Interactive Klartext course · Lesson 4 / 15

Incremental coordinates and a first slot

Combine an absolute starting point with incremental moves measured from the current tool position.

What you will learn

  • Recognize the difference between absolute and incremental coordinates.
  • Use IX and IY for distances relative to the current position.
  • Keep depth, cutting feed and retract moves explicit.

How it works

An absolute X or Y value targets a coordinate in the active datum system. An incremental IX or IY value adds a signed distance to the current position instead.

Incremental moves are useful for local geometry, but each result depends on the position reached by the previous block. Simulating the sequence makes that dependency visible.
