The second run from yesterday with maximum tightening on the screws also showed a tilting of the build plate and resulting in a print shift. The angle is more or less the same ranging from 3-5 degrees off normal. Clearly tighter set screws is better but it was unavoidable to have up to 7 mils gap between the zeroing paper (150 micron) on one side. The level meter on the clamp arm is still showing 0.00 deg in both directions. The printed thick edge is around 7.25 mm and the other is around 6.6 mm. The small rectangle at the center also separated this time unlike the previous run. It's thickness ranged from about 4.7-5.1 mm.
This morning I disassembled the clamping head and cleaned /examined it. There is nothing obvious as to why the tightening of the right hand set screw causes the print plate to tilt.
Today I've zeroed on 120 um paper and still have a 0.004-0.006 inch gap on the left side. I'll see if that makes a difference although I really don't expect it to.
