Thanks for the replies.


I didn't realise Chinese supported rail was so cheap....


As for the drive, what are your thoughts on using a mod 1 Rack and Pinion instead of Ballscrew (as its less fiddly) and just using the ballscrew on the Z?

Also if the rails come in Aluminium, what do you think about brazing them onto an Aluminiuim Frame.

I quiet adapt at it now... unlike when I started (its a lot harder than you think to braze aluminium).
