Filament type warning

So with the latest version of Bambu Studio 2.1.1.52 I synchronise my printer wiht the studio and I’ve got externally loaded Generic PLA on the printer. I then select that as the filament to use for the object, and hit Slice Plate. Once the plate slices I go to print it and it asks me which filament in the AMS, and I again select the external filament, and it then gives me a warning that this isn’t the filament I’ve sliced for.

Looking at the process: Objects section it shows “Filament 5” which is the external generic PLA filament. And in the Preview mode in the slicing results it says Filament 5.

Why do I get this warning?

On the pad of the printer, have you told the machine that the filament type is PETG/Nylon/etc? Non bambu-RFID filament won’t automatically assign on the machine.

No On the printer it’s Generic PLA, and that’s what it comes in as when I hit the sync button on the Studio software

Strange, I dunno sorry.

Grasping at straws:

  1. On your computer, the Generic PLA filament profile is still of : “Type: PLA” in it’s dropdown?
  2. On the physical pad of your printer, away from your computer, under filament, it shows that ext roll both: exists, and is of type “PLA”? Any fields missing?

I don’t have an X1c but to print from the external spool, dont you need to unload/uncouple the AMS and then load your external spool’s spaghetti into the machine by hand? Have you done that? https://wiki.bambulab.com/en/x1/manual/switch-from-ams-to-spool-holder

No you don’t need to uncouple the AMS, you can just load it, especially if you have a four way adapter ont he back of the printer, the AMS goes in one and you can run external filament into the other, you just can’t use the AMS at all when external filament is loaded.

One clue is when I click on print plate it shows up with “Send my print job” and it’s picked another filament not the one I asked it to use, here’s a snip where you can see everything set correctly yet the warning.
