CNC Controller for GRBL 1.1f CNC Router Machines

The package includes: 1x Upgraded 3-Axis GRBL 1.1 Control Board and 1x USB cable. The control board's specifications are as follows:

Connection: USB (USB-CH340) Input Voltage: 24VDC (only supports 24VDC input) Control Software: GRBL control (Candle), Universal Gcode Sender Master Chip: Atmel 328P (Arduino Nano) Spindle Drive Chip: MOSFET, recommended 24V DC, current within 10A Spindle PWM Speed: Supported Stepper Motor Support: Maximum current of 2A or less, recommended within 1.5A with additional heat dissipation (any NEMA17 or NEMA23 stepper motor) Supported Operating Systems: Windows XP / 7 / 8 / 10 (32/64 bit), Linux Power Interface: 5.5-2.5mm DC

The upgraded control board features several new functionalities, including: 1. Outer casing to protect the control board during transit and prevent short circuits during use. 2. Power button switch. 3. Integrated stepper motor driver with short-circuit protection and integrated heat-dissipating aluminum alloy. 4. Fan port for active cooling. 5. Offline recognition, allowing simultaneous connection to offline modules and computers, with automatic detection of computer control. 6. Enhanced spindle drive, supporting up to 20,000 RPM spindles for more powerful applications. 7. Improved USB interface, with a plug-in design that is more robust and less prone to damage compared to the original solder-based connection. 8. Increased optocoupler isolation in the spindle drive, resulting in less heat generation and more linear, safer spindle speed adjustment. 9. Addition of emergency stop button port, probe port, and XYZ limit port.

The upgraded control board is compatible with the following CNC engraving machines: 1310, 1610-PRO, 3018, 3018 PRO, and 3018 MAX.

In terms of stepper motor and spindle specifications: - Stepper Motor Drive: A4988 - Spindle Power: 150W - Input Voltage: 24V (12-24V) - Maximum current of 2A or less is recommended, within 1.5A with additional heat dissipation (compatible with any NEMA17 or NEMA23 stepper motor)

The control board supports 3-axis (XYZ) control, as well as spindle and laser module control. It can accommodate both 3-pin and 2-pin laser connections (for 2-pin lasers, please connect to the white "+ s-" interface).
