In the past they did an announcement post asking for additional participants to apply when they needed more.
After update, my printer is now executes âchange filamentâ from AMS slot 2 to AMS slot 2 after each layert, and in most cases compains that the filament cannot be either pulled or pushed. âretryâ always works. I also verified that the filament is not actually stuck.
but in the first place, why does it try to change filament if the next layer is the same filament? and in the model preivew it did not plan for these changesâŚ
anyone having similar issues?

You can open a ticket, and supply the printer log file, and Studio log file, and the Print 3MF file. The last time I heard of this, the file showed a layer filament change from the same filament to the same filament. That doesnât mean that is in your case. In your case how often was it doing that, every layer change, or just once or?

Downloaded the new Fireware but the download didnât completed and stopped at 96%. I turned off and on again. But now the printer only shows me the start screen with the Bambu Lab logo. I hope someone can help me

OK, via Handy I would suggest you roll back the firmware to the previous version. Hopefully that goes fine. (Assuming it shows you on the new version of the firmware. Then you should be prompted to upgrade to the new version again. Hopefully that will work to 100% the 2nd time. Also do you have any AMS or a Hub? If so what firmware versions are they on?

Power cycle the printer. The fan should actually turn off pretty quickly after turning it back on. If it doesnât confirm you are updated to the current firmware. You can open a support ticket and provide printer logs. Once you move the tool head the fan will start up again until it enters power save mode.

I can confirm that my fan do not turn off, and Iâm on the latest FW. May it doesnât work like intended because of the installed Noctua 
and the Noctua is much much quieter than the stock one 
And also the new load/unload routine does not turn off of the nozzle heater after it purged some amount of filament. It stay at 220 for PETG

Yep, it stays hot.
Fan on/off is more random now. I hear it turn off before print start sometimes? And after print finishes it takes some time to turn it off.

Possible, you and I and several hundred other owners voided any hope of rectification from BL for putting in an aftermarket fan if there is a firmware glitch that does not play well with non BL parts.

Seems like auto-filament change with the AMS is broken in some cases. I had two generic PLA black loaded and the failover to the other spool didnât work and I had to do it manually. It is possible that it happened because I sliced the print with the Bambu PLA profile actually, though that shouldnât matter I think.

Nice⌠In a follow up of that⌠Will you also please enable an option to automatically turn off all lights (Enclosure and Extruder)?

So far so good for me. Only small thing I found was, the indicators for the hot end and bed when heating, they donât turn âonâ (orange color), on the touch screen.
@WillItPrint I am having the same issue after the last update, I can print directly through the cloud, however I cannot send to SD cardâŚI have even done a factory reset. On top of all that, the timelapse no longer worksâŚI have reformatted the SD, using same file types as before, same name structureâŚlesson learned about jumping onto Firmware as it is released.
Thank you for saying what I was thinking as wellâŚ
I just had the same problem todayâŚExcept I have not updated my printer since March, or even used my printer for over a month, and I could not get BS or the Handy App to see the printer, which passed all network tests. So it might be a Bambu Handy App issue after update that nobody has noticed that is causing this, and are blaming the printer firmware or BS software.
Here is what I did - Started from scratch on the printer âScan qr code with phone and Handy appâ then ultimately rebind my printer with the app. Then all my issues went away - even BS could not see it until I did that.
I STILL HAVE NOT UPDATED MY PRINTER FIRMWARE OR BAMBU STUDIO!
Hopefully this helps some of you out.

I am also wondering if the last outage crashed a server storage and accounts were corrupted, by lost or jumbled users profiles and data.
In the past week, and since the upgrade, I am having issues where filament will not unload. I tore down the extruder assembly to check, no issues. If I remove the Bowden tube from the top of the extruder while in an error state, there is always about a half-inch of exposed filament. While the tube is removed, I can tell it to retry and 100% of the time it will unload the filament. If I take the tube and push it back into the extruder before retry, it will fail 100% of the time. Today I had the same issue with a print, someone else reported similar issue, where it tried to unload and reload the same filament for an in process print that was at about 10%. Had the same issue where it couldnât unload the filament. Removed the tube from the extruder, told it to retry, unloaded successfully, plugged the tube back in, told it to resume and voila. Have to assume this is firmware because I canât seem to see anything else wrong.
