I would guess an initial accuracy over the whole work envelope of
.1" at
best, as I'm
sure they do the minimal amount of calibration. They probably use a
square to
set the orthogonality of the axes, and that is ALL.
One would expect a final test to be a pen plotter.
a large square drawn, then rotated 90 deg, would show squareness
pretty well.
But, As you implied, alignment at the factory only needs to be
superficial. the breaking down, then boxing and reassembly would be
well past any factory calibration.
I wonder how much the sell for ?
