Filament getting stuck after feeder tube

Bambu Lab AMS Troubleshooting

I have 2 ams’s and both have issues in the 3rd slot with the filament getting stuck after the feeder tube and i have to push the filament through when trying to put a new spool in it for the system to read the tag. Anyone know what is causing the filament to get stuck after the feeder tube? I have taken both apart and replaced the feeder tube assembly and still having the issue.

Same with my a1, when the filament goes to poop, the ams tries to push the filament into the spring thingy, and it just ends up retracting a little. Every time it does this, i just take out the ptfe and then push the filament out, and then stick the filament into the ams slot while pushing the lever on the left of the head. Any idea how to fix, im getting pissed that i have to do it every 5 mins.

Welcome to my world.

I have been through that poorly thought out junction more than once. I have torn it down, designed new feed units you name it. I have tried it finally it occurred to me i hace 2 a series printers. Moved to the second unit, prints perfectly. I am still stunned by the round connector going ro the square channel, lil filing action smoothed that out. But nope. Not a grand design.

I have chatted with a few ppl that had their version of rhe issue. Currently i am waiting on an entire print head to be shipped it won’t do anything i think, but I will have a 2nd spare

So far support has been very nuce, but have absolutely no idea how to fix it

Still don’t regret thw purchase

Do not pull the PTFE tube from the FEEDER slot!! Learn from my mistake.

I just got my AMS and I was trying to clear a filament issue. I pulled on the filament/tube and completely yanked the PTFE tube right out of the gray feeder assembly. Why are these parts the same color as the removable parts? They should be bright red for bulldozers like me!

Since I can’t post a picture, here is a diagram of what happened:

======= FRONT DRIVE ASSEMBLY =======

The tube is still connected to the rear internal hub, but it is completely disconnected from the actual gray feeder unit.

Has anyone else done this? Do I need to completely take the feeder module apart to re-seat the tube, or can it just be pushed back in until it clicks?

I had to take it completly apart and reassemble it T_T

The horror presisted, I printed one plate and changed color and bam my AMS 2 Pro is stuck AGAIN but now its due to the internal Rear Hub where the motor is, Oh lord Satan i’m honostly thinking to REMOVE my AMS 2 Pro entirely because it has worked less than it has been jammed, i’m starting to lose my cool.

It can not be default that one color change results again and again into having to dissable everything and assemble it again then i was better off withouth it :clown_face:
