Nice machine Dean - have you made one before ? :)

Out of interest do the profile rails down the side also bolt horizontally into the steel sections or just on the support brackets?
Would the ballscrew be drilled and tapped in the ends to bolt through the supports ears? Or the supplier may prefer to machine external threads and use a nut to tension.

Mark, as you are starting out then study this machine as it contains lots of nice features that would be missed be the casual observer. At all the critical interfaces there is scope for alignment and adjustment so you can dial it in.

No not made one using this technique because I've got large Granite surface table so use different methods to get surfaces on the same plane. Mainly to save costs because the profile is expensive compared to steel.
However, I know from experience using lots of profile this technique will work great and would certainly use it my self if needed.

The Model shown is just basic layout to give some idea of the concept and that all fit together without any hidden surprises. (Which if got keen eye will see this model does have one in gantry area which would be pain unless corrected.?)
The original design was actually setup to be R&P but also did Configuration for ballscrews which shown.

When I actually build then I model to the last detail and actually use dimensions for cutting list etc.
This way I know 100% there will be no hidden surprises or costly cock up's. Only need to be off few mm's in some key areas and can cause your whole world of pain or worse still compromise the machine.

The plan was they would bolt in both directions. This would allow more setup adjustment.
The ball screw would be threaded on the ends so can put tension on them. The brackets allow adjustment for alignment.

Adjustment is Key at the DIY level and the more you build in the easier and quicker you'll dial in the machine. Unless you have large Gantry Mill to machine surfaces flat, parallel etc then the only way to achieve accuracy is with adjustment and lots of patience tweaking as you go.

Here's another simpler to make design. Warn thou it's heavy. Those lower beams are 300x200x6.
