There are a few conversions around that are decent. Lots of different ways to get the machine going.
I've started a site dedicated to cnc of the mini lathe: 7xCNC.com
I've stated to document my bills, plus there are links to some others. I just got my cad to cam to LinuxCNC sorted on the weekend so I can now make complex curved parts.
I've started some simple guides on some software stuff too.
I plan to put up some more photos and info in a couple of weeks (away for work at present).
Hope that helps.
