Help - invalid values found in 3mf

After bringing my STEP model in (just a round coaster with heart), I colored the file (2 colors). When I saved the project and later brought it back in, it gave me the above error with:
"filament_flush_temp: nil,0,0,0,0,0,0,0,0 not in range [0, 1500]
Please correct them in param tabs.

Any reason for this, and how do I fix?

No idea what the fix is. But I’ve also had this problem for the last few days

Some additional investigation info: While I am not using it on this print, I have SUNLU PLA High Spped filament and TECBEARS PLA Basic loaded. If I look at their parameters on ‘Multi Filament’ tab, it shows ‘Flush temperature 1500 C’ for both. All my Bambu filamnet has a value of 0 here.
I have not found the ‘nil’ value that shows up in my error message.

I am experiencing this also. I change the ‘flush temp’ to 0 and it goes away. It is very annoying. Hopefully, there will be a bug fix soon.

I am wondering how the non-Bambu filament got set at 1500

This seems to have happened after i did the update to studio. Setting the value back to 0 does seem to fix it, but it’s still annoying

For me, ‘flush temp’ is already set to 0 in Filament settings > Multi Filament

I’ve tried setting it to other random values and back to 0 again multiple times but the error persists.

I’m wondering if it has anything to do with the filament preset being created in Orca Slicer (which doesn’t seem to have a flush temperature setting anyway)?

The only change I made in Orca was the nozzle temp for Generic PETG, and then saved it as SUNLU PETG Rapid.

Just started having the same issue this morning … H2D printer, Invalid values found in 3mf

Same here, and my filament that I set up 2 years ago all in Bambu Studio now has that value too, this is a genuine bug in Bambu Studio it seems @BambuLab


I’m also experiencing the most confusing flushing issues that’s causing prints to fail as well: Unexplainable bug in latest firmware ruining dozens of prints

This thread is also discussing the same problem → Flushing Temp Error in Bambu Studio - #6 by EFriseer

In this thread there was a suggestion from
GraySky

Here is the post and below is the text

Setting the Flush temperature (under Multi Filament tab) to 0 seems to fix the error. I checked all of the Bambu filament presets and they are all 0.

I also had the problem and setting the multi filamant options to 0 it went away. But now with the new BambuStudio 2.1.1.52 the error message is back but now you can’t change anything in the Multi Filament tab.

Mine is even totally empty! I have no AMS, is that the cause?


(“Advanced” is greyed-out because I have Develop mode enabled)

However I saved the project, quit BS and relaunched it, and now the error has gone and I can print again.

I just updated Bambu Studio and am seeing this error but the option to change it is no longer in the Multi-Filament tab. What is the solution?

Same Problem here.

Can you just ignore the error message and print?

Well yea - but then you’re printing with settings that produce bad results…

What I would do is downgrade to the previous Bambu Studio version, go through each and every one of your custom filament presets, and change the flush temp to 0 (and one right below it, I forgot the name). After you have done all of that, upgrade BS to the latest version 2.1.1.52 and there will be no errors. That’s what I did.
