thank you for posting this. I am new to this and thought I was not setting something correctly.
A1 mini â false âconfirm extrusionâ prompt at every print start cost me money in unnecessary parts. Firmware regression.
Firmware: [version]
Setup: A1 mini, external spool, no AMS Lite, single color.
Since a recent firmware update, every print pauses at the start asking me to confirm whether filament was extruded (âFilament extruded, continueâ / âNot extruded, retryâ), as if filament had just been loaded â even though it is already loaded and printing fine. The prompt reliably comes back after the printer has been powered off for a few hours.
Here is the part that needs to be heard: this misleading prompt presents as an extrusion fault, so I treated it as one. Over several weeks I bought and replaced the nozzle, a complete hotend, and the heating block trying to make it stop â real money spent on hardware that was never the problem. The prompt persisted through every single part, including fully OEM components. It is firmware.
A prompt that mimics a hardware failure, with no way to disable it without also losing pre-print checks I paid for, is actively pushing users to buy replacement parts they do not need. That is not acceptable for a regression introduced by an update.
Please confirm this and fix the filament-state tracking across power cycles in an upcoming release. I can provide logs or video.
Where do you go to roll back the firmware? I was looking, but did not see it in the settings. Is this through the printer display itself or from Bambu Studio?
If you have Bambu Handy then you go to Devices â> [the printer you wish to downgrade] â> Firmware â> I want to update to a previous version â> [choose version you want, I did 1.08.00 and then went back to 1.08.01]
If you donât have Bambu Handy then you can go to Bambuâs wiki and find your printer, then find the firmware files, put them on SD card, then plug that SD card into your printer.
(I donât know how the SD card method works really, because I never used it)

Total BS indeed, we donât need to check correct extrusion as it was working yesterday 
I guess Iâll have to write and complain so they can feel some heat. Everyone here should complain or weâll be stuck with this..

Hello. This can be done through the Bambu Studio desktop application for PC or through the Bambu Handy mobile application!

Bambulab did this for better print quality, but I agree it is annoying when send a 24 hr print and think it will do all the stuff by itself but it waits for you, but if you wait long enough it will do it by itself
I donât see any relation what so ever between print quality and have you click next to confirm filament is extruding. In over 10 years of 3D printing I have never had a machine jam itself randomly over night. And if it did (which it doesnât), it wonât affect print quality, but the ability to print at all. Which the extruder should sense.
On A1 (not mini) I tried downgrading and updating again, but the issue persists; will downgrade and keep that way until a fix comes out, hoping that solves the issue.

Downgrading the firmware it does stops treating each cold print as having new filament (purging âoldâ filament each time); hope they will fix it in a later update.
Same symptom here on my A1 mini after updating to firmware 01.08.00.00. Every time I start a print, it now runs a filament load and asks me to confirm the filament is extruding before it will begin. Hoping this gets fixed in a future firmware update.

My A1 also is having the same issue. It is quite annoyingâŚI hope the will see it and find a solution asap.

Same problem for me. each new print, the printer ask if the filament is well extruded.

I have same problem on my A1. When Đ start printing, the printer asks to load the filament. This is a real hassle if Ń need to start the printer remotely. Fix it pls.
