CR10 V3 bed leveling
I checked the table and it is flat.
I level out the 4 corners getting a slight rub on the paper in each; however the center of the table is low - no rubbing of the paper anywhere across the X axis. The paper measures 0.10mm. If I fold it (to double the thickness) over I get a heavier rub in the center telling me the center of the table is about 0.10mm lower than the corners. I confirmed with feeler gages where a 0.1mm feeler has a slight rub in the corners and a 0.18mm feeler has a slight rub in the center.
Might it be that the Y axis guideway has a bow in it of about 0.08mm?
