P1S Print successful but missing top 20 layers or so

Been printing the same thing for a while and had countless success with A1, and my first print on my new P1S

Second print with P1S all with same file and settings, told me print successful but failed to print final 20ish layers… everything else looked perfect.

anyone else run into this ?

ive formatted the sd card and that’s it

How many layers do you have in total?
Can you please post an image of the failed print.

Are the last 20 layers printable with your nozzle?
I printed a model a while again with a 0.6er nozzle and didn’t realeased, that the wals are only 0.4mm, therefore these areas were just not printed.

Something like 127ish sorry I can get that info later with a picture. But I had printed the same model previously and it was flawless all I did is go from printing 8 of them to 16, then had the issue. The print was still perfect other than not finishing the top layers.

But also weird it said “ print successful”

had this issue before… as all forums say - do not format your SD card, just replace it to a trusted one

Rollback the firmware to a version earlier than 1.6 via Bambu Handy or replace the SD card.

Hi
My name is Sunil, and I’m new to 3D printing.

My Bambu studio is also showing some missing layers.
I had printed this model earlier, and it had no issues then. But this time I’m getting it.

How you solved it? please help

I just had the same problem with my a1 mini. My slicer shows the top layers but print finish without doing the last few layers.
Already wasted 1kg with this stupid bug.

Any solutions?

downgrade update to the previous version and then check if the problem still exists, then you can rule out whether it is due to the slicer version
