My 3 week old A1 has been having problems with freezing during a print (in addition to network problems). The screen will become unresponsive and in some cases go blank. Sometimes, the print will resume anywhere from 1-5 minutes after freezing and something it will just remain unresponsive until being powered off.
This seems to be happening more frequently when printing with Overture PETG which I made a few minor settings changes to from the Bambu PETG Basic profile. But this problem still occurs when using PLA (both Bambu and Overture).
So far I have tried turning off the camera, factory reset, new microSD. I’ve had a support ticket open for over a week now with several days between responses so I’m wondering if anyone else has experienced the same issues or has any other suggestions.
Attached the modified settings I am using for Overture PETG.
I’ve been having the same issue. I just received my A1 last Friday. I have been using eSun PLA+, on a slightly modified high quality preset.
The printer will freeze up for minutes at a time, and wil eventually resume the print leaving a nasty layer shift in the model. The nozzle and bed temp will read as 0 degrees on the built-in screen whilst it is frozen.
I experience the same issue. My printer freezes for 5-10 seconds, the temperatures display as zeros, and from what I can tell, it seems to lose connection with the SD card and then reconnects. After bed and nozzle temp was restored on display printing resumes.
This just happened to me too. Froze while printing, nozzle and bed temps shown as 0, filament shown as unknown (?), and while I was trying to figure out what to do, it just resumed and got back to normal. Still, a defect in the print is now noticeable…
What a coincidence: While I was reading this thread, the same thing happened with my printer too. Same symptoms as DManel has described, but it seems there is nothing wrong with the printed object.
I experience the same issue. My printer freezes stop’s moving screen goes black for 2-3 seconds it comes back on then for 5-10 seconds it show there’s no current print, the temperatures display as zeros, and still no movement then after a moment the bed and nozzle temp are restored on the display and then the printing resumes but without the image of the model on the screen just a % with default white objects showing or the background.
I have exactly the same symptoms. The screen turns black at a random moment, the nozzle temperature drops to 0 degrees, then the model loads, the temperatures return to their normal temperature and printing resumes.
Do you think resizing the SD card and restoring the settings will help? maybe it’s a software fault?
Have you already reported the problem to Bambu? The printer is A1 mini.
Hab das selbe Problem, hat heute angefangen in einem 30 Stunden Druck. Temperatur auf 0, keine SD Karte mehr…hab dann einen Werksreset durchgeführt und in diesem Modus hänge ich jetzt, da er immer wieder sich selbständig zurücksetzt. Davor keine Probleme gehabt.
I have seen it happen a few times as well. I am a brand new A1 owner, got it in early June. I watch it a lot because it’s amazing to me how it prints. I notice it freezes sometimes for a few seconds then resumes. I have a screen cover so never noticed the temps going to 0 but if I am watching it and it happens again I will check that. I did notice when I had the light on that the camera light flashed when it started up again like it lost power for a split second.
I’ve also got the same problem. Its like the power shuts of for a very small moment so it kind of resets. I’ve pauzed and resumed the print every time so it continue’s where it was.
I also have this “mid-print-pause” problem. Brand new A1, printing its first model after successfully printing the Benchy on the SD card. At first I thought it might be something to do with the WiFi connection, but the pausing behaviour persists even when WiFi on the machine is turned off. Elsewhere it’s suggested perhaps it’s the SD card itself… a frustrating start! Given there’s no responses to this thread I think I’ll contact Bambu directly.
Strange thing. Since the problem is global and affects various printers, maybe something on the Bambu server side? Because probably all printouts go through their servers. Unless there’s a faulty part of the motherboard? Maybe someone has already reported this to Bambu?
It’s upsetting to see this issue affecting so many new users. After I posted in this thread, I contacted Bambu directly and I’m still waiting for a response that isn’t automated.
At the moment it looks like either an issue with the SD card, the SD card reader, or the Printer’s power delivery. I’m hopeful this is something that can be fixed via firmware, but I’m not holding out much hope.
Has anyone here tried replacing the SD card in their printer in response to the problem?
I’ve tried new SD cards as an attempt to fix the problem. I’ve started to get some more stability after doing a 3rd factory reset and only using PLA. Next step is to try using PETG again and see if the problem recurs.
I had originally thought it was an SD card issue when the first couple people reported it. Now it seems to be many people across two different products lines/firmwares all happening at the same time. This would lead me to believe it’s not hardware related but perhaps something cloud related. It could possibly even be something nefarious from an outside party.
