A computer controlled (CNC) mill can turn digital 3D models into metal parts with ease. However, turnkey CNC mills are often too expensive for the garage DIYer who doesn’t plan to turn a large profit. Dr. D-Flo took the more affordable approach and converted a manual Precision Matthews mill (833T) to CNC by swapping in ball screws and stepper motors. While the mechanical portion of this video is specific to the 833T, the electronics and software can be used in any mill conversion or the creation of any large CNC machine for that matter. Learn how the Mesa7i76e controller board, LinuxCNC, and Probe Basic work together to translate user input and 3D models to real life movements of the mill. This addition to the Dr. D-Flo garage has acted as a catalyst for some awesome upcoming projects so get subscribed!
