Dave here. I'm designing a new machine for the office in the hopes of carving precision rifle stocks (4 axis) and whatever else is required from hardwood and aluminium. :)
The build is already underway and frame currently ready to be painted.
Details of the build
Linear bearings: SBR20 fully supported rails - X:1300mm - Y:1000mm - Z:450mm
Ball screws: RM2005 Chinese - X:1350mm - Y:1050mm - Z:500mm
Steppers: Nema23 - 23HS45-4204S
PSU: 48V 600w DC
Frame/Chassis: 65x65x3mm box steel
X axis chassis: 75x75x4mm box steel
Gantry cross beam: 200x100x5mm box steel
Gantry supports: 300x125x10mm steel angle
Z axis supports: 200x480x10mm steel plate
Contrary to most builds on here I do not have a CAD diagram to show as the build is a running design at present. I have very little CAD skills unlike my wife, who regularly makes designs in Solidworks.
Here's some pics of the current build:
Front on view - all level within ~1mm
Z axis setup.
Gantry side on.
Anyway, thought i'd share guys. let me know what you think. :)

Looking good so far Dave.
Any reason for the 2005 ballscrews? The 1605/1610 are more popular because they have lower inertia which helps with the acceleration and deceleration, especially on the modest 48V you are using.
If you want a decent machine you have to have decent electronics...Clive
Good luck with the build...Clive
You can run both X axis screws with one motor and belt connecting them,it's common practice with the guys on the forum.
You can get custom belts but they are more expensive, but you have a lot of leeway length wise as you will have adjustment on the motor and your tension/routing belt layout. there was a post on the forum a while ago showing a belt routing setup to address this issue.
