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.
