I have 1340+ hours on my P1P and I have not had this issue since replacing my SD card in February 2023. I bought my P1P in January of 2023.
Unfortunately I had my P1P cook that card in April 2024:
I replaced the cooked card with one of these cards:
I bought 2 so I have a spare in case it cooks another one again.
But I have not had any random print failures like the ones described above since the initial card replacement.
That being said, I have never upgraded to the 1.7 firmware. I have kept it at 1.6 since this thread was started.
I do not use Bambu Studio though, I only use Orca Slicer.
I turn off the time lapse capture and only use it when I specifically want to capture a print since I know that it will degrade my SD card faster.
I also check my prints regularly with Bambu Handy, so I don’t think that is an issue here, at least with 1.6 FW.
First step in fixing this issue (if you have not done so already):
Replace the stock SD card. There have been known issues with them for years.
Second step:
Revert to FW 1.6.
Also take a look at the card usage on the printer:
On the P1x panel > Settings > SD Card: (mine says 10.2/57.9 GB)
If the card is approaching being full, it might be time to replace/reformat the card. I don’t know what kind of affect an (almost or) full card would have since I have never had a card survive that long, but it’s worth a consideration.
I just ran a 4 hour long print yesterday with no issue.
