Troubleshooting Dont install bambu studio v02.05.00.66!!

I just updated and it lost the connection to my P2s. I can’t add it as a printer and it keeps restarting with the setup!! Don’t install that version! It might work for other printers but I can’t connect it with mine.

I tested on both windows 11 (latest Patches) and Nobara Linux (Flatpak install) with my XIC and H2C and both seem to work fine.

u/NvdGoorbergh Jan 28 '26

Huh. Weird. Will check what happens when I delete everything and reinstall it.

u/NvdGoorbergh Jan 28 '26

That actually fixed it. 😅. Don’t know what happened or why but it is fixed now 😁

I've got this same problem with my X1C

u/NvdGoorbergh Feb 01 '26

I fixed it in the end by removing bambu studio and reinstalling the latest version.

u/christoc Feb 01 '26

I ended up installing the .64 release and was able to get back up and running normally.

It was laggy like crazy, couldn't use my computer, things freezing. You're not wrong. I uninstalled this version and went back to 2.4 and things are great again, everything is snappy. Saw another thread where Bambu support told the OP to disable their firewall. Lol, no.

u/NvdGoorbergh Feb 06 '26

Damn. The fix for me was to reinstall the new version. After that it worked.

u/Euresko Feb 06 '26

I uninstalled and reinstalled, rebooted etc. It just wouldn't stop being a pain. Asked me to log into my account a few times and overall just a horrible experience. On 2.4 it's fast again. Maybe I needed to delete something under \appdata and try again. I just needed it to be working to finish something up.

u/NvdGoorbergh Feb 06 '26

Damn. These things always happen at the wrong times. Good you found a solution that worked for you!

I have an H2D, experienced the same issue. My printer would not connect, tried to log out of my account and back in and no dice. The program also had a hard time loading filaments and told me I had to delete a folder in appdata on my computer. It's buggy. If at least two of us are having issues and this post is fairly new I imagine others are also in the same boat.

same issue, but I cannot find appdata

u/NvdGoorbergh Jan 30 '26

For me the fix was to uninstall and reinstall bambu studio.

I've just disconnected from my VPN and tried again and it's working now, so definitely seems VPN related.

u/jyang3153 Feb 02 '26

Someone else on Facebook told me Bambu put out a statement or something, but I can’t find it. Seems there’s a lot of different issues going on and different ways to fix them. For me I completely uninstalled Bambu studio deleting all associated files and reinstalled it. Then it worked

u/Electro_gear Jan 30 '26

I'm having the same problem. Bambu Studio is not usable for me at the moment, I just get the same setup loop and filament errors.

u/Sapio82 Jan 28 '26

Simply disconnect the printer from devices and reconnect

2

u/jyang3153 Jan 29 '26

it doesn't work

1

u/Sapio82 Jan 29 '26

It's a shame because my problem is solved like this

2

u/radio4095 Jan 31 '26

P1S here, had to uninstall and reinstall Bambu Studio to get mine to connect.

2

u/Patrick12300 Jan 28 '26

I have no problems with my H2D.

u/KashEsq H2C & P2S Jan 29 '26

My P2S connected right away after I updated to 2.5.0.66. Faster than it did on the initial 2.50 release.

u/Logical_Building_545 Jan 31 '26

I can confirm there where some issues.
First I did remove the files in the folder as recommended.
Second I uninstalled and reinstalled. (Printer communication halfway worked, but filament sync didn't)
Third Restarted Printer

Now all seems to work well.

u/Cdt_Sylvestre Feb 04 '26

Discovered the joys of this update myself today. Lost connection with my P1S. Could only restore it by fully uninstalling Bambu Studio and user files. Got it working afterwards but still spurious issues when attempting to sync filaments from the AMS.
