hello mechanics
I would like to say that it is not possible to find the right materials and some design mistakes, but I am already working on version 2.0 as regards the mechanical part.

really cool.......

thanks I am improving the project as soon as the materials arrive should go much better.

Hey, can you give me a cnc reference?
Did you do this?

What kind of reference do you mean?
I did the electronic control part, and a small panel with a display and buttons to manage some mach3 functions without having to use a keyboard .

something from maker, but I made the various aluminum parts cut to a specialized company, and so I can have a good precision, certainly nothing professional and I can't work too hard materials but for the rest it's very good
 
I was starting to see something around, just to figure out whether it's a feasible thing or one of those things that after a while you realize you just spent money for nothing.

depend on what you want to do, I was interested a few years ago because I had seen it in university, I used it a period there and I became passionate then I have the passion of aeromodellism and for the construction of parts or entire planes is like having the magic wand.
Surely if you want to take a disapproval the Chinese that you find at 100/300€ are worth nothing are made with plastic components, and zero precision.
If you had to give me advice it is useful to make true what you think and drawings.

and let us see a photo and the suuuuuuu
Hi.
 
Hello everyone
Sorry I'm late but today was a busy day.
tomorrow I put some pictures to show you my cnc .
Sorry again for the delay in the answer .

Here I am with a new finished piece .is the lower ring with the wheels that will allow the wheel to flow better by reducing friction, I also modified the assembly of the motor that is now directly fixed on this ring and therefore I will have less holes and screws that I see externally.
 
first of all good, a nice object what you are doing and also cnc works well judging by the pieces that come out.
a question: . how do you guarantee the axial centering of the rotating part with internal toothing compared to the fixed base ? the ring with the bearings you have made (a kind of raddle ) surely keeps the vertical load well but cannot efficiently hold the rotor in axis, even if the bearings worked in a groove. probably there's something I didn't understand, but if the swivel tube crawls on the fixed you'll always have resistance to turn, amplified the push out of the stepper satellite gear. Perhaps you can add other bearings on the ring, equal to those you have inserted with the horizontal axes, but with the vertical axle, alternating with others. In this way you would land both the vertical load and the radial frictions.
ps the color of the pipes makes me think they come from the building... Am I wrong? ;)

I have created a first prototype using a top wooden ring that holds the mobile door that is fixed on the inner toothed wheel and therefore therefore keeps that in place, it works very well in the first specimen surely will not be the most elegant and technical solution but it works very well
yes it is a water drain pipe recovered from cutouts discarded by a plumber, has a diameter of 200 mm and is ideal for this my idea
