I finally joined the Cult... a few Days Ago!

Here is all the Stuff I printed with my new P1S thus far!

Since im here, I'll need a bit of advice/guidance tho... For one, sometimes the nozzle doesn't clean itself properly and flings its poop on the bed. From what I read I can put an A1 Nozzle Wiper somewhere to insure it cleans better?

And for the bigger, what I asume to be Issue, even when it wipes itself successfully, there always comes out a large string of Filament afterwards, which the P1S does not try to clean. Then going on to print away with this string still on. It seems very unintentional.

While this is manageable in single colour prints, it makes using the AMS basically impossible, as this happens after every Colour change. This is what the bed looked like after my only proper Multicolour Print...

Anyone faced the same issue who could maybe help me?

Really getting tired of the Bambu Lab fan boys, there are already too many of us!
- Hey there are other great printers but also it's fine to recognize a great printer.
  The rest of the industry is quickly playing catch up because the quality and the absolute bar lowering the printers from Bambu labs have done.
  QIDI and the new Creality printers are already way better for it and we will hopefully and likely see more innovation from trying to dethrone them.
  All to say I think the cheers are justified and worth it. And as soon as they are worth it I think people will stop.

Welcome!
To answer your question, what's happening is that filament in the meltzone of the nozzle is melting and oozing out after the nozzle reaches temp. It will stop oozing once the tiny bit of filament in the meltzone melts and subsequently oozes out.
I am not a Bambu user, but if you can preheat the nozzle earlier relative to its wipe you should be golden. It looks like they don't use Klipper, which means your slicer is probably controlling the order of things. Look at the print start gcode and have it heat the nozzle earlier. If you find whatever it has and copy/paste it here I, or someone else, will tell you what to move.
Happy printing!
- I don’t have a Bambu but what they also need to look at is retraction settings after purging the extra filament.
  Seems like it needs to retract a little more to lower the “pressure” of the melted filament in the nozzle.
  Best analogy is that this is like a giant glue gun. Squeeze really hard and fast and the glue isn’t going to stop when you let up in the trigger. Except, with a printer, you can have the extruder “retract” a little which does introduce a vacuum effect and slow/stop the oozing.
  Note: make small adjustments with a direct drive (which most of these printers are using these days) so you don’t pull molten plastic into the heatbreak and have to deal with clogs. However, if it’s oozing out you’re probably not even close to that being an issue.
  I use Klipper and OrcaSlicer but when I get a new type of Filament (ABS, PLA, TPU) I tune it including retractions. This way it does cleaner lines and is less likely to leave blogs, stringing. And tuning filament retractions here (or something specific to purges) should fix the issue.
  
  This is indeed the source of the extra filament. I'm just wary of suggesting you pull the filament too far up, which could take it out of the melt zone and cause a clog trying to get it back in.
  If OP isn't having stringing issues and wants to try this, they could add a smidge of retraction in the print end section of their slicer.

Maybe someone can answer this for me. Why do Bamboo Labs printers always have that stair step effect on the top-curves (top of the benchy)? The prints always look so good but my 10 year old Maker Select does better in that one spot.
- I would assume mostly from trying to speed up print time.
  The benchy is a 16 minute print and it lets the quality be good enough for that. If you are slicing the files yourself it can be a lot better especially if you are setting slightly lower layer heights and slower speeds.
  Not all prints have it.
  
  But every single one I've seen in person does, not just the benchys. Maybe it's something to do with default settings?

We got the carbon x 1 at work and I like it a lot. It's so easy to use.
- I’ve fucked with 3D printers since my first undergrad in 2012 and Bambu p1s blows my mind every print. Never to this day have had a print failure or problems with bed adhesion

I printed the poop chute too.. but after the first time the poop backed up on a long multicolor print, I replaced it with a simple shoebox which holds a lot more.

One of us! One of us! One of us!
I see you have chosen House Bambu, welcome! Be sure to print your AMS Pro upgrade, get yourself a bunch of Polymaker Dryboxes and a Dryer, and finally some Super Lube (and lithium grease).
- What am I supposed to lube / grease? Just the Z screws or other stuff too?
  
  Short answer: yes, please check the maintenance guides in the Bambu wiki and see the discussions on the Bambu forums.
  Long answer: I gave some context replying to OP here. I hope this helps.
- Oooooo what are some upgrades you'd recommend?
  
  Ok so first of all, a disclaimer:
  I'm not a 3D Printing veteran so please take my advice with a pinch of salt. My experience with 3D printers has been off and on over the last 10 years so whilst I've seen the hobby / industry change over time, I've only been hands on with a printer for a total of about 4 years, and only within the last 6 months have I had a printer of my own (Bambu P1S, and now an AMS for less than a month).
  Those 2 of those 4 years were at university with a haunted and spiteful Makerbot Replicator my engineering department threw out, a tiny shitty cube printer with a disposable stick-down bed which was all the student Makerspace I helped set up could afford. The other 2 years was the brand new university FabLAB where I got my hands on an Ultimaker 2, my first love.
  So whilst I have some knowledge I can share, it's not that deep and I don't want to pretend I know a lot about the specifics of Bambu printers when there's very likely to be much more experienced people in this community. I'm still getting to grips with my own printer.
  With that being said here's some generic upgrades to consider:
  AMS Silica Box Upgrade
  This is the one is great because the measly Silica bags that come with the AMS are OK but this will vastly improve keeping your filament dry which is good because:
  PLA when left out in average ambient air will absorb enough moisture to be unusable within 2 to 3 months and a lot sooner in a moist environment.
  Moist filament, even if usable, will cause print artifacts and increased risk of print failure.
  Some filaments like TPU absorb moisture a lot easier and therefore having a way to keep it dry passively in the AMS is good.
  For this print, pick up a Hydrometer and some Silica Beads with this size bottle just enough to fill the containers.

Hey see lots of people answering other questions but not the one you really want answered.
The basic nozzle wiper included sucks.
I have now tested probably about 4 different options and it's something that you will want to replace soon if you are doing consistent filament swaps in a print. The A1 mini scrubbers don't work quite as well as you would hope, mostly being that they hit the build plate back tab usually from where the nozzle wipes at and can grab filament and create a clog in the tube. I'm really liking the one I have on my printer though it needs to be printed with at least PETG realistically or ABS or ASA, but the nozzle wiper that uses a piece of tubing did the best job of cleaning the nozzle just also flung tiny little specs of plastic all over.

Buy more build plates also, especially textured as that will let you print everything basically and even TPU without a release agent on the build plate. I also really like the extra LED strip light replacement.
I'm currently in the finalizing my setup stages of an X1 and feel like I am finally in just printing away stage if you want to compare.

Have fun

How long did you have to wait for your printer? Mine is still stuck somewhere between Bambu and DPD.

I haven’t gotten one yet, but already research a lot in regards to buying a P1S myself.
During my research I found this today, which might resolve your issues: https://www.printables.com/model/613245-best-nozzle-wiper-abstreifer-bambu-p1x1
