CNC Router Machine Kit for DIY Mini GRBL Control 3 Axis Milling Machine

The upgraded CNC 3018 PRO DIY Mini CNC Router Kit engraving machine comes in a package that includes: 1 Set of the Upgraded 3 Axis 3018 Pro CNC Router Engraving Milling Machine Kit, 3x Limit Switches (XYZ axis), 1x Emergency Stop, 1x GRBL 1.1f Control Board, 1x 775 Spindle Motor with ER11 Collet, 1x 24V DC 5A Power Supply, 10 x Tip 0.1 mm, 20° φ3.175 mm Drill Bits, 4x Plate Clamps, 1 Set Allen Wrench, 2x ER Wrench, 1x Brush, 1x Spindle Motor Harness 60cm, 3x Stepper Motor Harness 60cm, and 1x 4G USB Flash Drive with the English User Manual & GRBL Software. Assembly is required.

The machine's working area is 300x180x45mm (11.8" x 7.1" x 1.8"), with a frame size of 420x350x270mm (16.53" x13.78" x 10.63"). It features a 775 100W Spindle Motor (24V:10000r/min), a processing thickness of 4.5cm (1.8"), and a height of 6.4cm. The materials used are PA6 nylon and aluminum profile, with a T8 screw rod, lead 4mm, and double copper nut to eliminate backlash. The Spindle Chuck is an ER11 Collet, and the Stepper Motor is a Nema17, 34MM, 1.33A, 0.3N.m, 43oz-in. The Power Supply is a 24V 5.6A Adapter (input voltage 110-240VAC).

The machine supports Windows XP SP3, Win 7, Win 8, Win 10 (32/64 bit), and Linux operating systems, with a PC-USB connection. The software used is GRBL Controller/Candle, supporting G-code files (.nc/.txt/.tape/.gcode). The processing accuracy is approximately 0.2mm.

The 775 Spindle Motor is a 100W, 12-36V model, with a 24V:10000rpm/min performance. It has an M4 screw hole, a 29mm mounting hole pitch, and a 15mm shaft diameter. The package also includes 10 pcs of 0.1mm tip, 20-degree, 3.175mm diameter drill bits.

The upgraded CNC 3018 Pro machine features an Emergency Stop Button and XYZ Axis Limit Switches. The GRBL Controller Board has a USB (USB-CH340) connection, supports GRBL Controller and UniversalGcodeSender software, and operates on 12-24VDC input voltage. It uses an Atmel 328P (Arduino Nano) master chip and a MOSFET Spindle Drive Chip, supporting 12V Stepper Motors with a maximum current of 2A or less, recommended within 1.5A.

Key advantages of the upgraded model include the addition of the Emergency Stop Button, Probe Port, and XYZ Limit Ports, as well as an Outer Casing, Power Button Switch, Integrated Stepper Motor Drive, Fan Port, Offline Recognition, and an Enhanced Spindle Drive. The USB interface has also been improved, and the Spindle Drive's optocoupler isolation has been enhanced.

The control board supports two engraving methods: 24V Spindle Motor and 12V 3A max PWM 3-pins modules. The package includes the Spindle Motor but not the module.

The upgraded CNC 3018 Pro Mini CNC machine is small in size, lightweight, USB-interfaced, and GRBL-controlled, making it a great choice for beginners. It can be used to engrave a variety of materials, including plastic, wood, acrylic, PVC, PCB, and soft metals like copper and aluminum, but not hard materials like jade or very hard textures.
