(have no idea how to read those report's)
The machine was started from a cold start.
The mill was homed prior to the tests.
The measurements were taken with a Haimer 3D probe mounted in the spindle.
The Haimer probe was calibrated for concentricity in the mill spindle prior to the tests.

These tests were air cuts using dedicated test nc programs produced by Fusion 360 and the standard Centroid mill post processor.
The purpose of these tests were to test the amount of X, Y, and Z cumulative error stackup.
The measurements were taken via a Hiamer 3D probe against surfaces of the vice which was attached to the table's fixture plate.

Three test programs were used: v8, v9, and v10.
Each program had more steps on the X & Y and then the X, Y, and Z axes.
The v8 program is a single pass, single cut.
The v9 program adds seven steps down in Z.
The v10 program has seven steps down in Z and six steps in on X and Y.

The cumulative error amounts from the air cuts were significant.
The v10 test yielded 1.02mm error in X, 0.83mm error in Y, and 0.06mm error in Z.
On a pass/fail basis, I considered these results a fail.
