Have you a read through this build log? Lots of renderings at the start and photos of the frame later on that might help.

hi clive, what do you mean have factored in the whip?
cheers
Ball screws have a critical speed that you can reach before they start to whip I am not an expert on this but I would have thought that if you are using screws that long you might need rotating ball nuts. Do a search on here there has been plenty of talk about it.
i used rotating nuts, on my 8x4 build because of the whip effect Clive mentions.

thanks guys i will take a look :)
i want to hide my z axis stepper motor rather then having it stuck in the air so it requires a belt and pulley, is there a requirement to which i should aim for? more teeth the better or the opposite?
cheers

i recommend to brace the legs with the diagonals , not the way it is now, there is no force pushing on the braces on that orientation
:)
think this maybe my final design on the frame, what do you think?
cheers

I would suggest you don't need the flat bar as it's not likely to add anything, where you've got the angled sections on the "feet/legs" of the frame, move those up into the rectangular spaces or add some there, they will serve you much better.
