Step 1
Disable (uncheck) current squareness correction as shown.
Step 2
Place the bar-ball on the XY plane of the CMM at angle 45 degrees to the X axis.
Step 3
Measure the length of the bar-ball.
Step 4
Place the bar-ball on the XY plane of the CMM at angle 135 degrees to the X
axis.
Step 5
Measure the length of the bar-ball.

Compare the two measurement results. Results that vary significantly indicate
the axes are out square.
