Actually I did a similar thing yesterday max. I was jogging my Y to the point that the ballscrew came out of the nut. I said the hell with it and cleaned up a little.
The cause of it? My laptop has that menu button (to the right of the windows key) very close to the arrow keys. While I was pressing and holding the key my big finger also pressed the menu button. Since I wasn't looking at mach I didn't catch it in time and that was that.
Now I have a reason to machine me out some mounts and get my limit switches working. I spent about an hour today putting the bearings back in the ballnuts and got everything back together. I noticed that there's a gap between the bearings if you look for it. Looks like another bearing could fit in there but its not big enough. I counted them when putting them back in. Maybe this is the cause of the backlash. |
