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.
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.
