1st Build, Second machine

sorry I put a extra 0 in my post even so I would buy supported rails or even bearings on a length of steel like the FA100 Machine I think that's the right machine if cost is a issue

worth a look Michael

Michael knowing the tolerences you want to work too then even at this length the unsupported rails will make that nigh on impossible.

With a machine this small the little extra cost for frame material and supported rails would be worth every penny.!!. . . . Dont dont it mate.!

I'd forgotten the required tolerances were very very tight ... so I couldn't agree more.

You've gone for profile rails on Y/Z, which couldn't be better, then used the worst option (disregarding silly things like aluminium angle+bearings) for X which is the main support.
Just make the bed a little wider and you can fit some nice profile/supported rails underneath with the added bonus of them not getting covered in swarf.
