3D Printer Part 3: Attaching stepper motors

In this post I attempt to describe how I attach the stepper motors on the X and Y axis, and how I’ve started mounting the lead screw for the X-axis.

For this post to make any sense at all, I will have to show how the X-Y table works (10 second video):

So the job here was mostly to attach the motors to the X-Y table somehow, and then attach the lead screws, bearings etc afterwards. Having a look at the X-Y table, there are already one ~15mm hole with set screws for each axis. Since the stepper motors won’t fit in these holes directly, I created a couple of adapters by turning aluminium.
