Laser Hatch

A laser hatch fills a closed region with parallel lines at a chosen angle. Lines are clipped to the boundary and to any internal islands. The fill can run as multiple passes, with the laser focus dropping by a fixed Z step between passes.

Hatch direction and overscan

The Hatch Angle sets the direction of the parallel lines: 0 degrees runs horizontally, 90 degrees runs vertically. Cross-hatching is two laser hatch operations at different angles on the same region.

Overscan Distance extends each line a small distance past the boundary. With CO2 and diode lasers that take time to reach steady power after starting a stroke, overscan keeps the actual fill region from being under-burned at the edges. Default is zero.

Settings

SettingDescription
Hatch AngleDirection of the parallel lines, in degrees.
PowerLaser power, 0-255 (machine-dependent scale).
Number of PassesHow many times to repeat the fill.
Z StepVertical drop between passes, in mm.
Overscan DistanceExtra travel past the boundary at each line end, in mm.

Feed rate comes from the assigned tool preset. Line spacing comes from the laser tool's defined width on the preset.

Tool requirement

A laser tool. The tool's effective width determines the line spacing of the fill, so wider beams produce coarser hatching.

When to use

  • Filling shapes with a hatched or shaded look
  • Cross-hatching by stacking two hatch operations at different angles
  • Area marking, texture, and infill on engravable material
  • Burning off a coating or paint within a defined region
