Re: [CAD_CAM_EDM_DRO] Bridgeport ballscrew backlash

.002 backlash is about the norm. its probably deflection moreso than slop in the ballscrew. Backlash comp of .002 breaks cutters? If the table jumps when it changes direction it is overcompensating.

I have a Bridgeport (was a Boss 5) that y'all helped me rebuild with
gecko drivers last fall. Thanks for all your help, its running
great even making a little money. I has about .002 backlash in the
ballscrews, both X and Y, and I was wondering if anybody know a good
place to have them rebuilt, or to buy replacements. It's not a
major issue, since my software (DeskCNC, which is a great program by
the way) compensates for it. But I have broken a few cutters when
the direction changes suddenly in a program. I've been told there
could be a way to adjust them, but nobody I know seems to know how.

Thanks in advance
Nate
