ELEGOO Neptune 4 Max Y Axis Motor – Original OEM Bed Motion Replacement

Designed for Large-Format Bed Movement

The ELEGOO Neptune 4 Max Y Axis Motor is a genuine OEM stepper motor engineered specifically for the Neptune 4 Max 3D printer. As a large-format printer, the Neptune 4 Max requires stable and precise Y-axis bed movement to maintain dimensional accuracy across its extended build area.

The ELEGOO Neptune 4 Max Y Axis Motor controls the forward and backward motion of the heated print bed. Smooth Y-axis motion ensures consistent layer stacking, reduced vibration, and improved surface finish during long prints.

If your printer shows bed skipping, vibration, unusual movement noise, or layer shifting, replacing the ELEGOO Neptune 4 Max Y Axis Motor restores factory-level motion precision.
