AnoleX 4030-Evo Ultra 2: All-Metal CNC Router
- Upgraded Φ65mm Trim Router with 800W capacity and ER11-1/8″ collet, 6-speed range (8000-24000 RPM).
- Dual linear rails on each axis (X/Y/Z) with 1204 ball screws for precision and rigidity; enhanced X/Y dust protection.
- GRBL_ESP32 firmware (GRBL 1.3a) enabling advanced features like 4th axis, laser engraving, coolant control, and probe support.
Designed for metal and mixed-material projects, this model emphasizes solid frame construction and upgraded drive components to resist flex during heavy cuts. The combination of dual rails and ball screws supports accurate, repeatable movements at moderate to high feed rates.
LUNYEE 3018 PRO MAX CNC Router
- 500W spindle delivers strong performance for metals and plastics; high-speed up to 12000 RPM.
- All-metal structure with reinforced aluminum profiles; no major plastic components in the main frame.
- Extra-long Z travel (up to 80 mm) for taller workpieces; upgrade kit options noted for precision.
Suitable for smaller metal tasks and robust wood/PMMA work, this model emphasizes rigidity and a compact footprint with a clear upgrade path for higher spindle power if needed.
Genmitsu 4040-PRO MAX CNC Router
- All-metal frame with steel HSS tubes and dual Y-axis rails; lead screws ensure smooth motion.
- Upgraded control box with dust-proof metal housing and Toshiba TB6S109 driver; supports air assist and MPG.
- Broad compatibility with various spindle mounts and future upgrades (65mm/69mm) for more power options.
The 4040-PRO MAX focuses on stable, precise motion with an emphasis on a durable control system and expandable spindle compatibility, making it a versatile option for metal carving and engraving tasks.
AnoleX 3060-Evo Max: All-Metal, 800W Router
- Bed size 300 x 600 mm with 300 x 600 x 73 mm effective workspace; suited for larger metal projects.
- 800W trim router with 65 mm spindle mount; upgrade path to 1.5 kW spindle kit enhances cutting capacity and precision.
- Dual MGN-15 linear guides and 1204 ball screws for high rigidity; optional 1204 ball screw upgrade kit.
Designed for metal-focused work with a larger working area, this model balances power, rigidity, and upgrade paths for heavier cutting needs.
AnoleX 3030-Evo Max: All-Metal, 800W Router
- 800W trim router with 65 mm spindle mount; upgradeable to 1.5 kW spindle for increased metal-cutting capacity.
- Dual MGN-15 linear guides and T8 lead screws provide rigidity and accurate motion; 1204 ball screw option available.
- Nema 17 stepper with possible upgrade to closed-loop motors for improved torque and step consistency.
Compact yet capable, the 3030-Evo Max emphasizes upgradeability and reliable metal cutting performance within a smaller footprint.
Buying Guide: Key Purchase Considerations
- All-metal construction: Look for a rigid frame with dual linear rails and robust ball screws to minimize flex during metal cutting.
- Spindle power and upgrades: A base 800W spindle is common in metal-focused units; assess upgrade paths to 1.5 kW or higher for tougher metals and faster cycles.
- Drive system and control: GRBL-based boards with ESP32 support offer advanced features; closed-loop motors reduce missed steps in demanding cuts.
- Working area vs. material thickness: Larger beds help with multi-piece projects but require stronger frames; ensure your chosen size accommodates workpiece thickness and clearance.
- Dust protection and maintenance: Machines with enclosed dust shields and easy access for maintenance reduce downtime and wear on rails and screws.
- Upgrade ecosystems: Prefer models with upgrade kits (ball screw kits, higher torque spindles, larger spindle mounts) to extend the machine’s lifespan as needs evolve.
- Software and firmware: Firmware like GRBL 1.3a enables features such as laser engraving, 4th axis, coolant control, and probe functionality; offline control options can aid workflow when not connected to a computer.
- Community and support: A model with active user forums, tutorials, and official support reduces learning curves and troubleshooting time.
