G-Code scanner lets you view STL files before 3d printing. It is a photo scanner for CNC machine code and STL viewer. This eas 3D printing stl viewer tool, G code viewer for CNC, CNC G-Code & STL Viewer gives machinists, programmers, and engineers a powerful pocket-sized tool for inspecting, simulating, and sharing toolpaths—anywhere the job takes you. WHY CHOOSE CNC G-CODE & STL VIEWER • Instant insight: Load FANUC- or HAAS-style G-code in seconds and watch real-time toolpath playback before a single chip is cut. • Error prevention: Catch gouges, over-travels, and syntax issues early so you protect cutters, fixtures, and machines. • STL Viewer: Upload and view STL models quickly and easily, right from your phone • Universal compatibility: Works with Gcode from most major machine tool companies • Shop-floor ready: Dark theme, large coordinates, and touch-friendly controls keep the data readable in bright coolant-splashed environments. • Cloud or local: Import files from email, Google Drive, Dropbox, or straight from your device’s storage—no forced sign-ups. WHO IT’S FOR • Job-shop machinists verifying edits right at the machine • Manufacturing engineers adjusting code on the production floor • CAD/CAM programmers teaching technicians how to debug code • Instructors demonstrating CNC concepts in the classroom • Hobbyists running desktop routers or 3D printers that accept G-code SAVE TIME, SAVE TOOLS, SAVE MONEY Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
