Error message HMS_WARN_07ff_2000_0002

This is a great tip for finding the messages that are not documented!

Seeing the definition makes even stranger that I see the message after loading the new filament during a switch on my P1P. By then the filament is no longer missing.

So, I do get my same error message when loading filament from the external spool still. I do plan on running PA,PC glass and carbon fiber from my filament dryer to the machine so I do hope to see the bug fixed because I hate to see error messages on anything, if there is one dummy light on in my car it bothers me and I’m a auto tech that knows better that some lights are not as serious as others but still if its there it is annoying.

So glad I found this thread and the consensus is that it is a harmless bug. I get the same HMS_WARN_07ff_2000_0002_0002 error every time I’m loading the filament. It comes and goes like 10 times until the print is started. After that it is gone until I try to load another filament again.

Nothing pops up on the app or in the slicer.

Same happening with my P1P. New machine. Seeing the error when changing filament.

Same here but printing without any issues.

HMS_WARN_07ff_2000_0002_0002

after changing filament and nozzle-cooldown

Just got this error myself, but looking up the earlier mentioned hms_en.json file lists these two errors as follows which make sense to me as they occurred after I unloaded the filament and didn’t immediately put more in.

        {
            "ecode": "07FF200000020002",
            "intro": "External filament is missing; please load a new filament."
        },
        {
            "ecode": "07FF200000020004",
            "intro": "Please pull the external filament from the extruder."
        },

Same problem with my P1P which is 4 days old and the latest firmware that I installed during startup.
HMS_WARN_7ff_2000_XXXX appears during a manual filament change and when the nozzle cools down…
No impact on the impressions but it’s a bit heavy for a new machine.
I will see what Bambu Lab will answer me about this error

I have come to the conclusion it is a firmware bug, I ignore it…as duana777 sated he seen in the json files of bambu studio its for filament runout that I belive it happens when your are between filaments and when you go back to the main screen its a old message…I dont see it at all when using AMS units.

Same error here.
I have it always! while unload / load Filament.
Can print further if I ignore the message.
But by now I tried to print a two-colour-stl. One colour at the bottom, pause and filament change, print the rest with different colour. This failed showing this error again and again. Printer tries loading filament, shows the error and tries reload…
So I have to stop the print, load filament manually and restart it at the already reached high.
That’s not as funny as it sounds…

by the way, no AMS installed…

Same over here, get the same message, Will wait to see what Bambu pushes out to fix this error code.

I get these two every time i print:
HMS_WARN_07ff_2000_0002_0002
HMS_WARN_07ff_2000_0002_0004

No problems when printing though, everything works as expected. The beeping is quite annoying…

Same error here right after clicking ā€œDoneā€ after the filament load, lasts a few seconds and then everything prints just fine. Still disconcerting as a new user.

Another vote for ā€œsee error message, ignore it, goes away and print continuesā€.

Same error messages as well after loading/unloading it seems.

I kind of have the same error message. I got some crappy Eryone filament that got stuck and the priter wasn’t pulling anything. Had to unload the filament, cut a piece of it because it got tied up and now it woun’t load it again.

If I turn off/on the printer the print can resume, but no new filament is coming out, even that I feeded the filament into the AMS.

I have just received this same error message, and I saw the nozzle prior the printing with a piece of filament poop on it. So I guess somehow the printer detected there was something wrong and shown that error message.

Note that the printer was still continuing with the printing process (it was at the beginning, while calibrating the hot bed and so)

hello, i have the same error code. my ams has full spools of filament, and i have the lastest firmware. not sure how to proceed. i am at a standstill…

Thank you, Shawn

I just got like 20hrs ago the P1S with the 4 AMS from Bambu. I have printed like 6 models and the last one required 2 colors, were loaded just fine in the AMS. It prints the first copy of this model just fine, in 2 colors, no issues, no messages. Starting the print for a second copy of the same model, it prints the first color just fine, then comes the change to the second color… the printer halts and spits out this weird error and nothing else works: I finally manage to get to ā€œunloadā€ the second filament but only after I cancel the print job ! I just lost 55 min and some filament and I wonder if this error stops the printer again ? I will contact Bambu and express my frustrations (regarding their machine).

Which error does it show?
