Common Laser Cutting File Problems

Even well-designed SVG or DXF files can contain issues that cause problems on a laser cutter. The most common are:

Open paths: Lines that do not form closed loops, resulting in incomplete cuts.
Duplicate lines: Overlapping paths that cause double-cutting and burning.
Tiny gaps: Near-zero gaps between path endpoints that look closed on screen but cause the laser to treat them as open.
Self-intersecting paths: Paths that cross themselves, causing unpredictable cut behaviour.

Real-World Examples & Use Cases

Pre-Production QC

Validate a customer-supplied SVG before sending it to the laser cutter to avoid material waste.

Frequently Asked Questions

What is an open path in laser cutting?▼

An open path is a line that does not form a closed loop. Laser cutters need closed paths to make complete cuts. Open paths result in incomplete cuts.

What are duplicate lines?▼

Duplicate lines are two lines that overlap exactly. On a laser cutter, this means the laser passes over the same line twice, potentially causing burning or over-cutting.
