TM3018

TM3018 refers to a family of small, desktop CNC routers commonly marketed as TM-3018 or TM3018. These machines are designed for hobbyist engraving and light milling, offering a compact work area typically around 300 by 180 millimeters. They are sold as kits or assembled units and are widely used for wood, acrylic, plastic, and PCB fabrication projects.

Design and components

TM3018 machines usually feature a three-axis configuration with a frame built from aluminum extrusions or acrylic panels. The X and Y axes use coarse lead­screws or ball screws with linear bearings or rods, while the Z axis employs a leadscrew or spring-loaded mechanism. Stepper motors (commonly NEMA 17) drive each axis, and a GRBL-compatible control board coordinates movement. Power supplies are commonly around 24 volts, and control boards may use A4988 or DRV8825 stepper drivers. The spindle or router can be a small DC brushless unit or a compact spindle (often fueled by a 24V supply), with typical spindle speeds in the range of several thousand to tens of thousands RPM.

Control and software

Operation relies on G-code sent from a computer to the machine’s control board, usually via USB. GRBL firmware is a common foundation, and users often employ software such as Candle, Easel, or universal CAM programs to generate toolpaths. Calibration tasks include setting steps-per-millimeter, squaring the axes, and securing fixtures to minimize vibration.

Capabilities and limitations

TM3018 machines are suitable for hobby projects involving wood, acrylic, and soft plastics, and can perform light milling on aluminum under constrained conditions. They are not designed for high-precision metalworking or heavy-duty cutting. Performance depends on tool quality, rigidity, feed rates, and proper calibration.
