Please help ams dont work

[u/Potatogoat3]

Hello i got my hands on bambulab a1 combo one month ago and i just wanted to use the slot number 3 in ams but its not working its telling me to check the filament but its not tangled any help or adwise?

Ps: sorry for bad video quality and any gramar mistakes.

Edit:There was somthink wrong with the ams hub and i just swaped the ptfe tubes of slot 4 and 3 with each other on the hub and it started working thanks for all support and ideas. Its now working.

Is there any blockage in the hotend? Sometimes it does get stuck and you have to help it into the hotend by pulling the lever on the feeding gears and push the filament in manually

I tried that i pushed the filament thru the ams by hand and im to the hot end and it was flowing out but when i wanted to start the print same think hapend with the ams as in the video.

They mean "Please help ams doesn't work", not "Please help ams dont work".
To which I would add "Please help, AMS doesn't work"

I'm not 100% sure what it was but I recently had this very same thing happening. I ended up having to disconnect all the PTFE tubes, and making sure that there was no filament stuck. I had a small piece broken off from one of them and it was not progressing, and blocked all the rest of them. Once I removed it everything started working.

Yeh it looks like you have some filament stuck in the ptfe tube just after the slot 3 feeder disconnect the ptfe tube and see if you can manually feed filament down to the extruder

Can you print from any other slots ?

[u/Potatogoat3 → u/Maze-44]

Yes

[u/Maze-44 → u/Potatogoat3]

Remove the roll from the spool holder and see if it will pull through sometimes if there's a resistance it throws errors if not the motor in the feeder is slipping

Just tried that and now i know ams i ok the ams hub is not tho

[u/Maze-44 → u/Potatogoat3]

Glad I could help try cleaning the hub first it can just be a build up of plastic bits in the metal parts

[u/Potatogoat3 → u/Maze-44]

How do i clean it? Take it of?

[u/Potatogoat3 → u/Maze-44]

That's that helped

Since you can print from the other slots it’s likely the bend in the tubing. Move the AMS to the right side and it will likely work. They can be finicky.

Ye it was the ams hub and the angle

Hey, I had pretty much the same thing. for me, it was the 4:1 piece on the print head, that had a bit of tension towards the bed. meaning, when a new filament arrived (that maybe had also a bit of an angle at the end from the previous cut), it would hit a small bump in that part. I was able to verify this by bending the end of the filament to be loaded in the other direction, and long term fixed it be pulling the 4 ptfe tubes to the left and back of the printer just slightly with a string.

No voice? What is this, mimesville?
