How to Convert a Manual Mill to CNC

Learn how to convert a manual Precision Matthews mill (833T) to a computer-controlled (CNC) machine in this comprehensive 27-minute video tutorial. Discover the process of upgrading from lead screws to ball screws, and installing stepper motors for precise control. Follow along as the instructor demonstrates disassembly, conversion of Z, Y, and X axes, and reassembly techniques. Gain insights into dovetail ways, hand-scraped ways, and the importance of tramming. Explore the electronics setup, including the Mesa7i76e controller board, and understand how LinuxCNC and Probe Basic software work together to translate 3D models into real-life mill movements. Conclude with test cuts to verify the successful conversion, equipping you with the knowledge to create your own affordable CNC mill for DIY projects.
