Cnc4u have 2500mm x 20mm screws which I was wondering about using although I do also have enough mod 1.5 rack here that needs a home or selling.

were about's are you?

Im In Hebburn, Tyne & Wear.

Ive just changed the pinions over on the drives to mod 1 pinions so not really any use to me pal.

I thought you had used those drives on another build? The rack and pinnion does seam nice on my build I have done but I was thinking that screws would be the way to go posable. if you have the drives already though then your half way there.

Yeah they are on the 4x4,it was a 3mtr but had to cut it down due to a large contract coming in and needed the space. ive now sorted the shop so that it would not get in the way

OK ive managed to get a little more done this morning before the wife started chewing my ear.

Fingers crossed if all pans out, i can have the frame uilt for friday and into powdercoat for saturday/Monday.

Im thinking about servos on the X & Y and a leadshine on the Z. any suggestions?

Best advice with regard to Z axis is to put rails on front plate, bit where the spindle mounts, and bearing blocks on back plate, i.e. opposite to what you've shown.
