EMMC Module with Pre-installed Firmware
The Neptune 4 series stores Z-offset data in the Klipper configuration on this module. Drifting often results from a mismatch between the MCU and the handheld screen's saved variables, or an EMMC read/write error that prevents the 'SAVE_CONFIG' command from persisting after a power cycle. Replacing the module ensures a clean, synchronized logic state for the coordinate system.

Inductive Proximity Sensor (Z-Probe)
This sensor detects the metal build plate using an electromagnetic field. Internal thermal sensitivity in the probe's coil causes the trigger distance to change as the print head warms up (heat soak), resulting in the nozzle being too high or too low at the start of a print compared to the calibration state.

Silicone Bed Leveling Columns
Physical 'drift' is frequently caused by the stock bed springs losing tension due to the high-acceleration movements of the Neptune 4 Plus. Replacing the springs with solid silicone columns eliminates mechanical movement of the bed platform, ensuring the distance between the nozzle and the probe remain constant across long print durations.
