All credit goes to SilencedFrost, who has provided incredible add-ons for Neptune 4 printers. I just took this incredibel work and adapted it to my preferences.
This custom mount integrates the optical filament runout sensor by SilencedFrost directly into the SF 3x5015 fan shroud mod for the Neptune 4, and includes a built-in receiver for ECAS04 pneumatic fitting for secure Bowden tube connection.
It is thought to replace the stock runout sensor, which relies on a spring and bearings that create excessive resistance and can limit extrusion performance. By switching to an optical sensor, filament detection becomes frictionless—improving reliability and extrusion consistency.
⚠ Known limitation: Optical sensors can’t detect clear (transparent) filaments, so filament runout may not be detected when printing with transparent materials.
Features:
ultra-compact, integrated mounting solution
Built-in receiver for ECAS04 fitting for Bowden tube
Eliminates mechanical resistance of stock sensor
Improves extrusion performance and reliability
Compatible with SF 3x5015 fan mod for Neptune 4
