CNC USB controller Mk3/4 (4 axis)


CNC USB controller Mk3/4 (4 axis)


Product Description

USB to CNC is now a reality! CNC motion controller is a link between personal computer and drivers for stepper motors. It uses a 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). USB CNC controller is compatible with most step/dir drivers. It has the same pinout as popular PICStep and PMinMO drivers. It can be used as direct replacement for many parallel port break-out boards.
