Rotating Ballnut - design ideas

Hi Jonathan,

really nice design on these- they still working a treat?

i came across these badgers http://www.drives.co.uk/fullstory.asp?id=3388- but as i say on my little build log thing- bet they're bleedy expensive-!

i'm tossing up rack and pinion vs this type affair for my long axis- (2.5m) so lurking about tying to decide to my way forward!

Thanks... yes they're still working very well indeed. Same performance as in my post a month ago. I wouldn't hesitate to use them instead of rack and pinion on a 2.5m axis. You'll get better accuracy, longevity and it'll work out cheaper. With a RM2510 (or even a higher lead) the machine will be plenty fast enough with good acceleration.

They do look good, but as you say they wont be cheap.

that would indeed be interesting Jonathan- do you want to work it out and PM me- or post it's up to you-!

i'll work out the mounting of them- i was thinking of tucking them out the way under the x rails- so to minimise dust/ crap getting onto them-

thanks again
