Since I’ve invested a significant amount of time investigating this issue, I’d like to share it with others to save them time.
I’ve installed an AMS Riser on top of the H2D. This riser features a strip of LEDs that illuminate the “build plate.” It appears that the luminance or warmth of the emitted light on the build plate is causing the “High Precision Nozzle Offset Calibration” to fail.
Whenever I have the Riser LED enabled, the “High Precision Nozzle Offset Calibration” fails, even though the visual appearance of the calibration lines and color contrast is satisfactory. I’ve conducted multiple experiments with the same configuration, and the only consistent factor that affects the outcome is the status of the Riser LED. I have to add that this effect is only observed in "High Precision Nozzle Calibration.
