MakerMade M2 CNC Router

Pros

  • Full 4x8 foot cutting area for sheet goods
  • Improved chain tensioning over original Maslow design
  • MakerMade provides commercial support and warranty
  • Excellent for cutting cabinet parts and furniture pieces
  • Vertical storage takes minimal floor space

Cons

  • Very slow cutting speed compared to conventional CNC routers
  • Accuracy degrades significantly at the edges and corners
  • Limited Z-axis depth restricts to thin materials
  • Requires building a large vertical frame
  • Software can be finicky and requires patience to calibrate

Maslow 4.1 CNC Router Kit

Pros

  • Covers a full 4 x 8 ft sheet for a kit price far below gantry machines of that size
  • 4.1 fixes known Maslow 4 weak points: JST connectors instead of ethernet cables, star-drive screws, larger belt guards and idler gear bearings
  • Automatic calibration measures the anchor geometry, so the frame does not need precise dimensions
  • Packs down to about 350 x 280 mm and can anchor to a floor, bench or simple frame
  • Open-source hardware and firmware with frequent firmware releases and an active forum

Cons

  • Kit was sold out with a waitlist when checked, and Maslow has said a restock will take months
  • Router, bits, anchors and a rigid frame or floor are extra
  • Maker's own accuracy target is +/-0.5 mm and depends on a good calibration, coarser than gantry routers
  • Top speed is 2,500 mm/min and Maslow itself cuts at about 2,000 mm/min, so large jobs take time
  • Maslow says it still needs a fair amount of fiddling to work well
