Hello,

I'm looking to upgrade the X (1000mm) and Y (600mm) axis lead screws on my hobby CNC.

Currently have a T8 lead screw. I put some preload on the nuts but still have some backlash. The T8 was ok at the beginning but I found a little bit small and fear that it'll wear fast.

I have looked two options 1/2 Acme 2TPI + anti backlash nut (CNCRP) or SFU1610 chinese ballscrew.

With shipping to Canada, both are around the same price

Normally the acme would be cheaper but with the anti backlash nut, bearing holder, shipping, customs, etc, the price goes up fast.

I know that the ballscrew would be better but I've heard some horror story with chinese vendor...

How the acme would compare to a chinese ballscrew? Any chinese vendor you guys know that are good?

Thanks
