Merge Lines

When you import a design that contains overlapping paths, the laser may end up cutting the same line more than once. This wastes time, can cause excessive charring, and may widen the kerf beyond what you intended.

The Merge Lines post-processor detects overlapping and coincident path segments and merges them into a single pass. The laser follows each unique line only once.

When to Use It​

This comes up most often when:

  • You import an SVG or DXF where shapes share edges (for example, a grid pattern or tessellation)
  • You combine multiple workpieces whose outlines overlap
  • Your design software exports duplicate paths

When Not to Use It​

If overlapping cuts are intentional — for example, making multiple passes over the same line to cut through thicker material — leave Merge Lines disabled. In that case, you may want to use the Multi-Pass feature instead, which gives you explicit control over the number of passes.
