Adding weight to the filament spool is a way to fix the jamming problem while loading or unloading the filament in the Bambulab's AMS.

Now I know how to fix the issue I've been haing AND find a use for the metal slag I've had lying around from old weighted work out gloves. Thank you!

I solved it by placing a 30ml essential oil bottle sideways, filled with steel bearing balls.😊

Good to know. I only had issues with cardboard spools. Must print a bunch of these things. Thanks for sharing

Used the head of an old hammer and some of the packaging material that came with the printer to make the hammer head set inside of the spool center. Resolved my stuck spool printing issue. Will do a more permanent solution like you have.. thanks for the research put into this.

For cardboard spools in an AMS you use large 3/4 drive 1 1/8 to a 1 1/4 impact sockets that rolls inside the cardboard core.

I found BB's work perfect! Nobody has an exact size steel cylinder. Just put some BB's in it and bingo away you go. No fuss no mess.

Actually you need only a cylinder, which goes through all those four filament spools and the weight it has to pick up will be the sum of all the filament spools. This way you won't need any weight actually. And for the cylinder, you can print it yourself 🙂I printed a cylinder of 335 mm length, and 53 mm x 35 mm diameter for the cylinder circle.

I dont mean to be snarky but…. Did you try closing the cover? I don’t need any of this and closing the cover and keeping it closed seems to be… you know, the solution.

Is the file for the center piece yours? Available for share?

Thanks for identifying the issue, but printing a 500g weight seems to be a wast of filament. I have 2 AMSs, I'm sure those who have 4 of them will agree more. I put a generic drug bottle with full of screws in it. We'll see whether it works!

Just make the ptfe hose longer it will fix the Problem too. And its easyier way.

Does it still do that with the lid closed and locked?

They suggest not to use cf filaments in the ams

Keep the AMS closed and twist the two latches 90 defrees to stop it from opening. Then the spool cannot jump out like that as the cover holds it down.
