Hi,
I could have done that but a bit meh with the fuss involved.

I think I will mount it with bearings moving with spindle. It just makes everything a lot easier. I'll take into account the lost rigidity of spindle mount without the rails. 20mm thick aluminium seems to be the standard isn't it? I think it should suffice. And yes having some hywin type rails would be nice but the ballscrew is the limiting factor at the moment as I can't machine into the aluminium so their profile could be lowered. Hmm maybe a project after this is complete is to make a new z axis with hywin rail.

The table is bolted to the ground in 8 spot(one each leg) so I'm guessing this might mean I don't need triangulation?? Will wait and see. The epoxy leveling was done after. This means that I can never move the machine(as it would have twisted when I bolted it down), at least without redoing the epoxy each time.
