Description

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.

Boost Me (for free)

Boost me for Free!!! Thanks I will continue to make wonderful designs and check out my other projects. If I get 10 boosts I will upload manual 3 X 1 filament track switch using ptfe couplers.

Key Features:

Strong Design: Dual prongs ensure the block stays exactly where you put it, preventing it from popping out under pressure.
Easy to Use: Tool-less installation. It slides into place and pulls right out when needed.
Two Versions Included:
- Standard Version: Features a recessed top, making it easier to grip, insert, and remove.
- Micro Version: A low-profile, smaller option if you need extra clearance or prefer a very clean, hidden look.

🖨️ Recommended Print Settings

Material: PETG, ABS, or ASA recommended for temperature resistance and slight flexibility. PLA+ will work fine temporarily.
Layer Height: 0.16mm or 0.20mm
Infill: 25% - 100% (Solid printing adds durability to the prongs).
Walls: 3-4

🔧 Installation

Unload one or both of the middle filament from the AMS 2 PRO.
Press down on the tension button.
Align and push the printed part into the gap above the button, ensuring the two small prongs point down into the slot. Pressing firmly till into place until it seats flush.
1. Print with confidence!

THANK YOU!! I have been struggling with slots 3 and 4 not loading in my brand new AMS 2 Pro. I sat by the machine pushing the spring down manually every filament change for about an hour just to finish a print. plugged this guy in and no more issues! Not all heros wear capes.

@hholderness

wow thanks so much for the boost! this means a lot and glad you are back to enjoying printing. love seeing some of those multicolor prints. This should be the last you see of this issue.

@NicoRau_

I assume that "motor conveyor unit blocked" is meant. First, slot 3 did not work, then recently slot 4 did not work. Even though the PTFE tubes are free and nothing is clogged. I have checked carefully

Replying to @Skully23 :

Open a ticket with Support for problems with new X2D/Combo AMS2 units. They replaced my AMS2 internal hub with little questioning.

@2409mile

Because you just can't get to the bottom of it. No more understanding of technology. It's the hub. New in for warranty and done

I don’t understand how or why this has worked for me. but it has. slot 1 in the AMS 2 pro wasn’t feeding. now is. thankyou good sir.

The designer has replied

@hholderness

so glad this was able to help you! I was so frustrated by loading various filament. but like you this just works perfectly. the tension on the spring was too much. you can take it apart and cut off one of the coils. or easier just print this and push it in.

Replying to @hholderness :

I still don’t understand and at this point i won’t investigate. it works on both mine. I did a benchy test that changed colours every layer and not one fail, where prior it was failing every time it loaded slot 1. this needs way more notice and recomendations.

Works great no more issue with the load fault in spool 1 and 3, thank you. Oh I printed both sizes and one is in each AMS 2 Pro

@cpsadowski

This one makes more sense.

This worked great, after installing I don’t get that error message about to much load on spool 1 and 3.

The designer has replied

@hholderness

SUCCESS! Share with your friends I hope we can get more people back to printing instead of waiting on support.

@EspoMan

I’m having this issue with my brand new X2D AMS combo. Going to try this today! And pros/cons between the different versions you have?

The designer has replied

@hholderness

if you have a small fingers, the mini version will work well. I have fat sausage ginger so the bigger one makes it easier install. you do have to push a bit to get it in there and it is secure.

@EspoMan

Replying to @hholderness :

LOL! thanks

Jealous! I have printed tons of stuff in PA6 which has been nice on the X2D. what brand do you use?

@20sBurning

Replying to @hholderness :

I used the polymaker fiberon. it printed super nice. very strong odor during printing process though

@20sBurning

Replying to @hholderness :

oh sorry. didn’t understand the question. I’m running a X2D and a P1S. I printed this on my X2D

I didn’t even know what to search to find this. after getting some filament jammed in my AMS, I did some searching for how to take it apart and solve the problem. Shortly after, the algorithm served this up to me, and I don’t know why it works, but it sure did! I will be boosting this repeatedly. This is incredible.

The designer has replied

@hholderness

Woah thanks so much for the boost! I am so glad this was the quick and easy fix. For a 6 min fix and no-risk of reversing this. I feel this is the best option to resolve our issue with the AMS 2 PRO shipping defect.
