3 Axis/4 Axis MACH3 USB Motion Control Card Interface 2000KHz

The MK4-IV Mach3 Motion Card is a 4-axis motion control card designed for CNC machines. It offers various features and specifications to enhance the performance and functionality of the machine. 


  • Dual-Processors: The card is equipped with dual processors, one for ARM and one for FPGA, providing increased processing power for improved performance.
  • Mach3 Compatibility: The card is compatible with all versions of Mach3 software, allowing you to control the CNC machine using this popular software. However, it is not compatible with Mach4.
  • Operating System and USB Compatibility: It is designed to work with 32-bit operating systems for Windows (not compatible with Mac OS). The USB connection does not require driver installation and supports plug-and-play functionality on all Windows versions.
  • USB Hot-Swapping: The card supports USB hot-swapping, meaning you can unplug and plug in the USB cable while Mach3 is running without any connection issues.
  • 4-Axis Linkage: The card supports 4-axis linkage, allowing precise control over the movement of the CNC machine.
  • Maximum Step-Pulse Frequency: The card has a maximum step-pulse frequency of 2 MHz, enabling high-speed and precise control. It can be connected to both servo drivers and stepper drivers.
  • Indicator Light: The card features an indicator light that shows various working statuses, including USB connection and Mach3 connection.
  • Inputs and Outputs: The card provides 16 inputs and 8 outputs. The inputs are isolated and can handle up to 5 mA of input current and 25V maximum voltage. The outputs are isolated open collector outputs with a drive current of 20 mA at 5V.
  • Onboard Isolated Power Supply: The card has an onboard isolated power supply, eliminating the need for an external power supply.
  • Spindle Speed Control: The card supports spindle speed control with options for PWM output, analog voltage output (0-10V), and pulse + direction output.
  • Support for XHC Series MPG: The card is compatible with XHC series wireless electronic Mach3 MPG devices such as the WHB04 MPG.
  • Aluminum Shell: The card is housed in an aluminum shell, which effectively shields interference and ensures stable and reliable performance.


  • CPU: Dual-Processors (ARM and FPGA)
  • Axis Output Control: 4-axis, Isolated open collector output (5V, 20mA), Pulse + direction output, Output frequency: 2MHz, Isolation Voltage: 3.5KV
  • Spindle Inverter Output: Analog voltage output (0-10V), PWM output (5V, 1KHZ, Duty: 0-100%), Pulse + direction output (5V, 15Hz to 4KHz)
  • Spindle Speed Input: Isolated input (5V pulse signal), Isolation Voltage: 3.5KV
  • 8 Outputs: Isolation: 50mA, 25V, Isolation Voltage: 3.5KV
  • 16 Inputs: Isolated inputs (5mA, maximum voltage 25V), Isolation Voltage: 3.5KV, Mach3 Port Position: P1 Port
  • USB Interface: USB 2.0 compliant
  • Size: 184 x 110 x 30mm (7.2 x 4.3 x 1.2 inches)


The MK4-IV card is suitable for various CNC machine applications, including laser, plasma, and flame-cutting machines, wood, advertising, and marble CNC routers, milling machines, automatic production equipment, and automatic welding machines.
