A low cost, upgradable 4040 for hobbyists who want lead screw accuracy and a bigger bed than a 3018. Plan on a trim router upgrade for serious wood cutting.

Pros
  • Lead screws on every axis hold position better than belts for crisp carving
  • A nearly 16 by 16 in bed fits signs and small panels
  • Limit switches, an emergency stop and a Z probe come standard
  • Accepts 65 mm and 69 mm router mounts, so a trim router upgrade is a bolt on job
Cons
  • The 75 W stock spindle is slow in hardwood and too weak for aluminum without an upgrade
  • Rides on round guide rods rather than linear rails, so it flexes more under heavy cuts
  • The offline controller costs extra
