Should I buy an Ethernet SmoothStepper (ESS) or a USB SmoothStepper (USS)


Staff member
The Ethernet SmoothStepper (ESS) is our flagship product and is much more capable than the USS in terms of features, capabilities and electrical noise immunity. We recommend that anyone considering a Mach compatible motion controller should buy an ESS.

The USS is limited to only Mach3 and is more sensitive to electrical noise. The USS should only be purchased to replace an existing USS, and even then you should consider replacing it with an ESS, since the ESS can use the break out boards attached to ports 1 and 2 of the USS.

Here are the product details for our SmoothSteppers.

You can buy a SmoothStepper from us here.

This is our Getting Started Guide that will answer most of your questions and show you how to set it up.
