AMS 2 PRO Filament Feed Fix! Hub Spring Issue!

Bambu Lab AMS 2 PRO Spring Fix (X2D Combo Hub Repair)

Is your brand new X2D Combo throwing constant AMS feed errors because the filament won’t load? If you can't print because of filament blocked, this is the reliable fix.

This model is designed as a secure, tool-less solution that overcomes the inconsistencies filament fix. Keep your printer running with minimum downtime.
 

🛑 The Problem

The factory spring mechanism on the new AMS 2 PRO is too strong, causing the filament routing mechanism to block loading. Many users have tried simply pushing filament into the space but this pops out eventually due to the smooth edges especially during high-speed printing or rapid retractions, causing feed errors and stalled prints.

 

✅ The Solution

I’ve designed a custom, geometry-aware insert that stays in the slot! Providing a consistent, secure hold to prevent the faulty spring entirely. Easy to install and easy to remove once your replacement hub arrives.
