I started printing recently with the Bambu P1S as well, been really fun. I like creating things in cad to print, not an expert by any means, but okayish i guess haha the p1s has been really reliable so far after about 2kgrams printed so far.

What filament have you been using? I'm playing petG
Ive mostly stuck to pla so far. I have used some of bambus translucent petg. I tend to get much more stringing when using it, might have to adjust the settings, or perhaps my nozzle was just dirty. I think humidity can cause the stringing too, but not sure why it would only be when i use petg.
I've got to watch some more videos and maybe adjust the settings as well
I used a sunlu brand pla as well and it wasnt able to retract in the AMS, figured out that the spool just sat in a different groove than the bambu spools did, so always make sure that your spools rotate easily with the AMS. I was worried all day about something being wrong with it haha
