Overview

The Maslow 4 is a complete redesign of the original Maslow CNC concept. Instead of the vertical frame and chain system, the Maslow 4 uses a flat sled that sits directly on the spoilboard, driven by retractable straps. This eliminates the need to build a large vertical frame and significantly simplifies calibration. The ESP32-based controller with WiFi connectivity modernizes the user experience. At $525 for the kit (router not included), it remains the cheapest way to cut full 4x8 foot sheets. The fundamental trade-offs remain: slow speeds, limited Z-depth, and reduced accuracy at the edges. For cutting plywood parts for cabinets, shelving, and furniture, it delivers exceptional value.

Pros

  • Full 4x8 foot cutting area at an incredible price
  • New flat design eliminates the need for a vertical frame
  • Much easier calibration than the original Maslow chain system
  • ESP32 controller enables WiFi-based operation
  • Open-source community with active development

Cons

  • Still slow cutting speed compared to conventional CNC routers
  • Limited Z-axis depth restricts to thin sheet materials
  • New design means less community experience and documentation
  • Accuracy still degrades at the edges of the work area
  • Requires flat, stable surface for the entire 4x8 sheet

Community Sentiment

The Maslow 4 is the only realistic option for full-sheet CNC on a tight budget. Forum members love it for what it is -- a plywood parts cutter -- but warn newcomers not to expect the speed or precision of a conventional gantry CNC.

What owners love

  • Full 4x8 foot sheet cutting for around $525 is nothing short of revolutionary
  • New flat sled design eliminates the vertical frame headache of the original Maslow
  • ESP32 with WiFi makes the user experience modern and wireless
  • Perfect for cabinet makers and furniture builders cutting plywood parts

Common complaints

  • Cutting speed is very slow compared to conventional gantry CNC routers
  • Only cuts thin sheet materials -- 19mm Z depth limits usable projects
  • New design means community documentation is still being built out
  • Accuracy degrades at the edges and corners of the 4x8 work area

Typical upgrades

  • Ridgid R2401 or Makita RT0701C router (required, not included)
  • Improved sled weight distribution for better accuracy
  • Dust collection attachment for the sled
  • Custom anchoring system for more consistent strap tension
