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/

iNC-Mill brings NC/G-code editing, 3D toolpath review, and cutting simulation to iPhone and iPad. Preview material removal for 3-axis milling and turning, inspect FANUC macros, and work with machining files locally. Cutting simulation requires an active subscription. CLOSER, CLEARER 3D TOOLPATH REVIEW • Pick two points on a toolpath to inspect 3D distance, coordinate differences, and path length, with endpoint snapping • Select a precise path position to seek playback, or navigate by move, Z change, cutting section, or tool section • Switch to a tool view and independently lock the viewing direction • Adjust X/Y/Z display scales independently to reveal small variations • Play toolpaths forward or in reverse, with speed controlled independently of play/pause • See the associated code line when available, alongside feed F and spindle S values • Customize path colors, inspect motion counts and travel-distance shares in the legend, and filter paths by playback range Measurements describe toolpath geometry. Curves use the published path segments; these are not measurements of the physical workpiece. BUILT FOR THE SHOP FLOOR • Preview stock material removal during 3-axis milling playback • Open NC files from Files, AirDrop, or other apps • Edit with line navigation, search, and replace • Review very large programs in a focused read-only mode • Inspect 3-axis and 5-axis toolpaths with rapid, feed, and arc motion clearly distinguished • Visualize lathe stock changing as material is removed during turning playback • Trace FANUC macro execution flow and machine state • Organize machine and tool definitions • Calculate feeds, speeds, scallop height, and surface-finish references • Browse practical G/M-code reference content LOCAL-FIRST WORKFLOW Core editing, parsing, preview, simulation, library, and calculator workflows run on device. Your NC files do not need to be uploaded for these tools. USE IT FOR • Shop-floor program checks before machining • On-site edits and troubleshooting • Training and toolpath review • Keeping machining references close at hand iNC-Mill supports human review and visualization. It does not replace professional verification, collision checking, or your machine, tooling, fixture, and workplace safety procedures.
