✨ What's Included

3D Machine & Simulation

• High-fidelity gantry VMC (base, T-slot table, columns, moving bridge, quill, spindle)
• Real material removal — the workpiece is actually milled as the tool follows the program
• Per-tool geometry — 8 tools (end mills, drills, ball nose, chamfer, face mill, spot drill, reamer) each carve with their real diameter
• Live toolpath rendering with arc tessellation, PBR materials, soft shadows, environment reflections

Controller Console

• LCD-style DRO with live X/Y/Z coordinates + cutting indicator
• Spindle RPM / feed / tool / coolant status lamps
• Run / Dry Run / Machine Lock simulation modes
• Timeline scrubber, cycle speed (0.25×–10×), feed/rapid/spindle overrides
• Optional stop (M01) + Block skip (/) toggles
• Keyboard shortcuts (Space / ←/→ / R)

G-code Programming

• Syntax-highlighted editor with current-line execution tracking
• Click-a-line-to-seek
• Parse diagnostics with inline error reporting
• 26 ready-to-run example programs (Beginner → Advanced)
• Program library — save/load/export/import to localStorage, 15 code snippets

Learning Suite

• Feeds & speeds calculator (RPM, feed, MRR, spindle power, DOC/WOC recommendations)
• 8-material library (Aluminum 6061/7075, Mild Steel, Stainless 304, Brass, Copper, Delrin, Oak)
• 65-code reference (G/M/T/F/S/Z) — searchable & category-filtered
• Educational guide with G-code primer & coordinate system
