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. NOTE: USB-MC controller is powered from USB port so in its primary function external power supply is not necessary.

In addition, USB-MC has analog input which is not possible to realize via parallel port.Īdditional 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.įor 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.

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. 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 is using USB for communication and USB port is present on all modern systems.Ī large number of functions have been added and existing are improved. Newer computers often do not offer this port. The parallel port is becoming less and less common and is almost obsolete. Considering that controlling task does not need high performance computer, the price for complete control system can now by considerably reduced.Īt 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. Thus, computer CPU is less loaded, so that Mach3 now can work on less powerful desktop, laptop, and even tablet computers. Motion controller USB-MC takes over all real-time tasks that require precision timing. USB-MC does not require installation of Mach3 LPT driver. As external controller, it brings various improvements in comparison to using Mach3 software over parallel port. 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 (圆4) architectures.
