Down to less than measurable. Kind of weird…I feel by fingers not flat but the vise sticks to it. Must be close enough. Definitely not going to worry about a small corner I’m not going to use.
You may be feeling the feed lines if you’re unable to measure any error across the table.
Judging by the first picture you posted it looks like your nod and tram are pretty decent also. If your vise is sitting flat enough to create stiction with or without coolant you’re probably in good shape.
Let the chips fly!
