Sherline CNC Controller Board

• Sherline CNC Controller Board
• Optimized for LinuxCNC control
• Supports 5-30 volts, better at high
• Offers 800 microsteps per revolution
• Reduces motor power to save energy
• Includes panic stop and reset features

The Sherline CNC Controller Board is a sophisticated device designed to manage and control CNC machinery with precision. It is engineered to work efficiently with various software systems, although it is optimized for use with LinuxCNC. The board requires a minimum of an 800 MHz Pentium class computer for optimal performance in frequency mode, ensuring smooth and reliable operation.

This controller board features removable fuses and operates with a voltage range of five to 30 volts, offering better performance at higher voltages. It supports a current of 2 amps in a unipolar configuration, making it suitable for a wide range of applications. The board is capable of microstepping, providing 800 steps per revolution, which translates to 16,000 steps per inch with a .050-inch pitch leadscrew, allowing for high precision in CNC operations.

The board is equipped with a DB25 pinout for connectivity, which includes inputs and outputs for various directional and step controls. It also features headers on the PC board, such as H1, which can reduce motor power to a quarter after three seconds of inactivity, and H3, which can immediately cut power to the drivers in case of an emergency. The RESET header maintains the drivers in a reset condition when necessary.

Note: Ensure that the software used addresses the correct I/O lines for step and direction, especially when not using LinuxCNC.
