well it's started, big time.
I bought my aluminium extrusion today just waiting wanting and more waiting for my stuff from china?? But now I will have to wait even longer for the extra ball screw and supports to come as I've decided to add a extra ball screw to stop it creeping as I have read on similar posts I may even up grade to stepper motors from 23 to 34's (but unsure at the moment)
I will post a image later when I have made my bed

Have you decided to get the next one from the same place?
I think for the size of your machine it's not neccecary. Remember that since the motor rotors are a greater diameter, their moment of inertia is much greater causing the feedrates / acceleration to be lower ... unless you use a higher voltage. For a size 34 to run effectively you would want higher voltage (mains) drivers. My machine is doubtless heavier, and I've settled with 10m/min rapid feed on the slowest axis - X. It's plenty...though I wouldn't say no to bigger motors!
