800x800mm CNC router build / upgrade questions & hopefully build log

I haven't really got the time to read all of the post so just quickly flicked through the images but I can see straight away that you are going to run into trouble with alignment and setup because you haven't got any adjustment so even with a machine to help you make parts you won't make them so accurate that you won't need some way to make adjustments.

The golden rule of DIY building is to allow for Adjustment, then a little more adjustment for good measure.

Thanks,

Where would you suggest adding the room for adjustments?

I've got some adjustment laterally on the linear rails on the extrusions, how much wiggle room should I be looking for?

Is that a reason for using the BK style ballscrew mounts bolted to the axis instead of the FK in the endplates?
