Rotating Ballnut - design ideas

[JAZZCNC]

The only option is to do it right.
Why to invent the hot water again when it was explained here in the forum hundred times how to do it properly. Ball screw prices from China are very good price and if you are making a big machine means you will make money from it. Hobby or not.

The example machines with the rotating ball nut you linked were made from people that have Zero understanding of Inertia, Acceleration, Snappines and so on.

People giving you advice here have though and forgotten already what you still don't even know about CNC.


Nothing personal against you but i am seeing a tendency here in the forum. People with Zero knowledge come here ask questions, dont listen to the answers and try to promote their own truth. And waste their and our own time. I have not answered in detail at least in 20 questions lately cause i see people will not listen or do what i am saying so why waste my breath.

I am saying it again in other words: Do something that is proven that works well, don't fancy yourself an engineer, cause if you were, you wouldn't be asking questions, or if you were -you would be listening to the answers. So you will finish with successful build and will be extremely happy to have listened to my friendly advice.

No sorry Boyan that's not the correct attitude. I do understand your frustration and what your saying and won't lie I've felt the same before many times but If I had done that or Jonathan etc who helped you all those years ago then you would have a very different machine now or possibly not at all because you might have given up.!!

We all have our own way of learning and building, just because it works for you doesn't mean it works for others or your design suits or is better than the other.

You can not and should not say this design or your design is the only way it should be done, likewise, you can not criticize anyone who doesn't take the same path you did. We each make our own minds up based on our own requirements and you shouldn't try to force one plan onto anyone else.

Give them the benefit of your experience because that's the correct thing to do so we all learn together, but pushing YOUR WAY is the ONLY way is just wrong.

End of the day I see it that we just give our advice based on our experiences and it's down to the reader to act on it or not.
I've done this 1000's of times knowing the one asking the questions isn't listening or thinking they know better but yet I still do it because I know there will be 10 or 100 others in the background watching and listening who will take notice. This is also why I ALWAYS challenge BULLSHIT when i see it and will argue until my last breath when I know it to be wrong or Bad info.
Often I can turn them around and get them to see what I'm saying makes sense and is in there interest to follow, those that don't then good luck to them and if they come back and prove me wrong then that's good as well, because I learn from them. The Circle of CNC Life goes on and evolves...Lol

Just Chill mate and take another drink.!!. . . . . Just know we help more people than we realize or see, the Idiots who won't listen will always be idiots who can't be helped no matter what we say.
