Issues to be resolved:
1. Do I want an adjustable bed ? - Pros and cons?
2. Overhang at end of machine? - Right, Wrong, Better suggestions?
3. Motors, what size?
4. Can I put off doing electrics/computer side of thing until I have finalised design?

Looks like you have done your homwork
1) My machine is quite similar to yours with an adjustable bed. But I have never had any occasion to alter it, I you do alter it you have to get it level again and resurface.

2)That to me seems OK.

3) Nema 23 all round with low inductance and decent drives (AM882 or EM806) are good BUT think about moving them to the back of the machine and (if I had my time again) change the X to 1 x nema 34 and use long belt for the two screws. This give you a better choice of motion controllers and less problems with homing etc.

4) I would not buy or start any of the electric stuff until the main frame is built as things change over time.

Good luck with the build.

I will have a redesign based on your comments, stick with fix bolted bed that could be movable in the future to cover all options.

I have about 4 positions that I can mount my bed in (bolted) But never need to move it. machine 1600 x 1000
