Those models shown there are mine I spent some time before starting the design process looking at a few other 8020 type machines and took some ideas from them. The one thing i wanted to try and achieve that i havent been able to get any feedback from was the rotating nut. I havent found anyone that has tried this in a diy type machine. I have some of the parts made for that assembly, this week im hoping to get that finished.
Im starting to convince myself that i may need to get a second set of ball nuts and preload these axis. |
