AMS 2 Pro Feeding issue

Bambu Lab AMS AMS 2 Pro
1

(FYI MY ISSUE NEVER REACHES EXTRUDER OR HUB / OR FILAMENT BUFFER)
When trying to use my new AMS 2 Pro, any of the filament will load and travel towards HUB, then retracts. It never makes it to the hub. It does this 4-5 times then gives me and error [0701-8006 094811] Unable to feed filament into the extruder…

However it is not even reaching the AMS HUB. Any of the filament does this in either slot. I have even tried loading manually from the X1 screen. Any position spools about 24" ~600mm of filament and retracts.

Any ideas? I have a help ticket in, but not sure when they will get back to me.

I have an original AMS that works fine. Even swapped which one was first, same thing.

Looks a lot like AMS 2 Pro - Issues with loading filament into Extruder

As @Mac3D mentioned we have an active thread for this and I’m hoping if we relate all our tickets together that perhaps support will take notice.

My ticket number is US250408211001 and we also have US250410692001 if you’d like to relate those to your ticket and mention the thread we have open

Thanks guys. I saw this but figured it was different since mine never makes it thru the HUB. I will add yours to my ticket. Here is my ticket number : US250410781001

I am having the same problem.

My first and only other Bambu printer is the A1 Mini w/ AMS Lite. I recently purchased the P1S with AMS 2 Pro and I was severly disappointed. The AMS 2 Pro was problematic from the very start. It would try to load filament super fast and then retract it superfast and I’d get errors when trying to print from it. The AMS Lite worked almost perfectly from the beginning and I can’t believe this AMS 2 Pro was so poorly programed or designed compared to the AMS Lite.

I’m having the same issue. I haven’t gotten the filament to feed all the way to the hub. Sometimes it doesn’t even get out of the AMS before retracting and giving me an error code to trim the end of the filament flush?… haven’t gotten anything through the hub to the nozzle yet.

I’m having the same problem. The AMS 2 Pro doesn’t reach the hub when loading the filament. It tries 4-5 times and then unloads it. I don’t know if cutting the tube could solve the issue. Lost here… very frustrating

So I got mine to work by cutting the PTFE tube from the AMS to the HUB down to about 14 inches. I saw how far it would go outside the AMS and cut to that length since it looked like it could still reach the HUB. No issues with any of the AMS slots or multi-color prints so far!

Hey, I am also having the same issue and I tried to shorten the length of the PTFE tube but that doesn’t seem to help.

Tried. I can feed ASA through easily. When doing multiple colors I have to make sure in close buy or while retracting it won’t actually cause the spool to roll. Just pushes filament everywhere in the AMS. When trying to run PLA or any other. It’s a no go.

PLA won’t make it out of the AMS. Then bites the filament so hard it dents it.

It does all kinds of weird stuff the past few days.

hi would you mind sharing your ticket number? I figure we may share the alike problems

I hope this will help some of you.
AMS 2 pro unable to feed filament to the extruder (error code 0701-8006 025415).
Woke up to a paused printer/unfinished print.
I Disassembled one of my AMS 2 to find broken parts in the 4 in 1 out part.
It broke at the thinnest part.
Seems poorly designed as this part is always under a load…
Support ticket has been opened.

Have been printing for months without issue, now all of a sudden AMS2 wont feed anymore none of the 4 holders. Was amazed to find this long thread. Seems I need to make a ticket.

Exact same problem here, has been working fine since i bought it, hadn’t used if for a month or so, it ran updates and now it does this exactly, all 4 slots feed about 12 inches out and then retract. Took the hub feeder module apart and completely cleaned it, makes no difference. Guessing it must be a change in programming due to the update as nothing else has changed my end at all, same 4 filaments I always have in those slots.

I’ll chime in to mention I’ve got the same issue as well on a brand new unit, just under a month old. US251124897002

Looks like this is a big issue! I received the same message and when I checked the hub, I lost a screw and can’t locate a replacement screw. They even state to save your hub screws when replacing the hub.

Brand new P2S with AMS2 for Christmas here. Same problem. Sounds like we should get Bambu to take the AMS2 back and send us an AMS instead. Clearly the AMS2 has a design flaw that Bambu will not address. Had I known about this issue I would never have ordered the original AMS since I know it works. Very disappointing.

I have experienced the same issue. Ordered a brand new AMS2 Pro and never worked! It’s really frustrating to deal with repairs now. So far I have replaced the internal hub and motor, but filament still won’t reach hub.

I’ve sent multiple pictures explaining visually because I sense a language barrier here, but they now want videos.
