RE: [CAD_CAM_EDM_DRO] Re: ball screw conversion

I already have single-ended 42 frame motors attached by toothed belts
and pulleys.

The link http://www.homeshopcncn.com does not appear to be valid.

http://www.homeshopcn.com is something else entirely.

It seems odd that I've been able to find a company that makes it easy
for amateurs to do this conversion. Maybe it's less commonly done
than I imagine.
