I've got a CNC/Arduino-like project, for making a photograph of a magnetic field through a plane. It is done by means of a coil: everyone says that's a fake, but that's for real :).
Here are images of the motherboard from my prototype: you can see EMI from CPU coils, RAM, and FAN noise:

First time I've used a printer-based setup, but it lacks required precision - my X-axis (the printer head) moved too fast, and not in a predictable manner. It exposed jerky sensor motion, due to a plastic belting drive, unsuited for low speed operation:

Now, to upgrade this CNC project, I want to connect motors to the head, in a better, much more precise way. Instead of plastic belting I want to use a threaded shaft drive (like a long threaded screw). The head I want to use must be like this:

enter image description here

I need to connect the round motor shaft to a threaded shaft, for rotational movement. And the problem is that I have a motor with a totally round shaft:

The high speed DC Motor that I am using is 12V, its shaft diameter is 2.4mm. My question is: How do I attach this shaft to a threaded drive?
