G-Code Guardian - Manufacturing Validation Tool
Production-ready G-code validation system for CNC machining with instant validation, syntax highlighting, approval workflows, and comprehensive safety checks.
About This Project
G-Code Guardian is a specialized web application built for manufacturing operations to validate and approve G-code programs before they run on CNC machines. Provides instant validation (under 1 second) with comprehensive safety checks.
Key Features:
- Drag-and-drop file upload for .nc, .min, and .txt G-code files
- Instant validation with three severity levels
- Beautiful syntax highlighting with line numbers
- Approval workflow with reviewer tracking
- Revision history tracking
- Clickable validation issues
- Dark mode support
- Mobile-friendly responsive design
- Dashboard with statistics
Validation Checks:
- Critical Issues: G0 rapid into negative Z, missing feedrates, unsafe tool changes
- Warnings: Minified code, probing variables, duplicate tools
- Optimizations: Identical roughing passes, long cycle times
Business Impact: Prevents machine crashes, reduces scrap parts, ensures quality, provides approval trail for compliance. Typical ROI achieved after preventing just one major machine collision.
