Thanks everyone for feedback and sugestions.

Latest design, incorperating longer bed so 1200 x 600 cutting area on bed, RM2020 x 1400mm with BK15 fixed bearings each end on X axis with belt pulley arrangement for one motor operation. More bracing added. Stil not decided on fix or movable bed yet.

Lots more to do to design, covers, cables, screws etc. But I have produced a bill of materials which I have started filling in.

I've done a sort of trafic light system so you can see were I'm short of advice and knowledge. I will search the forum for answers, but probably end up posting more questions here.
