I´m trying to install my fourth axis, but it seems to have serious backlash. I can even rotate the frontpart a bit with my hands, where the chuck is attached.
On the webpage they say, there are screws for eliminating the backlash, but I can´t find the right ones...Did anybody adjust these anti-backlash screws so far?
thanks in advance
Have you seen this: http://www.sherline.com/3700inst.htm ?
See the section on Maintenance at the bottom, just before the diagram. Hopefully that will get you going. It isn't terribly well explained.
