NOTE: We are still working on sourcing the cables at a reasonable cost. In the mean time the ESS will ship without cables at a discounted price!

We will point you in very well priced alternatives on Amazon. We cannot compete with them nor do we want to mark our prices up. So we pass the savings on to you.

World renowned high-performance external motion controller for Mach3 and Mach4. We are an official reseller for the Ethernet Smoothstepper in the UK. Our bundle includes an Ethernet Smoothstepper,  3  high quality  26 pin header to 25 pin D connector like the parallel port cables and a 3m long CAT 6 Ethernet Cable.

The Ethernet SmoothStepper (ESS) is a high-performance external motion controller for Mach3 and Mach4. Because it has a connector that conforms to the Parallel Port standard, it integrates seamlessly with most devices that the Parallel Port driver of Mach interfaces with. It accepts high-level commands from Mach and produces Step & Direction signals that are compatible with nearly all step & direction motor drivers (it also has a quadrature mode for high-end motor drivers, but those are not common). Because it is a dedicated hardware device, it is capable of producing pulses at very high frequencies and with extremely low
jitter compared to the Parallel Port driver and microcontroller-based solutions. In addition, the SmoothStepper is able to run on any flavor of Windows, both 32‑bit and 64‑bit. Mach will run under 32-bit or 64-bit, but an external controller such as the SmoothStepper is needed for 64-bit editions.

We use the Ethernet Smoothstepper in our own machines to ensure reliable  communication between them and the PC . As the Ethernet variant is significantly less susceptible to electrical noise, generated for example by the starting of the spindle, we only supply this one from stock. However we are able to supply the USB variant as well on a slightly longer lead time.

Please note that the ESS requires a 5V supply to function.

    Now on the 4th ESS Smooth stepper, equipped machine and can confirm they are simply, superb. Ultra reliable with a large amount of technical information, from all the usual sources.

    Couple it to an MB3 and you have a fantastic system. Inputs and outputs, like no other.

    Service from Emvio, is excellent.

      Hi Andrew!
      Thank you for leaving the review. Very glad you are happy with the service and the item you bought. Will need to look into the MB3 in the new year, people are starting to ask for it a bit more now.
      Feel free to show us your electronics setup and machine!

    Not the first time I bought this board, so I am satisfied, however the price is a bit steep for what it is, as these days boards could be made quite cheap.

      thank you for taking the time to write the review, we really appreciate this. I really wish I could sell at a lower price…
      The price reflects the cost, so at the moment we are very constrained. The manufacturer has increased prices and the global shortage of processor chips has further increased the costs.. Add the issues with couriers and handling and poof…
      We did keep our price the same from 2014 when we first started selling the ESS until last year too. When things calm down, I am will definitely recalculate the prices!
