Filament unknown!?

Bambu Lab H2 Series
1

I am getting extremely fed up with the constant issues of using custom filament with my bambu h2d.

last time i finally managed to get the polymaker pps-cf into the system in a good and correct way. but now when i am going to use it again it is not there and working as expected.

for instance. look at this. it is clearly loaded in the left nozzle, it says pps-cf there, yet below it says the filamen in the left nozzle is unknown and may soften! Why does it say that and how to fix it?

Thanks!

Can you just ignore it and hit send? This shouldn’t force the printer to halt.

so, my question is - Why does it say that and how to fix it?

The things to “ignore” with bambulabs ecosystem is becoming really long. Shouldn’t be that way.

So - WHY does it say that, and how to fix it so it doesn’t think it’s unknown even though it isn’t? Or is this another bug?

Did you set the filament on the machine itself?

This isn’t going to answer the question, but looking at the Studio code, there’s only one situation where that particular warning gets shown – when Studio can’t find a local profile for the filament it thinks is selected in the AMS.

[It then assumes the unknown filament has a temperature_vitrification setting of 43°C, compares that with the set chamber temperature and issues the warning if the difference is <= 5°.]

Somewhere along the line it must be getting confused and not able to correlate the selected filament with any local profile, just for this particular warning check. But why exactly, in this case, I don’t know.

FWIW, the filaments are indexed by an internal unique ID (filament_id property in the profiles). But for whatever reason in this case the ID the printer is using for that filament isn’t matching the ID from the local profile.

This is suspiciously similar to "Select the material type and color first" Error adding custom filament . Perhaps also due to sunspots. Or more likely some cloud sync issue.

I’m not really sure how to force a sync (I personally don’t use any cloud features). Perhaps editing the filament profile. Might be worth a try.

Taking a look at your custom profile may yield some clues, though I’m guessing it’s going to look OK. (You have to rename it with a .3mf extension to post it here.)

yes, when installing/loading it. already had it in the list of filaments as I have used it before.

sounds like a bug, then :wink:
