It seems I have the same issue that others have reported with the AMS 1 — the Bambu spool is not being detected. When I try to get it to read the spool, I get the following message:
Cannot read filament info: the filament is loaded to the toolhead. Please unload the filament and try again.
Funny thing is, when I unload it, the filament slot on the screen appears empty, so I can’t trigger another read. And when I load it back in, it spins a bit, then stops — and still no read.
What I don’t understand is that when I first loaded all four filaments before i took them out of the toolhead to turn on the dry function, the AMS spun them and successfully read the info. So why won’t it do it now when I ask? Any input from Bambu staff?
I read in another post about the AMS 1 that turning off the printer and trying again might help, but I was hoping this issue would’ve been fixed by now.
Mine had problems reading RFID on slots 3 and 4 so I wrote to BBL Support and they sent me a new main frame to install. Haven’t received the frame yet but it’s on the way.
i was able to “fix” it, by taking out all of the spool completely then i placed them on other spot, and each one of them got a read.
but it is still an issue that you can’t force a read if its loaded, and that taking it out just show it empty, but when you place a spool it get feeded then you get a read, so somewhere someone mess up this function and it need a fix.
Hi everyone from Italy. Me too i have a RFID reading problem on AMS 2 Pro connected to P2S. But it seems more a limitation, not a general issue. Some spools are read, others not, whatever slot i insert them in. And ALWAYS the same spools. Same spools which are not RFID read in AMS 2 PRO, if inserted in other AMS HT, theyt are correctly recognized. It seems to be a limited reading capability. I opened a ticket, i hope this helps. I will let you know
does the problem follow the slot or the roll?
I assume you have other rolls to test. Am thinking the tag might be bad, or weak. As a test make sure you test different color and or filament. Maybe it is not the roll but the batch. Not seen this but, it would be a simple test.
Does it test one roll at a time?
The problem is specific to the spool (you name it roll). Example. I have a spool PLA Matte colore white. Whatever slot of AMS i insert it, it is not recognized, alone or with other spools in other slots. BUT if i put the same non recognized roll in my AMS HT on other printer, it is perfectly recognized. On the contrary, other spools (different colors, to understand) are recognized everywhere. What i suppose is that it is a problem cross-generated by 2 factors: weak RFID tag on the spool and/or weak sensibility of tag reader on AMS. Otherwise, i cannot explain why on AMS HT everything works and with other spools everything works everywhere
