Problem or Use Case

Hi! I use Bambuddy v0.2.4b1 with external Spoolman (0.23.1).

One thing, that annoys me, is the synced tray UUID as "spool tag". I print mostly SUNLU filament.

SUNLU Spool:

Bambu Spool:

Proposed Solution

Only sync supported bambu spool tags, but not tray UUIDs

Alternatives Considered

disabled sync to spoolman.. but this is not a real solution.

Feature Category

Spoolman Integration

Priority

Nice to have

Mockups or Examples

No response

Contribution

I would be willing to help implement this feature

@xeonixo, thank you very much for your report.
I’m not quite sure what your problem is, though. You’re showing a Sunlu spool that apparently has an RFID tag attached to it, which is saved as a tag in Spoolman. That’s exactly how it’s supposed to work. I’m not sure where the problem lies. Maybe you could describe it in more detail.

Best regards,
Sn0rri

@netscout2001 thanks for the fast reply!

Unfortunately, that’s not the case. This tag is also written in Spoolman for other spools in that tray. That's why I am assuming, that it is the tray UUID.

As far as I know, SUNLU spools don’t have a tag; at least, I haven’t found one yet.

Furthermore, I’m quite certain that Bambulab doesn’t read third-party tags, since they aren’t signed correctly.

Oh, thanks. That makes it clearer now. So you have this tag UUID in multiple coils. That shouldn't be the case, of course.
Thanks for the information.

I found those tags on multiple spools from different brands:

6319B70A00FF0000 (GEEETECH TPU black, used on external spool left head)

6319B70A00000000 (SUNLU ABS gray)

6319B70A00000001 (SUNLU PLA+2.0 black)

0F08D7BF00000000 (SUNLU PETG pink)

6319B70A00000002 (SUNLU PETG gray)

Based on this, it's probably based on "generic", "material", "color" and "tray number". But it's not unique.

(AMS 2 Pro, X2D)

Edit: SUNLU PETG Pink was last used on my P1S with AMS Gen1. My fault.

Edit 2: it's probably just the UUID Printer + AMS Tray number

The question is: where are the tags coming from? Bambuddy doesn't write any non BL tags to the inventory.

After thinking about it I'm going to leave this as-is for now. The tag_uid fallback has been in place since an upstream
fix for a firmware/reader combo where tray_uuid isn't reliably published, and the AMS sync path as a whole is at a level of stability I don't want to disturb for a cosmetic Spoolman pollution issue. If a synthetic tag ends up in Spoolman, it can be deleted manually once, or automatically via script; the printer won't keep re-creating it as long as the entry exists and matches by location.
