This drive system is suitable for use with new, used, retrofitted or OEM CNC machines equipped with unipolar or bipolar stepper motors up to 3.5A per phase. It is available in inch or metric configurations and with worldwide voltage options, tailored to the specific parameters of your machine.

Advanced parameter supervision (APS) continuously monitors position, velocity and acceleration on all axes, preventing over-travel and other mechanical damage due to mis-configured soft limits or other exceptions during normal operation.

CNC-4AX may be connected directly to a computer parallel port using the supplied cable, or to a dedicated motion controller with a step/direction type interface. Known compatible motion controllers include Warp9 SmoothStepper (USB), OEMTech ncPod (USB), Geckodrive G100 (USB/ethernet) and others.

CNC-4AX machine parameters are not user-programmable at this time. We supply a simple worksheet for you to describe the applicable machine, and initial programming is included in the purchase price. Reprogramming to suit new machines is possible, with a service charge of $100 plus return freight.

A generous discount schedule and various customisation options are available for volume customers, including your own front and back panel artwork, start-up screen and firmware strings. We can also supply tools to assist you with end-user support, including setup guides and configuration files for popular CNC software, and pre-programmed "demo plug" dongles to demonstrate machine operation or debug controller problems without involving any computer or software.
