How to Use
Upload G-Code or DXF
Upload a G-Code (.gcode, .nc) or DXF file.
View toolpath
See the toolpath rendered as a 2D diagram with rapid moves (red) and cutting moves (blue).
Inspect and verify
Check path order, extents, and total travel distance before running the job.
Visualise Your CNC Toolpath Before Machining
Running an unknown G-Code file on a CNC machine without verification is risky. This tool renders your G-Code or DXF-derived toolpath as a 2D diagram, clearly distinguishing rapid moves (in red) from cutting moves (in blue), so you can verify the path is correct before committing material and machine time.
Real-World Examples & Use Cases
Pre-Run Verification
Preview a G-Code file to catch obvious errors (wrong extents, missing cuts) before wasting material on the machine.
