Easy Assembly, Quiet, and Affordable CNC Router
Assembly is straightforward, noise levels are low, and the price is relatively affordable. No issues have occurred when machining 6061 aluminum exclusively. About an hour was spent tramming and shimming after assembly to maximize accuracy. As a first machine, prior research into milling made the hardware side predictable, while CAD and CAM design proved the most difficult part. The only regret is not waiting a couple of months for a price drop. Tooling lines are visible but the surface is smooth to the touch.
Pros
- + easy assembly
- + low noise
- + relatively cheap
- + zero issues
- + handles 6061 aluminum
Cons
- − price dropped shortly after purchase

Good value with minor issues
This CNC router offers good value and cuts aluminum reasonably well for its size. After roughly 50 hours of use on wood and aluminum, an e-stop error appeared. The cause was debris in the Y axis limit switch connector; cleaning it resolved the problem. Upgrading to a 1/4-inch spindle nut is recommended to improve cutting capability.
Pros
- + good value
- + cuts aluminum decently for its size
- + easy fix for e-stop error
Cons
- − e-stop error after about 50 hours of use

Sturdy Beginner CNC with Useful Features
This CNC router has a sturdy frame and detailed labeling for limit switches and wiring. It includes an adjustable RPM knob with digital display, an E-stop, and limit switches that make it hard to crash. The router does not turn on or off automatically, and the Y-axis lacks rails similar to the X-axis. A vacuum clamp from the same brand does not align with the table's bolt pattern, requiring drilling. The power switch on the router is useful for tool changes and setting Z-axis during G-code operations.
Pros
- + sturdy frame
- + detailed labeling
- + adjustable RPM with digital display
- + E-stop
- + limit switches
- + updated X-axis rails
- + power switch useful for tool changes
Cons
- − no automatic router on/off
- − Y-axis lacks rails similar to X-axis
- − vacuum clamp bolt pattern misaligned
- − requires drilling table for clamp
