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
