Hello everyone,
I have a P1S that I’ve been using for over one year without any problems. Recently, small printing defects have appeared on only one side of the printed object, as the photo shows.
The print head is new and calibrated, the filament is dry (10% moisture), and I’m using the basic settings for printing (Bambu Studio 0.20mm Standard BBL @X1C ) with PLA (Maroon Red 10205).
I can’t figure out the cause of this problem… Any suggestions are welcome!

Did this start after an update?

No, this is not related to any software update.

I have had my printer for a while, made so many projects and now all the sudden my prints suck. started when the filament got stuck in the extruder, fixed that, and put on a new nozzle. And now my prints are just off, tried adjusting nozzle temp, bed temp i am at a loss. I have so many projects I want to do URG help.

sorry wont let me upload a photo.
