I installed my AMS lite today and opened a package properly labeled as PSA Basic “Bambu Green” that I had ordered.
The AMS identifies it as PLA Wood (Brown).
A second PLA Basic “Bambu Blue” is identified correctly, so it appearts to be a RFID issue on the green.
Changing posts or turning off and on doesnt fix it.
How can I deal with this other than taking the spool apart and removing the RFID?
Refills or with spools?
If refills, you may have accidentally left the previous filaments RFID strip in place.
New spool. Says PLA Basic on the plastic spool, and box is properly labelled as PLA Basic Bambu Green
You can edit and override a particular AMS filament on an X1 screen, I’m assuming you can on a P1 also but have never done it. Don’t know about the A1, but you probably can.
From studio you might just be able to click the edit button on the AMS display and change it to whatever you want.
I cant see anywhere to do it on the A1 screen.
If i select the filament and Edit, the only thing it will let me change is the Dynamic Pressure Control
I can’t get to a live A1 from here to try, but you might be able to edit it from either the handy screen or the studio AMS screen also. Click on what looks like a pencil on the filament.
I have a p1s and do not have this option in studio or handy
On handy, click the blue AMS button. Don’t the filaments have a little pencil on the bottom? Click on that and you’ll get a screen to edit the type and color.
Only non rfid filaments have the pencil, filaments with rfid have an eye instead and cannot be edited
Sorry, there may not be anyway to do it and I don’t have access to any of my printers to run tests. All I can say is I’ve done it from an X1 screen before for the same problem.
If I was in your situation and didn’t have an X1 I’d try microwaving the spool for for 1 second to kill the NFC tags, but I’m pretty reckless and wouldn’t suggest that anyone else try it.
I certainly can’t do it using the Bambu Handy and my P1S printers for Bambu filaments.
Give me a minute, I will plug my AMS lite into my A1 mini (dot ask) and I will double check the screen to see if overrides are possible p.
I don’t doubt your belief, but, two people agreeing is helpful.
Update
I concur, BL filaments can’t be changed from Bambu Handy or the screens of the A series, I assume that is also true of the X series, P series is ignored as the AMS is not controlled using that.
Workarounds
Live with the issue.
Accept what it thinks it is ad when you go to print target the correct one. PLA Wood and PLA Basic are so close, Bambu Studio will happily use one in place of the other.
Remove the RFID Tag.
Not easy and prone to mishaps p, only do this if you feel confident.
A. Wrap tape around the visible portion that will provide strength for the next stage add liberally as the core strength of the structure is important.
I have done this part, not for this reason, but, a cautious approach is required p.
B. Unscrew the spool adapter by turn the two sides in opposite directions, carefully and slowly to not dislodge the tape. Best to do this with one side facing down on a flat surface.
C. Carefully remove the side and do this with the least directional force possible, straight upwards then off.
D. If you have done this correctly you should see one side with an RFID tag flapping freely. Cut it off.
E. Carefully place the side back down touching as little of the filament as possible to not trigger an unfurling.
F. Flip over and repeat.
G. Once complete, carefully remove the tape.
The filament will now act as undetectable filament you can assign as the correct one when you install it.
Return it
Create a ticket and tell them you have an incorrectly detecting spool and you want what you should have received.
Provide a link to this thread to show you have performed all the tests possible and the wisdom of the crowd couldn’t fix the unfixable.
Do not expect that to be quick.
Thanks for the advice.
Im printing “around” it right now, its a pain, but seems to be working. All my other spools identified correctly.
Just wish we could override an RFID if it is in error.
You can try unscrewing the spool and then removing the RFID so it does not try to read it once you add it back on. From there, you should be able to edit it from the app or the software as needed.
Like this step, I detailed above?
You might try slipping a piece of aluminum foil over the RFID tag on ‘Reader’ side of the spool (side between slots 1&2 or slots 3&4). This should shunt the rf reader and render the data blank. I have not tried this, but it seems plausible.
It’s also safer than trying to open the spool and removing the tag.
Copper sheet would be more effective, but harder to acquire.
No harm in trying, but I wouldn’t expect aluminum to do anything. NFC tags like that are H field. Copper might work better since it is so conductive you’ll get some counter eddy currents.
Yeah, don’t do this.
Is there any reason not to change the filament in studio to Basic Green and then when you print it and it does the assignment pick the “wood brown” for the filament to use? Once you do the AMS sync (assuming you are even doing that) the filaments are all still changeable, just don’t sync it again. When you go to print it assign the green to the desired AMS slot.
