As an exercise to hon my machining skills and to fill a gap in my 3D printer farm I decided to machine all the parts for a new 3D printer out of aluminium. It has been very rewarding and I learned a lot, I'm confident now that I can set up a job for any part I want.

The plans for the 3D printed CNC that I used to machine all the parts can be found here:

And the videos where I make it are here:

The Z axis motor brackets were the first ones I tried and it shows, very bad cuts but useful parts. I was using a thicker plate and different alloy and that gave me a few headaches.

I started the build with the intention of using an SKR 1.4 turbo electronics, and you can see that I even installed it on the printer but once I got to the point of modifying the firmware I saw that it was going to take another month alone to learn how to do it properly so I went and grabbed a ramps 1.4 that I had lying around as I can configure those in a breeze. As a result I had to remove one of the Z axis switches but it all worked well in the end so I'll keep the ramps in there.

I had to make a few changes along the way like the X axis belt tensioner but I couldn't show all of them or this video would have been 3 days long.

I hope you enjoy the video as much as I did enjoy making it!!
