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.

SVG Closed Path Checker
Check whether all paths in an SVG file are closed. Closed paths are required for laser cutting and CNC routing to produce complete cuts.
SVG Open Path Detector
Detect and list all open paths in an SVG file. Shows which paths are open, their endpoint coordinates, and how far apart the endpoints are.
CNC File Validator
Validate G-Code and DXF files for CNC machines. Checks syntax, feeds, speeds, and extents. Identifies potentially dangerous commands before running.
