CNC 4-Axis Kit with ST-4045 Motor Driver, USB Controller Card, Nema23 Stepper Motor and 36V Power Supply
Description: This is SainSmart's new CNC complete kit for engraving DIY. It comes with the necessary and basic parts to make your own engraving machine. The parts are simple and easy to assemble. Specification: Mach3 4 Axis USB CNC Controller card, 100KHz Supports 4-axis linkage; you can connect four stepper motor drives or servo drives. The maximum step-pulse frequency is 100KHz, suitable for servo or stepping motors. Supports automatic probe tool. Supports emergency input. Supports limit switch. Supports connecting electronic handwheel. Requires an external 24V DC power supply to isolate the USB and external port for a more stable system. Includes a 0-10V output port for spindle motor speed control using Mach3 software. Four general-purpose inputs for limit switch, emergency stop switch, probe switch, and other devices. Four general-purpose isolated relay drive output interfaces to control spindle start, forward/reverse pumps, and other devices. Includes a status LED to indicate connection status on the board. ST-4045-A1 Stepper Motor Driver Characteristics: DC power input type: 12V~48V (Typical 36V) Output current: 0.6~4.5A Microstep: 1, 2, 4, 8, 16 Protection: Overheat, over-current, and under-voltage protection Maximum pulse rate: 200KHz Dimensions: 118mm x 87mm x 35mm Net Weight: 253g Working environment: Temperature -15~50°C, Humidity < 90% I/O Ports: 1: DC+: DC power positive pole (Must not exceed 45V to avoid damage) 2: DC-: DC power negative pole 3: A+ A-: Stepping motor one winding 4: B+ B-: Stepping motor other winding 5: PUL+ PUL-: Stepping pulse input +5V (Rising edge effective, duration > 10μS) 6: DIR+ DIR-: Stepping motor direction input (high level for forward, low level for reverse) 7: ENA+ ENA-: Motor enable Stepper motor Switching power supply Model 57HS76 Number of Phases 2-phase Number of Wires 4-wire Phase Voltage 3.08V Phase Current 3A Resistance 1.1Ω Inductance 3.6mH Torque 1.89N·m (270 oz-in) Shaft Diameter 8mm Axial Length 21mm Side Length 57mm Height 76mm Weight 1100g Power Supply Characteristics: AC input voltage range is adjustable via switch. High efficiency and reliability. 100% full load burn-in test. Protections: Short circuit, overload, overvoltage, and over-temperature. Built-in cooling DC fan control. Working frequency: 25 kHz. Input Voltage: 220V/115V. Output Voltage: 36V. Output Current: 9.7A. Output Power: 350W. FAQ: Q: Does the CNC kit use USB to work with the enclosed Mach3 software? A: It only works with Mach3, but the "enclosed Mach3" is a demo that runs only 500 lines of G-code. You will need to purchase a full Mach3 license. The board does not work with Mach4. To run Mach4 or UCCNC, you can buy a separate controller board and use these motors and drivers. Q: Can you control this using a Raspberry Pi? A: No, it cannot be controlled using a Raspberry Pi. Q: Will this support GBL software? A: Did you mean GRBL? This product does not support GRBL software. If you have any other questions, please feel free to contact us for specific information.
