent line, it does not follow contour of the toolpath.
...
Normalize direction
When enabled, the vector of approach will be perpendicular to the healed surface geometry, at the start of the entry. This will ensure that the pierce occurs with the torch perpendicular to the workpiece. After piercing, the vector gradually transitions to the cut path vector, as defined with Fanning distance.
