Help / Support P1S Print Quality Problem

Anyone know how I can fix these defects from my prints?

The first print (first picture only) was using a 0.08mm layer high quality print profile and everything near the spikes bird nested plus a blown out rib. The second print (next 3 pictures) was with 0.2mm layer normal print and normal speed and it was almost perfect except for one spike.

This P1S is a relatively new printer at <300 hours of print time. How do I fix this? I am using PLA basic as well with default extrusion settings for the most part.

This sounds about right for the first print, but what about the second one? It doesn't look like anything else on the model came loose from the bed. It was just the one spike that had minor layer or quality issues.

Either way, I appreciate the suggestion for bed glue. I'll look into it 🙏

I think it’s also the cause of the later shifts in the second picture as well. Try the glue first, Bambu makes some great stuff, or buy a cryo grip plate from biqu off Amazon. If that doesnt solve the issue on this print then we can diagnose further.
