High-quality 3-axis GRBL controller board designed for reliable CNC control and easy setup. Key benefits Reliable motion control: Built from high-quality materials and components to provide stable, precise movement for X/Y1/Y2/Z stepper motors — ideal for repeatable engraving and cutting. Wide power compatibility: Accepts DC 12–48V power input so you can use a broad range of stepper drivers and spindle setups without changing controllers. Simplified setup and operation: GRBL-based control with an included USB cable lets you connect directly to a computer for straightforward configuration and operation. Flexible system expansion: Multiple connector options (2pin/3pin/2pin-2pin) plus dedicated ports for a 12V fan let you add servos, offline controllers and limit switches without complex rewiring. Stable spindle support: Supports spindle motors up to 500W at 48V, delivering consistent power output for reliable cutting and engraving results on DIY projects. Features and important specifications Control: GRBL-compatible 3-axis controller Power input: DC 12–48V Motor connectors: X / Y1 / Y2 / Z stepper motor ports Additional connectors: 12V fan port; interface options 2pin, 3pin, 2pin-2pin for peripherals Supported peripherals: Servo motors, offline controllers, limit switches Spindle compatibility: Up to 500W at 48V Connectivity: USB connection included (USB cable supplied) for direct PC control How this solves common problems Removes wiring complexity: Clear, dedicated ports for stepper axes and peripherals reduce the time and errors involved in building or upgrading a CNC machine. Accommodates a range of setups: The 12–48V input and 500W spindle support allow you to use stronger spindles and different motor configurations without swapping controllers. Improves reliability and repeatability: High-quality materials and stable power output help produce consistent machining results across runs. Typical applications Small to medium CNC engraving and cutting: Wood, acrylic, soft metals and other materials on desktop or hobbyist machines. DIY CNC builds and upgrades: Replace or upgrade a controller on home-built machines while keeping compatibility with common peripherals. Prototype machining and small production runs: Reliable motion control and spindle power for repeatable cuts and engravings.
