My P1S got bricked while printing and I don’t understand how. Please advise me on how to get it responsive again.
I was ~11 hours into printing this model and 93% done: Connect 4-Tex (Vortex/Passthrough Connect 4 game) by evets17 - MakerWorld
It had some major layer line issues at a few points but the print should’ve been okay at the end. I got home when the print should’ve been complete, but instead its just sitting there unresponsive. I didn’t get any notifications or errors, and the Bambu Studio app says the device is running fine even though the printer isn’t moving at all and the print time is unchanged. Its just frozen.
The print head was docked in the front left corner of the machine even tho theres still 7% of the print left to do. And the print head was slowly moving to the front right of the machine, I don’t know the pace but after over 10 minutes it was almost half way there.
I see a string at the top layer where it gave up at. And you can clearly see 2 failed layers on the print so far. At this point the printer is still frozen.
In the mobile app and desktop app and on the printer itself I tried pausing and unpausing the machine and it didn’t do anything.
Eventually I tried power cycling it. The first 4 attempts the machine turned on completely unresponsive with a blank display. On the 5th attempt it finally had a display and auto-resumed but it was complete trash at that point.
Heres another view after it finally started printing again but I had to stop it because the layer wasnt adhering.
does anyone know what couldve caused this? Why did the print just suddenly stop and why did the machine become unresponsive?
And why did it take over 5 power cycles for it to be responsive again?
I’m worried about the longevity of this printer if it runs the risk of just getting bricked again during any print.
What about it seem wrong? I’ve had a few other large print also fail but not like they, Usually my 10+ hour prints fail by severely under extruding a few layers then continuing fine. But I haven’t had a print put a full stop and become unresponsive for multiple power cycles.
Heres my other problem I’m still working on: P1s severely under-extrudes on random middle layers
I’m using the microSD that came with the printer. And all small prints have been a success so far.
That’s a problem.
Cards that are included with printers are notorious for going bad. Usually not the best quality. From any printer, one of the first things to do is replace the card.
Given that my printer only fails on large prints that take 10+ hours, but works perfectly on everything else, this makes sense. Maybe the microsd card is failing, maybe the read/write speed or cache isnt enough to support large prints consistently. Idk what it is but I just ordered a 256gb sandisk card with faster read/write. I’ll report back after reprinting this file on the new card.
a 32 would have been fine. Just be sure to format in FAT32. There’s a few threads on how to do it in Windows. Win doesn’t like to format in FAT above 32. It’s possible though.
A newer build of windows in the beta channel finally adds that feature back.
The timing of this is incredible. I just went to print another small thing and Bambu gave me a read/write exception on the microSD that came with the printer. I tried tinkering with it a bit and it looked like the card is dead… lmao
So I can say with 99% certainty all of my problem are from the card. Thank you for helping me track that down!
