This is really not much of a thingy, but it saved my sanity!!!
You see, I got this great RepRap I3 style 3D Printer: Aurora A3. And it is pretty sweet. Built like a tank, runs smooth and pretty quiet....except this Dam rattle!!
It was driving me crazy!!!
The two Z-Axis screws are just barely long enough to reach the aluminum top brackets. And those holes in the brackets are 9mm while the screw rods are 8mm. So while the print head moves back and forth on the X-Axis (or even the fans on the head spin) it creates vibrations that amplify up into those aluminum brackets and down into the sheet-metal frame.
It's a grinding vibrating racket!!! AAAAAAAAAAAAAAAAAAHHHHHHHHHHHHHHHHHH!!!!
Well, slow me, I finally noticed little holes in the center-top of the Z-Axis screws and thought "I bet if I made a bushing with a pin in the middle it would hold that screw centered in the hole and not vibrate against the side" Duh!
Cause it did!
Now I can print all day without wanting to Van Gogh my ears!!!
If you have an Aurora A3, you probably know what I'm talking about.
Hopefully this will save your sanity as well...
