Specification:

• Mach3 4 Axis USB CNC Controller card, 100KHz

1. Supports 4-axis linkage; you can connect four stepper motor drives or servo drives.
2. The maximum step-pulse frequency is 100KHz, suitable for servo or stepping motors.
3. Supports automatic probe tool.
4. Supports emergency input.
5. Supports limit switch.
6. Supports connecting electronic handwheel.
7. Requires an external 24V DC power supply to isolate the USB and external port for a more stable system.
8. Includes a 0-10V output port for spindle motor speed control using Mach3 software.
9. Four general-purpose inputs for limit switch, emergency stop switch, probe switch, and other devices.
10. Four general-purpose isolated relay drive output interfaces to control spindle start, forward/reverse pumps, and other devices.
11. Includes a status LED to indicate connection status on the board.

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.
