The tool leaves the Home position, moves to the Safe Z level, then above and across the material's surface until it reaches the point of entry. This movement is known as a Rapid move, and is indicated by a blue line.
The tool cuts into the material's surface at its Plunge rate. A cyan line marks plunge moves.
When the cutting is complete, the tool retracts from the material to the Safe Z level, and then moves above and across its surface until it returns the Home position. This is another Rapid move marked by a blue line.
If a toolpath includes several Rapid and Plunge moves, the lines in the 3D view representing the tool's movement can become obscured. For this reason, you may want to hide them from view.
Rapid and Plunge moves are drawn in a toolpath simulation by default, but can be hidden using one of the following methods:
