Mini CNC Milling Machine -3

by John

3 Sessions of 3D printing and the PLA printed parts are made. The first session was 5 hours, the second session was 15 hours overnight, and the third session was 8 hours. 28 hours altogether. And all of the parts look excellent and have a very solid feel.

The first session. None higher than 10mm. 5 hours.
The second, 15 hour session. 500g of filament. No rejects.
All of the remaining parts were printed in the third session, then a few hours removing supports and bolting parts together. Here the printed components sit together, to display the basic size and shape.

Now I have to wait, impatiently, for bearings, stepper motors, trapezoidal threads and nuts, and other hardware to arrive by post.

Maybe I will make a start on the electronics enclosure meanwhile.

Here is a photo of Stuart’s mini mill electronics box, which contains the breakout board, 4 stepper motor controllers, a power supply, etc etc. He certainly exhibits a standard for the rest of us to try to achieve. I will just copy what he has done. That box of tricks should be useful for any other CNC machines which I might make.
