CNC Maker Assistant

Features
Read full description

CNC Maker Assistant is a workshop tool for hobby CNC users — not a chat app. IMPORT & VISUALIZE Import your G-code (.nc, .gcode, .ngc, .tap, .cnc) and see the actual toolpath rendered in 3D, with a 2D top-down mode too. Orbit, pan, and zoom with touch gestures, jump to any CAD-style view (Top/Front/Iso/etc.), or play the program back move-by-move with a scrubber — see exactly what your machine will do before you cut. DETERMINISTIC SAFETY CHECKS Every file is analyzed by real, deterministic logic — not a language model guessing. Rapid moves into stock, dangerously low Z clearance, a missing spindle start: these are found by code, then explained and prioritized by AI. The AI never invents a warning that the analyzer didn't already find. FEED & SPEED CALCULATOR Pick your material, tool diameter, flute count, and machine's max RPM, and get a starting feed rate and spindle speed from real formulas and curated cutting-data tables — aluminum, steel, acrylic, HDPE, wood, and more. The AI explains the "why" behind the numbers; it never calculates them. CNC KNOWLEDGE, GROUNDED Ask questions in a focused chat — tool selection, troubleshooting chatter, G-code reference — and get answers grounded in a curated knowledge base, not generic web search results. BUILT FOR THE WORKSHOP Big touch targets, offline-capable calculators, and a toolpath viewer designed to be legible with gloved hands next to a running machine. Cutting recommendations are conservative starting points to test on your own machine — always verify feeds, speeds, and workholding before running a real job. Free to start: 1 AI-explained G-code import, 5 feed/speed explanations, and 5 chat messages per day. CNC Maker Assistant Pro removes all three daily limits.
