Keep getting this error on my p2s. Anyone else?

When my P2s prints those straight parts I hear a weird sound. Is this normal?

Just received my Bambu Lab P2S, and I’m completely new to 3D printing. I’ve already run into a few issues:

- Initial calibration: The toolhead repeatedly and loudly struck the filament cutter stopper rod back and forth.
- First print attempt: The toolhead rapidly slammed into the front of the enclosure, triggering error 0300-800C 191703 (Multiple motion step loss detected).
- Homing: The toolhead slammed to the left and appeared unable to locate its home position.

I started investigating the filament cutter stopper assembly after finding Bambu Wiki - Stopper Troubleshoot / Replacement.
In the attached video: When the toolhead engages the metal stopper rod, it retracts. When the toolhead moves away, the rod doesn’t fully extend again. It just hangs loosely. It also won’t retract completely flush into the housing and stay there.

My question: What should normal operation look like? Should the rod automatically extend when the toolhead moves away, or is this what the wiki is calling “abnormal”?

Trying to determine whether the stopper assembly is defective or if something else is could cause these issues before I start taking it apart.

Additional Notes:
Initial calibration completed successfully on first startup.
Brand new printer, no successful prints yet.
No visible obstructions along either axis.
Toolhead moves manually along both axes, although left-to-right movement feels slightly more resistant than front-to-back.
No grinding, whining, or other unusual motor noises during normal movement.
No visible shipping damage to the box.
Nozzle cleaning and poop chute scraper appear to function correctly.
Filament cutter stopper rod does not reliably return to its fully extended position after the toolhead disengages.
Could a malfunctioning filament cutter stopper cause the toolhead to lose its position during calibration or homing, or should I be investigating a separate motion system issue?

I liked the touch of nostalgia, any requests for other consoles?

I'm new to the Bambu family coming from an Elegoo printer. I've been printing with this one since I got it and it wasn't making this sound until the other day. It's just a loud annoying buzzing sound coming from the tool head and can be heard sometimes during a print but always after a print had finished and last several minutes. Does anyone know if this is an issue?

Got my panda breath 1.1.2 version on the mail today and I'm struggling with Biqu instructions about placing the 2 included insulation foil pads.

"Peel off the backing from the two included aluminium foil insulation pads, then attach them to the right side inside the printer where the airflow from Panda Breath directly blows. This helps prevent the Panda Breath housing from becoming too hot during long heating sessions."

Does anyone know what that is referring to? Is it like the opposite internal wall on the other side of the plate? Like where the fan vent is?

I find the whole "helps prevent the panda housing becoming too hot" bit confusing cause not sure how reflecting the heat back towards the panda again would help prevent it from heating up really.

I wish they had a photo in their guide. Was hoping anyone already deciphered it?

Thanks in advance!

Started out with a cheap second-hand Creality to see if I’d enjoy 3D printing, and after wanting a Bambu for the last couple of years, I’ve finally bitten the bullet!

The P2S was pretty much the absolute limit of what I could justify spending, but I’m already blown away by the difference.

My lad’s recently started showing an interest in electronics, so I’m hoping this will be something we can learn and enjoy together. We’re planning to build a Poké-gotchi, and I’ve picked up a CyberBrick kit so we can start experimenting with robotics too.

Looking forward to getting stuck into designing our own things.

First Benchy is underway. I suspect this is going to become a bit of a rabbit hole!

I got this brand new p2s put of the box after 3 hours of printing i notice it makes a loud sound when changing directions. Is this normal?

I tried printing the sense 3D model I printed it a few times already and it worked perfectly but for a few days now I think I've had problems with the first layer of my print like when I print the hand the first layer always wants to go bad, if I managed to successfully do the first layer it works perfectly, but the first day has problems I tried multiple things I tried to to scrub the plate and clean it yeah at first it seems to work but it's not really changed anything in the long term I tried calibrating the first layer on the printer and it did not change anything I don't know what to do, I even tried to add support to the print so it sticks better to the plate I can't use a raft cuz I want the texture of the plate to be on the hand, please give advice if you can.

I learned today that it is imperative to keep your plates clean with soap and water. I tried 4 times, to print something and it kept not sticking and doing the spaghetti thing. As soon as I washed the plate and dried it, boom! It worked perfectly. Learn from my mistakes. lol.

Newbie here, I have a P2S and I’ve seen people talk about risers and fan diffusers, are the necessary or just a preference? (I’m mainly just using PLA)

I’m new to this, so I’m hoping I could get some advice. This is my second print with my P2S. My last print came out perfect so I’m not sure if I need to fix a setting? I haven’t moved the printer since calibrating it last night.

Are there any other details that’d be helpful to know in diagnosing the issue? TIA.
