CNC File Validator

Validate G-Code and DXF files for CNC machines. Checks syntax, feeds, speeds, and extents. Identifies potentially dangerous commands before running.

How to Use

1

Upload G-Code or DXF

Upload a .gcode, .nc, or .dxf file.

2

Set machine limits

Enter your machine's working area dimensions and max feed rate.

3

Review validation report

Review detected issues: out-of-bounds moves, invalid syntax, extreme speeds, missing safety commands.

CNC File Validation

Running a G-Code file on a CNC machine without validation is a common source of crashes, broken bits, and material waste. This validator reads your G-Code or DXF and checks it against a set of common safety rules and syntax requirements, helping you catch problems before they cause damage.

Real-World Examples & Use Cases

Machine Safety

Validate a G-Code file from a new CAM tool before running it on an expensive CNC machine.

Frequently Asked Questions

What dangerous commands does this check for?
