I recently updated sometime the morning of 5/14/24 and didn’t note the version number. But I’d like to state it completely ruined further prints the moment after updating/upgrading to the beta version on the A1 Mini.
-
Out the box since (5/7/24) not a single issue and printed flawless on the full release 01.02 firmware.
-
Latest (5/14/24) beta ? v 01.03 ? failures across the board from bed leveling, build plate adhesion, mishoming, extruder clog…
I’ll happily advise against the latest public beta A1 Mini firmware update and please use caution, I even did due process and power cycled, calibration, test print which failed upon failure and I then became confident this was the issue due to beta firmware. I’ll update in the morning after running the tests back on previous full release (current) firmware v 01.02 but I’d say it went from ( 0/15 print fails since 5/7/24 ) to ( 8/10 fails 5/14/24 ) immediately following the update.
BEWARE
- I reverted back to previous firmware
Just updated an hour ago, first PETG print worked fine with none of your issues. Beta 01.02.01.32

Wow, well good to know it might be contained. First [Red Flag] was when I first seen the update notification via [Handy App] I chose to update from there as I was away from work.
When I got back it apparently failed which I power cycled and continued to update from the machine directly since it brought up the notification as well which passed that time and I continued with another power cycle - full calibration - test print sequence…
Everything had failed since which is what brought me here and had me revert back firmware. I’ll update later in the morning.
I hadn’t seen any news of the beta so asked upstairs and got an answer back it was ok to run. I’ve seen what happened recently with fw’s in between beta’s on the X1 and how muddled that was so decided to ask for news.
So far it has gone ok, I’m keen to see the adaptive mesh they’re introducing as I used to love the Klipper one. Just running a ludicrous benchy and it actually tested bed around the model, seems good.

Could you please post the specifications on the latest Beta version? I didn’t see anything either since I haven’t updated to the latest studios either
where you find it? I cannot find it bambu wiki.
The FW release note was from Studio, I haven’t seen any other info to date. Was a bit cautious installing it but there is a 50/50 chance it’ll work ok so far 
I reverted back, exited the beta program. Then printed a few test models and seems to be good again. Looks like issue was somehow the head didn’t fully engage when cutting the filament so it went to cut then rapid moved back to purge wiper and AMS started to pull but no worky then alarmed out.
I joined again but it was very suspicious… I bought 1 mini on 5/7/24… now I have 2 more coming tomorrow 5/17/24… lol
Ok I’ve only done single colour today so far, I’ll do a multi later on and check
I just completed my first print with this firmware using a difficult to calibrate translucent pla with a complex part and the results were outstanding using default highquality settings on a .4 nozzle compared to prior firmware and studio. I feel like I am back to set it and forget it status with this printer which is awesome.
This beta has been ok over the last week an a bit, the bed “levelling” seems to be the only thing improved so far in my use. The AMS/filament management is still clunky as ever imho and honestly is far from intuitive. Nothing is worse at least, no dramas.
Getting both models of the [A1 Mini] 1xCombo & 2xStandalone, I’ve more so noticed design changes and differences with the two…
Out the box combo model had [non-logo plate] both standalones had [new logo plates] but with a very very bad PEI coat which makes the labeled filaments and name of plate barely noticeable. Not an issue with usability of course. 1 thing that did become an issue was the 2x standalones had design changes to the purge wiper. Only 1x had mechanism failure by not retracting back after the wipe maneuver. Come to find out the metal frame was oddly bent and extended past the front which would drop down slightly causing the lever to catch and not go back. This mainly happened when filament would purge onto the middle of the wiper weighing it down as it was extended.
Compared it to the combo mini and instantly felt a difference in the movement spring tensioning as it glided back n forth like slow closing drawers compared to a quick typical spring action. The combo’s wiper also doesnt have serated teeth at the exit side, also noticed the wipe lever doesnt extend past the front edge which makes it not able to catch on the frame and get stuck potentially.
Besides the update to beta failing out the box on the combo mini. The 2x standalones were able to update without issue. I think my issues came up when (i knew it was a red flag) the update failed initially and I chose to retry without a power cycle… I use orcaslicer still 90% of time due to quality parameters are still non existent on bambu studios.
I tried using it mainly after initial latest release but quality isn’t there just yet. It’s very frustrating too when I want to use just 1 go to everyday platform yet they take forever to implement features from one another when everything is open source… Now orcaslicer doesn’t have updated features for hygrometer or translucent filaments and custom k-factor setup within those yet.
The bed mesh was already implemented in OS but in a different way unlike BS now using the contour of the sliced model which should be credited to (Mrisoc’s Professional Ender Firmware) he compiled the source code for this baseline method which would use the sliced models outline contour and tailor it to auto bed mesh.
So my ender 3v2 from 2017 only levels 5 points for a standard benchy within a 70mm x 70mm grid which takes like 20 seconds lol. Yet the X1C & P1P lack this implementation.
I will say the A1 series for only running off a MC and not a complete board is pretty amazing (doesnt even use a MC fan) I wish the very least it was vapor cooled but it’s able to pick up the corners and middle and determine if a bed leveling needs to be done or just pick up saved mesh points to start printing again with is very very nice.
The A1 series hopefully is a small glimpse of handy features we’ll see in the next generation plus even further AI and liDaR utilizations.
