Make a badass CNC mill


Ben Heck and I got into converting a mill to be a CNC machine during our podcast interview. Today I found a pair of great write ups at balbots on modding the Harbor Freight mini mill that I mentioned. Part 1 get into all the details of converting the mill to use stepper motors, and adding a cooling system. Part 2 covers upgrading to DC servo motors and replacing the gears with a belt drive system.
