+1. I would also be surprised if they are custom made items rather than off the shelf. They are well engineered.

The picture in a previous link shows the FGR ball nut on a standard Stepcraft ball screw, so I think that makes it almost certain that it's a standard item. Perhaps there is someone in the know who can confirm that.

Could you post a link to the specific ones you got? The Moore site gave you the choice of sealed or unsealed, wasn't sure which one to try, what did you choose?

Thats great news, fingers crossed.

The stepcraft screw, is not designed to have balls in it, so you gonna have to fork out ~200 pounds for a set of 3 custom ballscrews, and then do some DIY to get them mounted
I can post pics of our one, once we have all the bits

I could swallow a couple of hundred pounds for a significant upgrade to improve backlash and longevity.
peterg1000 schrieb: Incidentally, could you please let me know the shank size of the old nut - I've guessed at 10mm to take the M6 screw.

I was at an Engineering Exhibition today and learned that CNC4YOU are integrating a wireless control pendant into UCCNC (V1.3xxx?). It will be available in a few weeks once the final bugs are ironed out and testing is completed - so they say.
