What can the CNC 4040 cut?

It is built for wood, plastic and acrylic engraving. Soft woods and plastics cut well; hardwoods and aluminum need very light passes and are slow.

What software does it run?

It uses a GRBL control board over USB and works with GRBL senders such as Candle. You generate toolpaths in a CAM program and send the G-code through Candle.

What bit size does the chuck take?

The ER11 chuck with the 3.175 mm collet takes standard 1/8-inch shank bits. Other ER11 collets can hold different shank sizes.

Does it come assembled?

It ships as a kit that you assemble and square up yourself. Expect to spend time on alignment and on setting motor and axis parameters before the first clean cut.

Is it good for a beginner?

Yes, if you accept a learning curve. The open frame and GRBL setup teach the basics, but you must add your own clamping, dust control and safety precautions.

How does it compare with a 3018 router?

The 4040 has a larger 400 x 400 mm bed and a more rigid aluminum frame than a typical 3018. Both are light-duty machines; the 4040 handles bigger panels.

Our take on the CNC 4040 Router Machine

The CNC 4040 is a desktop engraving machine with a 400 x 400 x 83 mm working area, an aluminum frame, three 42 stepper motors and a GRBL control board over USB. It engraves wood, plastic and acrylic, and the ER11 chuck with a 3.175 mm collet takes common small bits. It suits hobbyists, students and small shops learning CNC on a compact footprint. Against larger routers it gives up spindle power and rigidity, so it is a light-duty learning tool rather than a production machine.
