Yea i'm fan of static table and CNC that i own now has static table and i'm really liking it.
Regarding my design now it has totally shifted over
Here is a design sketch that i'm working on now.
I decided that i will go with 1x1m work-space and welded base filled EG or polymerconcrete.
This will be heavy machine.
I'm planing to mill steel with it so it need to be rigid.
Main vertical columns are 150x150mm, all others 150x100mm 6mm thick.
Now i'm deciding on choosing linear rails and blocks.
I'm deciding between
BST motion - HIWIN ball bearing size 35 or 30mm
TBI motion - HIWIN roller bearnig size 25 or 30mm
Price is actually very close so i dont really know what to pick, bigger ball block or smaller roller blocks .
Also BST motion has good reputation, for TBI motion i'm not sure .
I'm going for at least medium pre-load if not high preload.
