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.
Lucky me who has access to this machine!
Started with a massive cylinder of aluminium. Turning one end to be smaller and smaller
Almost done turning!
Copying holes from one piece to the other. The bore is used to align them perfectly on top of each other.
Two finished adapters, one for each axis. This piece fits the stepper motor on the back side and X-Y table on the top. The four screw holes fits in the motor. The thin end fits into the hole of the X-Y table. The rotating shaft of the stepper motor will come out of the hole in the middle.
There it goes
The adapter now fits on the stepper motor
The adapter and stepper motor now fits in the X-Y table
This is how the lead screw is mounted to the X-axis. I had to create the aluminium piece to fit the existing screw holes. I bought the lead screw and nut, and had to make some adjustments to them.
This is the aluminium piece, ready with a hole for the nut
