XHC Mach4 CNC Controller

mach4 interface board/mach 4 cnc controller board

XHC Mach4 USB Breakout Board 3 4 6 Axis

This is the latest generation Mach4 cnc motion control card, which is the fourth generation calling MK3-M4. It could work under Mach4 software. The maximum step-pulse frequency is 2000 KHz. Now MK3-M4 is stronger, more stable and better performance than other version

Current Price

1.Dual-Processors, ARM+FPGA, More processing power
2.Support all versions of Mach 4.
3.Work under Windows 32-bit operating system (not including Mac OS)
4.Support spindle speed feedback function.
5.USB jack does not need to install the driver, plug and play under all versions of Windows.
6.Full support USB hot-swappable, USB connection status monitoring at any time. Under Mach4 working state, USB cable unplugs and then plugs in, but also the normal connection.
7.Supports 3-axis linkage.
8.Maximum step-pulse frequency is 2000 KHz, can connect servo driver and stepper driver.
9.The indicator light indicates various working status, such as USB connection, Mach3 connection and so on.
10.16 input IO, 8 output IO, Supports extended I / O control.
11.Onboard isolated power supply, not need external power supply.
12.All IO port fully isolated, strong anti-interference, stable performance.
13.Support spindle speed PWM output; support spindle pulse and direction output; support spindle speed output from 0 to 10V analog voltage.
14.Support XHC series of wireless electronic Mach4 MPG, such as WHB04B-4-M4 MPG.
15.With an aluminum shell, effectively shielding interference, stable and reliable performance

Mach3 VS Mach4

Mach4 is an upgraded version of mach3, 90% of their functions are the same, and can be used in lathes, milling machines, engraving machines, plasma cutting and other industries


  1. When processing files, Mach4 optimizes the speed of output data, and does not rely on FIFO to synchronize external devices
  2. Optimize the processing of HID, keyboard and other input devices, and respond faster to input events
  3. Optimized the internal algorithm to make the work more stable
  4. Simplified the parameter setting, and the operation is simpler
  5. Mach3 is a direct mail version with complex functions, but Mach4 has multiple versions for different applications
