The “round thingy” is a capacitor. Depending on its function in the circuit running without it could cause other electronics to fail.
hahahaha thank you. Yes - im not using the printer anymore. totally agree.
I received an answer from BambuLab support:
This prompt means the filament at the spool holder is empty. Please confirm whether it is a machine error or there is really no filament.
In my case, filament is loaded and even the printer is working. So maybe a defective filament run-out sensor?

Definitely something with the latest firmware.
I’ve seen that “error” a couple times (since update) when cancelling a print. I’ve just ignored it since it seemed inconsequential.
I’m not normally near the printer when sending prints, but i’m going to try and keep a closer look if this pops up at any other times.

I’m getting a HMS_WARN_07ff_2000_0002_0002 while I’m loading and unloading filaments, and when I start a print after loading. I noticed it after the latest update. I look in machine assistant on Bambu Handy app and there is no messages. I have done 1 9 hour print and a couple of prints ranging from 4-6 hours each since I noticed it with no issues. It’s been business as usual for my P1P, I’m guessing it’s a bug.
Yep, it’s AMS_07ff_0200_or something, reffers to AMS that i don’t have ;), i’m glad i’m not the only one having this, the good thing is that this error pops and it’s gone like in 10 seconds, it happens while switching filaments manually.

Looks like it is a firmware error, and it happens while loading and unloading filament manually thru printers lcd screen.
Yeah that is a capacitor. you can solder it back on. the black line on the top indicates negative. That side goes on the bottom pad.
oh… i see you broke a terminal off the capacitor. But another and solder it on. Use the numbers on top of the capacitor when looking for a replacement.

I just got a new P1P and I get this error occasionally as well. It seems to work fine but is rather concerning since my device is new.
I have the same problem… I have a new printer and I get this error message even during printing, but it disappears immediately… I haven’t noticed any problem yet. I don’t have AMS.

This has something to do with the newest update for sure, I’m not worried about it. If it was a serious/real HMS code it would pop up in the Bambu Handy app under Machine Assistant. Now that I have remote viewing off my LAN I’m not down grading the firmware, I will put up with it.
Same here. HMS_WARN_07ff_2000_0002_0002
This error is not listed. Also, since the update, I have terrible bed adhesion. Was printing yesterday, everything was fine. Updated today, now I get holes and everything. Terrible. K Value is still at 0.020, so that’s not it…
As far as I can tell the warning is shown after filament is loaded using the load command on the printer.
It does not cause any printing issues.
After any update I do the machine calibration, I don’t know if this is needed but did you try that? If so and still have a problem I would try down grading back to you’re previous firmware version and seeing if the issue is gone. Also make sure there is no pieces of filament or debris on the z rod screws and rails, I believe this was the cause of a bed leveling issue leading to bed adhesion I had one time, or I could have been a fluke, but worth checking…only takes a moment, I had a piece of filament right at the very top of the front left lead screw that after removed it was fine. But like I said it could have been a coincidence.
Just figured I’d chime in with a +1. Also getting same error, unmodified machine with latest firmware. Error upon unloading/loading filament. Working fine otherwise.
This is crazy. There are so many error codes that are not documented. Even the ones that are are not always discoverable on the wiki. I have had to resort to google many times to find a code not in the wiki list, but buried on some other page.

If you look in:-
C:\User\USERNAME\AppData\Roaming\BambuStudio\hms
There’s a file “hms_en.json”, in there are the fault codes and descriptions
ie.
{
-
"ecode": "07FF200000020001",* -
"intro": "External filament has run out; please load a new filament."* -
},* -
{* -
"ecode": "07FF200000020002",* -
"intro": "External filament is missing; please load a new filament."* -
},* -
{* -
"ecode": "07FF200000020004",* -
"intro": "Please pull the external filament from the extruder."* -
},*
These are some I saw higher up in the thread.

I connected my AMS today and it has done about 270 filament changes thus far. I have been looking for the warning message that I have been receiving every time I have been changing the filament on the Ex holder but no error using the AMS, my guess is it’s only when using the external spool, I will try to replicate with the external spool tomorrow. I will only be using the external holder for TPU witch is very rare at this point, I use my Ender 5 s1 for TPU so its safe to say I will not have to look at that error message for while. The message does not effect anything other then my head. Side note After playing around with the AMS I learned I need to buy 3 more…
The capacitance (uF) and voltage (V) both matter. And keep track of which side the + and - were on – hooking it up backwards will fry it (and maybe something else).
You want:
- electrolytic capacitor, a good brand (Panasonic, Murata, lots of others)
- around the same or a bit higher capacitance.
- at least the same voltage rating.
- check the size against the available volume; needs to fit.
Seeing it too.
My guess is that the driver for the AMS is complaining that the AMS isn’t responding. Because you and I don’t currently have an AMS.
The only significance (for a no-AMS printer) is that they ought to fix the software to only complain when there IS an AMS and it’s not reaponding.
