This manual provides instructions for using a 5-axis interface board with NC products. The interface board features 5-axis stepper motor drivers, signal processing to ensure smooth transmission, and 5 input interfaces for functions like emergency stop and limits. It provides power and definitions for all interfaces and pins for connecting stepper motors, limits, and controls. The document also provides instructions for configuring MACH3 software to operate the interface board, including setting port pins, output signals, and motor parameters to allow running G-code programs.
