USB-MC MOTION CONTROLLER

USB-MC is motion controller designed for use with popular Mach3 CNC control software in Windows XP, Vista, 7, 8, 8.1 and 10 operating systems with 32-bit (x86) and 64-bit (x64) architectures. As external controller, it brings various improvements in comparison to using Mach3 software over parallel port. USB-MC does not require installation of Mach3 LPT driver.

Motion controller USB-MC takes over all real-time tasks that require precision timing. Thus, computer CPU is less loaded, so that Mach3 now can work on less powerful desktop, laptop, and even tablet computers. Considering that controlling task does not need high performance computer, the price for complete control system can now by considerably reduced.

At the same time, much higher output frequency for step signal (up to 250 kHz) is achieved and much better quality of output than it is possible with parallel port regardless of performances of used computer.

The parallel port is becoming less and less common and is almost obsolete. Newer computers often do not offer this port. USB-MC is using USB for communication and USB port is present on all modern systems.

A large number of functions have been added and existing are improved. PWM output can have much higher frequency and higher resolution, PWM power compensation in relation with feedrate is added, implemented hardware MPG mode, more detailed debouncing adjustments for all input signals, and much more.

USB-MC motion controller has 16 digital outputs and 14 digital inputs in comparison to 12 digital outputs and 5 digital inputs that are available from parallel port. In addition, USB-MC has analog input which is not possible to realize via parallel port.

In order to achieve compatibility with existing systems which use input/output cards (breakout boards), USB-MC has 25-pin LPT connector built-in. That means that USB-MC can be used easily with existing systems which use parallel port.

Additional inputs and outputs are available via appropriate connectors, and via add-on input/output boards that can be easily connected to USB-MC motion controller.

Mach3 plugin contains integrated latest compatible version of firmware so in case that firmware has to be updated, this process is automatic and easy for user.

For connection of USB-MC motion controller with PC, it is important to use high quality cable, as short as possible, preferably not longer that 1.5m.

NOTE: USB-MC controller is powered from USB port so in its primary function external power supply is not necessary. However, external power supply is required if input/output add-on card UIO-1 is used because this card requires higher voltage than 5V that is available from USB port.

USB Driver

In most cases, if Windows 7 or newer operating system is used, Windows will automatically find and install required driver so that manual installation should not be needed. Otherwise, if Windows does not find driver, it will ask for location on local computer to read it from. In that case download and unpack one of available drivers.
