CNC USB controller MK 3/4 (4 axis)

CNC motion controller is a link between personal computer and drivers for stepper motors. It uses USB port which is available on all modern computers and laptops. This is a complete (software/hardware) solution and it does NOT require any additional software (Mach3 is NOT needed).

The USB CNC controller is compatible with most step/dir drivers. It can be used as direct replacement for many parallel port break-out boards.

This controller is designed for Hobby and light industrial use.
