AMS Lite design failure and fix

So a major failure I’ve seen on the AMS lite is a problem that causes

In my experience a simple fix for this is by swapping the spool location. For example, by swapping the top and bottom. So for example with the following picture. If say the problem child is on 4. Without taking the filament out of the AMS. Just swap the spool to the 3 slot while it goes into 4. This gives enough room for it to work.

Basically as the spool runs out of filament the filament has to make a sharp turn. And this change allows it to get around that. Same problem shows up if the filament is to tight. This tends to fix it.

So to BL if you read this. All you have to do is swap the numbers around from 3 to 4, and 1 to 2. And in the software have it swap that around for the NFC thing. And then maybe make something people can print as a cover like this

And this lets the user slap the new cover on, update the thing, and run with it. Simple as that.

But if there was a major change made. Stronger motors or maybe it actually putting a bit more push wouldn’t hurt. Like this isn’t a perfect fix, but it at least makes it useable 90% of the time where otherwise you would manually had to push/pull the filament to get it started or switched.

NOTE/Update: I don’t have my A1 anymore due to the recall. So I can’t test this anymore. However, I might get it again sometime in the future.

我也同样被这个事情烦恼,官方没有帮助我解决问题,给我寄了新的AMS组件,现在还没到,但耗材上的NFC功能确实白费了,谢谢你
The official did not help me solve the problem. They sent me a new AMS component, which has not arrived yet, but the NFC function on the consumables is really wasted, thank you

valid point im surprised they didnt align the spools beeter before production

Wow! Glad you posted this! I’ve been running into this a lot lately on both my A1 and A1 Mini - and kept blaming the filament for it.

(Someone told me this would happen if the filament wasn’t consistently the correct 1.75mm diameter, which makes sense — but hard to believe every spool of my red and white filaments have this issue right now!)

I’m going to try swapping the spools around and see if it works!
