Designed for seamless compatibility with Mach3 and Mach4 software, it eliminates the need for legacy parallel port PCs, offering professional-grade control with 51 I/O ports and robust online support—all proudly made in the USA. ## Description The Ethernet SmoothStepper is an external motion control device that connects to the Ethernet port of a computer. It accepts commands from a software package such as Mach3, and produce very high quality pulse trains that drive step & direction motors. Features: Works through Ethernet. Connects to the Ethernet ports or LAN router so there is no need for a PC with parallel ports. It simulates 3 parallel ports. Generates pulse rates of up 4Mhz. Works directly with Mach3, Mach4 ( not includes MACH3, MACH4) Online Support Forum. Has 51 I/Os. Made in USA Review: The Most Painless Thing I've Done in CNC - I was prepared for all sorts of issues, but it was the most painless thing I've done in CNC. I had been using an old Windows XP-based, Pentium 4 computer to run my CNC tools with Mach3 since 2007, but the computer started having issues and working unreliably. I tried to replace it with another old, virtually identical machine, and found it had different hardware issues. In the intervening months, I went through two other computers, went to Windows 7 64 bit - only to learn Mach3 won't support 64 bit windows, and finally running LinuxCNC. I bought this smooth stepper to move back to Mach3 on a younger, faster Windows 7 computer. It worked fantastically. The ESS has three parallel ports on it, and with very little effort, I am able to control all three of my CNC machines under Mach3 just by running three different configuration files. I've been running it a couple of months now and it works great. Between their online support videos and installation software it was easy to set up and get running. I could have avoided a few months of pain swapping computers and going down the whole LinuxCNC path if I had done this sooner. The Warp9 Ethernet Smooth Stepper is the way to go. Review: PERFECT! - This card is the best I absolutely love it I installed for my cnc machine every bit worth the money I wanted to get away from the old computer and windows xp to my new computer and and didn't want a usb connection so now I'm using an ethernet connection and speed of T-100 connection I love it pus i connected 2 break out boards to this one card for more input and output signals for vacuum pump, limit switches, homing switches, E- stop, etc. etc. bought it from warp 9 ## Features - Ethernet SmoothStepper CNC Motion Controller - Simulates three standard parallel port interfaces. - Operate a CNC machine from an Ethernet connection. - Works seamlessly with Mach3 Software (sold separately). - Pulses at rates over 4 Mhz! ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00R8FNLW4 | | Batteries Included? | No | | Batteries Required? | No | | Best Sellers Rank | #464,232 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #553 in Motor Speed Controllers | | Customer Reviews | 3.9 3.9 out of 5 stars (70) | | Date First Available | December 19, 2014 | | Is Discontinued By Manufacturer | No | | Item Package Quantity | 1 | | Item Weight | 0.353 ounces | | Manufacturer | Warp9 Tech Design Inc. | | Part Number | B-ESS-Ethernet SmoothStepper | | Product Dimensions | 3.75 x 2.75 x 0.5 inches | ## Images ![Ethernet SmoothStepper CNC Motion Controller - Image 1](https://m.media-amazon.com/images/I/71K8xBG0fRL.jpg) ## Questions & Answers **Q: can you run other applications on your pc simultaneously without missing any steps when using this device?** A: Yes you can. The Ethernet SmoothStepper actually transfers all of the complicated processing to the device, rather than your computer. That frees up your computer to be used simultaneously while running the machine. That being said, we would still recommend you have a computer dedicated to running the machine. **Q: Is this a 'stand-alone' module that does not require a separate BOB (breakout board)?** A: You will need a breakout board and/or a IDC26 to DB25 parallel cable adapter. This will all depend greatly on your setup. **Q: Is this a good choice to upgrade and fix known issues with the control system on my Chinese tabletop 6040? If so, what else do you think would be good** A: I don't know what issues you are having but the ethernet smooth stepper works fine on my converted Bridgeport Chinese clone. **Q: I'm confused on where to start. Is this the right choice for plasma table? I wanted Mach 4 but sounds like 3 works best with this board??** A: This board will work with Mach3 or Mach4. If you already have Mach3 then no problem, use it. If you are starting new then it would probably be better to go with Mach4. There are several Break Out Boards (BOB) that will work with the SmoothStepper and what one you want to use depends on how the hardware of the machine you want to connect to is configured. ## Customer Reviews ### ⭐⭐⭐⭐⭐ The Most Painless Thing I've Done in CNC *by M***K on March 25, 2017* I was prepared for all sorts of issues, but it was the most painless thing I've done in CNC.
