Hey everyone, fairly new to 3D printing here so bear with me. 

I've been pulling my hair out with my P2S for a while now. Every print eventually turns into spaghetti, no matter what I do. The thing is, during my first month I had zero issues — printed over 50 things without a single fail using Jayo PLA with the generic PLA preset in Bambu Studio. Never had a problem. Now it's basically unusable.

The problems seemed to start (or at least got much worse) after I printed PETG for the first time. Since then, even going back to PLA, everything fails. I've cleaned the plate thoroughly and even replaced the nozzle since then, but no luck.

Here's what's going on:
- First layer sticks fine every time, no issues there
- Spaghetti shows up mid-print, sometimes early, sometimes at like 50%
- Happens with ALL geometries - tried a simple ring, a large flat piece with grid infill, small parts... all fail the same way
- Using Jayo PLA, tested with multiple rolls, same thing
- Just installed a brand new nozzle, had the exact same problem with the old one
- Temps are 220°C nozzle / 55°C bed, airflow set to cooling mode
- Printing at standard speed (100%)
- Using the generic PLA profile, haven't touched any advanced settings

What I've already tried:
- Cleaned the plate with dish soap + warm water
- Cleaned the plate with isopropyl alcohol
- Swapped to a different PLA roll
- Replaced the nozzle entirely
- Ran ALL the calibrations in the P2S menu, including the optional ones

Nothing made a difference. I'm honestly lost. It's clearly not an adhesion issue since the first layer is always solid. Something just goes wrong after a while and the print turns to spaghetti.

Has anyone had similar issues with their P2S? Could the PETG have messed something up permanently? At this point I'm wondering if it's a hardware defect. Any ideas before I open a ticket with Bambu? Thanks! 

P2S keeps making spaghetti on every print - running out of ideas
