Do you have a cable chain? If not i highly recommend the Russian ARKO 22x80 R60 which is cheaper and better than the similar Chinese
Awesome, those are good prices, I need to see how much shipping is going to be but that was good timing cause I have not purchased chain yet.

Jazz, thanks for the video exactly what I was looking for in a review. Time to order some motors and drives... I emailed to see if I could get a price for motor/drive and 7m cable set.

So the resolver feedback into Mach is awesome, shows how new I am to this I didnt even know that was possible. Anyone know if the smooth stepper from warp9 can do this? It shows resolver connections on the board but does it send back to mach? Also looking at the CS lab boards as well since Jazz has a good review on them. Im thinking I might go for a servo for Z as well since that can give me position feedback into Mach rather cool feature.

Gerry, I had started a build log over at CNC Zone but after finding the great information here I decided to put my build log here instead. Also for me the cnc zone website is painfully slow!

Currently using the rotating ballscrew design to design one that I can build with the machines I have. Might be a little crude, also sending out designs to some local cnc metal shops for quotes on parts. One question, (of many im sure) do you guys find you need to grease the ballnut more since it is sometimes spinning rather fast?

Thanks for all the help, I will post some design ideas shortly for the rotating ballnut.
