Bambu Studio Crashes, Slowdowns & Freezes

Bambu Lab Software

Since Bambu Labs “upgraded” Bambu Studio to 2.2.2.56 for macOS the software has become unstable. It stops responding to button clicks so you have to quit and reopen it. Then reopen the model you were working on. Also, adding models to categories takes way too long. You click the collect button, and it takes about 20 seconds or more to open the category selection. I only have 5 categories too. This indicates either a bug or memory handling issues. (My MacBook has 64GB of RAM so it’s not running out of memory, and it only takes about 14% of my M2 Pro CPU) Also, the app will completely freeze up if it’s open too long forcing you to force quit it, If it doesn’t outright crash. This also indicates a memory leak most likely. The previous 2.0.x.x software didn’t have this problem and the performance was snappy.

My question is, can I downgrade the software to a stable version—assuming I can redownload it? I have an X1C with the latest firmware.

Check your Downloads directory or Mac file system for files named similar to Bambu_Studio_mac-v02.02.01.60.dmg . Double click and the replace it with a different version.

Thank you for reminding me the compressed app might be in my Downloads folder. (Which it is!)

Thank you for the link. if downgrading to v2.1.x doesn’t work I have another resource to try.

Im finding wild instability with the current 2.2.2.56. I get one print out of 5 that doesnt crash. Im running Win10 on AMD 12c/24t cpu with 128gb of ram and an Nvidia A6000 with 48gb of vram. Plenty of power to run Bambu Studio, but its so incredibly unstable I cant get anything printing at this point.

I am also having problems with latest version. Crashes when downloading from online models and if it does download I am seeing a lot more printer errors than in the previous version. I will roll back to the prior version or worst case install Orca

Is this topic showing “solved” because folks are recommended downgrading?

I’m also having wild slowness when downloading files, something is wrong with this release…

I wouldn’t say that it is solved, but that there’s a workaround. Temporarily downgrading until the problems are addressed.

Downgrading isn’t a solution, it’s a workaround. It’s also been more than 3 months and several release have been made, and I’m still experiencing this issue today using the latest Bambu Studio (2.4.0.70) on an M4 Macbook Pro running latest MacOS Tahoe.

The issue started for me when the filament grouping popup was added as a hover state to the “Slice plate” button, which was around the time this post was created, and has never improved. I haven’t figured out the exact interaction that causes it to break, but it’s something like if that menu has opened and I click “Slice” after hovering it, my cursor no longer has any effect when I click anything in the UI. This happens at least once every day while using the studio so it shouldn’t be that hard to recreate.

I’ve had some luck using the tab/space/enter keys to navigate whatever is open on the screen, which gets me to the point where I can at least save the file by using the MacOS menus, but I always have to restart Bambu Studio to restore my cursor’s functionality.
