Mini CNC ver 2 - part 1

thingiverse

Mini CNC v2 is a significant improvement over its predecessor, with the motor system driving the axes in a more complex manner. Gone are the whole elements with axles and limited slide lengths; instead, belts powered directly by motors take center stage, mimicking the design of high-end CNC machines. To support these belts and reduce friction, I've added rollers, thereby increasing the working area substantially - roughly four times larger than its predecessor's 4cm x 4cm space. This is a substantial difference, making it ideal for burning larger images. In fact, if you use longer rods, expanding the machine size to up to 20cm x 20cm is relatively straightforward, with only the base of the machine needing modification; all other components remain intact. Enjoy building your Mini CNC and share your creations! Having cleaned out my room, I found a treasure trove of materials that I repurposed to build this Mini CNC machine. Essential items for this project include: 1. Old bearings 8mm in diameter (with internal diameters of 3mm and motor axles also measuring 3mm) 2. Two DVD step motors 3. Plastic rolls from old printers or scanners 4. Steel rods approximately 100m long, with a diameter of 3mm 5. Two Easystep drivers or any other Step Motor driver 6. An Arduino Nano or Uno (whichever you have on hand) 7. A variety of cables and a thin belt from an old scanner Of course, you'll also need the 3D printed elements I designed specifically for this project.
