Whether or not you’re actually going to build this CNC wire bender, we think you’ll love getting a closer look at how it’s put together. The team over at PENSA got such a strong reaction from a look at the original device that they chose to film a video (embedded after the break) showing how the thing was put together. They’ve also posted a repository with code, bom, etc.
In the image above [Marco] shows off the portion that actually does the bending. It’s developed to mount on the pipe through which the corrected wire is fed. The 3d printed mounting bracket really makes this a lot easier. The assembly offers a place to attach the solenoid which moves a bearing in and out of position. That bearing presses against the wire to do the bending, but should be moved from one side of the wire to the other depending on the direction of the next bend. This is a lot simpler to understand after enjoying the demo video which is also embedded after the break.
