I used the upper-right and lower-left targets. After jogging the laser to the target, I used Get Position and the coordinate matched the machine display.
Framing the cut pattern showed the PnC alignment was off by about -25 mm on Y (toward the rear of the platform). Eyeballometrically, it looked as if PnC wasn’t turned on; next time I try this, I’ll put the fixture over on one side.
The second PnC alignment worked as it should:

Again, the Get Position coordinate matched, but this time the frame motion was correct.
