Relative programming (G91)

Even if next block after delete distance to go is defined relative by G91, the end position of the next block is not recalculated relatively to the stop position at the interrupt. The end of the next block is calculated as if no interrupt had taken place.

A “Delete distance to go” does not result in an offset of the further relative programmed contour.

Delete distance to go with active relative programming (G91)

There is no contour offset if the next block (N20) is programmed relative (G91).
