Fancy making yourself your very own Arduino-powered DIY wire bending machine? With a few extra parts, like stepper motors and some 3D printed parts, you can do just that with this great tutorial. Thin Mdf

Before you start, you will need to get your hands on some basic components. We have included links to the products in case you need to buy them: 

This great little wire bending machine can turn basic brass wire into some interesting; geometric shapes like a triangle, square, rectangle, hexagon, and even a spiral!

Of course, you can also experiment with the parameters to create any shape, within reason, you like from the serial monitor. The project is fun to build on your own, but will also go perfect as a classroom project too.

The first part is to wire everything up. Here is the circuit diagram: 

You can either solder the components to a PCB board or connect up using a breadboard. The choice is yours. 

Next, you will need to 3D print some additional parts. You can check out the 3D print files here. If you don't have access to a 3D printer yourself, why not ask a friend to help you out?

The parts will need to be printed in PLA at 0.15 layer height with 80% infill. 

Once in hand, you will then need to begin assembling the parts. Use the bolts and nuts to affix the 3D parts to the MDF board, as well as, mounting bearings and stepper motors to their respective positions; as shown in the video.

You will also need to mount a 3D printer filament feeder to feed the brass wire into the machine from the ball bearing straightner assembly.

With all the parts assembled, it is time to sort out another critical component -- the actual code for the Arduino. We have included it in full below, but if you want an explanation of its various parts, see here. 

Boatbuilding With Plywood Now just upload the code to the Arduino, connect the power, and get wire-bending at your leisure using the serial monitor. Enjoy!
