Genmitsu 4040-PRO CNC Router Kit
Core cutting machine providing 400x400mm work area for hobby projects.
The Genmitsu 4040-PRO is a GRBL-based desktop CNC with a sturdy aluminum frame, NEMA17 steppers, and 300W spindle—ideal for budget builds. It handles wood, acrylic, PCB, and soft aluminum up to 18mm deep cuts.
At $800, it punches above toy-level 3018 machines (too small/flexy) but under premium Shapeoko ($2000+). Users praise its accuracy (±0.1mm) and easy assembly for beginners.
Value king: Larger area than $500 competitors, upgrade-ready ports, and 4.5+ star reviews from 1k+ makers.
