I’ve almost got my machine perfectly balanced, but I’m having one last tweak I just can’t figure out. I’ve leveled my z axis from one side to the other (from one side of the table to the other), but I have a 1mm difference between the height of the steel tubes as measured from the same side of the table.
Put another way, when I put a wood block on the table and lower my z axis, one tube touches the block before the other.
It used to be worse, but I found that one of my wheel rollers was a little too loose and sagging. Now they are all firm, but still I have a 1mm difference which seems to cause a tiny lean in my bit when cutting. Any ideas what else I can check?
