Benchmark Scores
Side-by-side score comparison across all five benchmark dimensions.
Overall
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
Original Maslow CNC Router Kit (chain-driven)
Pros
- Cuts full 4x8 foot sheets of plywood
- Extremely low cost for the work area size
- Open-source hardware and firmware with an established support forum
- Upright sheet support uses less floor depth than a horizontal 4x8 bed
- Great for furniture and large panel projects
Cons
- Very slow cutting speed
- Accuracy decreases at edges and corners of the work area
- Cutting depth depends on the router, bit, sled and Z-axis conversion
- Requires a rigid frame, sled setup and calibration
- Not suitable for precision work or small details
