Z axis troubles
Well I finally got my z axis together, and thought I'd run it up and down with a 12 v battery. I ran it up and down a few times and then it jammed up. I took off the servo and pulled the lead screw and nut out. Once I got it into the vice I tryed to unscrew the rod and it was galled into the nut so bad I twisted off the screw.
So I made a new nut out of some different steel and ran a screw through it a few times with a cordless drill, then bang it also galled up! The original galled up with silicone grease on it, the second had some engine oil on it.
I'm using grade 5 3/8 16 allthread, and my block (nut) is 1" thich mild steel, with threads cut into it with a tap. The tap is good, and every thing works great... for a short while!
Will a grade 8 rod help, or will I have to upgrade to acme or a ballscrew?
On all equipment there are 2 levers...
Lever "A", and Lever F'in "B"
