I recieved an email with a similar story: $650 to refit a Bridgeport with
ball screws from a company called HiWin Technologies.

Was it $650 for just the screws or the screws with the ball nuts? ( I'd bet
it was screws with nuts but I just want to make sure.)

Were they called "preloaded"? That seems to be common with the zero backlash
setups I've seen. You said that zero backlash is a must so I assume yours
are.

If the Ah-ha software can compensate then I am happy with 0.003 in/ft lead
accuracy.

I am glad to hear that ballscrews and nuts don't have to cost more than my
machine did.

I will call them tomorrow and inquire.

Thank you,
