G-Code Guardian - Manufacturing Validation Tool

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. The tool provides instant validation (under 1 second) with comprehensive safety checks to prevent costly mistakes and machine damage.

Key Features:

• Drag-and-drop file upload for .nc, .min, and .txt G-code files
• Instant validation with three severity levels: Critical Issues, Warnings, and Info/Optimizations
• Beautiful syntax highlighting for G-code with line numbers using Prism.js
• Approval workflow with reviewer tracking and notes
• Revision history tracking for parts
• Clickable validation issues that jump to specific lines in code
• Dark mode support
• Mobile-friendly responsive design
• SQLite database with Drizzle ORM
• Dashboard with statistics and recent programs

Validation Engine Checks:

• Critical Issues: G0 rapid into negative Z, missing feedrates, unsafe tool changes
• Warnings: Minified code, probing variables, duplicate tools, back-spotface cycles
• Optimizations: Identical roughing passes, long cycle times, repeated drilling cycles

Technical Implementation: Built with Next.js 15, TypeScript, and SQLite for a lightweight, fast solution. The validation engine parses G-code line by line, tracking machine state and flagging potential issues based on manufacturing best practices. All validation happens client-side for speed and security.

Business Impact: Prevents machine crashes, reduces scrap parts, ensures manufacturing quality, and provides a clear approval trail for regulatory compliance. Typical ROI is achieved after preventing just one major machine collision.
