ESS - Ethernet Smooth Stepper Board

Ethernet Smooth Stepper (ESS) Motion Controller

High-Performance External Motion Control for Professional CNC Applications

The Ethernet Smooth Stepper (ESS) is a dedicated 6-axis motion controller that serves as the bridge between your PC and CNC equipment. This professional-grade external motion controller accepts commands from trajectory planning software and produces extremely high-quality pulse trains to drive stepper and servo motor drivers with precision and reliability.

Key Features:

Network Connectivity:

• Connects via Ethernet port or LAN router - no parallel port PC required
• Emulates 3 parallel ports for maximum compatibility
• Works seamlessly with modern computers and network infrastructure

High-Performance Motion Control:

• Generates pulse rates up to 4MHz for smooth, precise motion
• Extremely low jitter compared to parallel port solutions
• Dedicated hardware ensures consistent performance across all Windows versions (XP through Windows 10, both 32-bit and 64-bit)

Extensive I/O Capabilities:

• 51 total I/O pins across 3 parallel port connections
• 20 dedicated output pins
• 15 dedicated input pins
• 16 bidirectional I/O pins (configurable in groups of 8)
• Flexible pin assignment - any input/output can be assigned to any function

Software Compatibility:

• Direct integration with Mach3 and Mach4 CNC software
• Uses standard parallel port pinout for seamless integration
• Dedicated SmoothStepper plugin for both software platforms
• Superior diagnostics and troubleshooting capabilities in Mach4

Professional Integration:

• 26-pin header connections for ribbon cable connectivity
• Compatible with most breakout boards and motor drivers
• Supports stepper and digital servo motor drivers
• Quadrature and CW/CCW modes for high-end motor drivers

Unmatched Support Coverage:

This product is drop-shipped by our partner company CNC49PC, providing you with 3 levels of comprehensive support:

3. Manufacturer Support - Direct access to the original manufacturer's knowledge base

By purchasing through BuildYourCNC, you receive superior support coverage that goes beyond what's available through other retailers - ensuring your success with professional-grade technical assistance at every level.

Applications:

Perfect for controlling mills, lathes, routers, laser tables, plasma cutters, waterjet systems, drag knives, pipe benders, and other CNC equipment. Capable of running two separate machines (not simultaneously) with its extensive I/O capabilities.

Enhanced Setup Options:

For easier wiring and additional safety features, consider pairing with the C25XP Professional Wiring Add-On, which converts the ESS's IDC header connections to convenient screw terminals while adding integrated spindle control and safety monitoring.

Note: Motor drivers required between ESS and motors. 5V output signals with 24-32mA current limiting. Does not support analog or PWM servo drivers.
