Auto Leveling & the Dual-Zone Bed

Auto leveling

The Neptune 4 Pro measures the bed in a 121-point mesh. Run it with the bed at printing temperature, then save the mesh — Klipper only keeps it after a save.

Dual-zone heating

The bed has an inner and an outer heating zone. Small prints only need the inner zone, which saves power and heats faster. Turn on the outer zone for prints that cover most of the bed, and level with both zones on.

Z-offset

Fine-tune in 0.02 mm steps during the first layer, then save it from the screen or with SAVE_CONFIG in the web console.
