ELEGOO 36-20 Extruder Stepper Motor for Centauri Carbon

The round ELEGOO 36-20 extruder stepper: a 36 mm diameter can only 20 mm long, small enough to sit inside the Centauri Carbon toolhead. You buy one when under-extrusion won't go away after a nozzle clean — the feeder clicks, the filament gets chewed down to a groove, and walls come out with gaps and dips. Note the shape: this is not a square NEMA17, so a spare motor off a Neptune won't fit the bracket or the space.

Specifications

• Round can, 36 mm diameter and 20 mm long
• Four-wire lead with a JST connector
• Mounting tab for the stock toolhead bracket
• Genuine ELEGOO part, marked CC1

Compatibility: ELEGOO Centauri Carbon. Some sellers slip "Creality" into the title — that's a machine-translation slip, the part is ELEGOO's own. The listing doesn't cover the Centauri Carbon 2, so check for the CC1 marking on your motor before ordering.
