Description

  • Sherline Mill CNC Kit with High-Torque Stepper Motors
  • Facilitates custom CNC setup integration
  • Includes 4-axis driver box and power supply
  • Features high-torque NEMA #23 motors
  • Allows 4th-axis rotary table expansion
  • Supports user-chosen control software

The Sherline Mill CNC Kit with High-Torque Stepper Motors is designed for individuals who wish to utilize their own computer and software for CNC milling operations. This kit facilitates the integration of personal computing systems with Sherline's CNC-ready mills, providing a flexible solution for custom setups. The package includes a 4-axis driver box, connecting cables, a power supply, and three high-torque stepper motors. These motors, which share the NEMA #23 frame with standard stepper motors, offer significantly enhanced torque, exceeding standard models by over 75%.

To set up the system, users need to connect the 25-pin parallel cable from the driver box to their computer's printer port. The stepper motors are then attached to the mounts on the X, Y, and Z axes of the Sherline CNC-ready mill. Once the X, Y, and Z cables are connected from the driver box to the stepper motors, the system is ready for operation with the user's chosen control software. For those interested in expanding their milling capabilities, the kit allows for the addition of a 4th-axis rotary table, which can be integrated by connecting it to the designated axis A port.

This kit is ideal for users who prefer a customizable CNC milling setup, offering the flexibility to select and install their own software while benefiting from the robust performance of high-torque stepper motors. The inclusion of essential components such as the driver box and power supply ensures a seamless integration process, making it a practical choice for both hobbyists and professionals seeking a tailored CNC milling experience.
