Advantages of using my plans: 1. A machine modified according to these plans will have complete 3 axis CNC capability while retaining full use of all 3 axis manual function. 2. Z axis lead screw is located out of the way of the milling work area above the mill head away from chips and dirt. 3. Plenty of room around the stepper motors allow use of nema 23 or the larger nema 34 frame steppers. 4. No major disassembly of mill is required during the addition of the CNC hardware which makes the conversion quick and easy. 5. The only permanent change to the Mini-Mill required for the conversion is the addition of two tapped holes added to the mill head. 6. All machined parts can be made right on your Mini-Mill prior to its conversion to CNC. 7. Cost of required aluminum stock, lead screw and other hardware will be between $160 and $300 depending on the type of lead screw and motor size selected by the builder. |
