Extruder Extension Cable Assembly for ELEGOO Neptune 4 Series

A ready-made harness that ties the print head to the mainboard: heater power, thermistor signal, two fans, the LED and the sensor line. Every connector is factory-crimped and labelled, so you can put the head back together without ringing out a single wire. Most people buy one after a conductor breaks inside the cable chain — that is the usual cause of intermittent thermistor errors and prints that stop for no reason.

Specifications

• Labelled connectors: FAN1, FAN2, LED1, PS, PAC and the heater line
• Flat ribbon plus power leads under one braided sleeve
• USB-C connector on the print head end
• Five length and content options across the series

Compatibility: ELEGOO Neptune 4, Neptune 4 Pro, Neptune 4 Plus and Neptune 4 Max. Harness length differs between models, so pick the option that matches your printer.
