Weird Noise

Bambu Lab P1 Series Troubleshooting
1

Hi all!

I’m fairly new to 3D printing and I’m facing this noise on my new P1S. I’m having trouble to understand the origin.
I’ve checked the belts at the back, and they run between the ball bearing without touching it. Kindly asking the community for some advices please :slight_smile:

I’m not sure what is causing it…but the whole things vibrates and it is quite noisy.

Detailed description of the problem
I have this weird sound going on while printing in PETG… it is less noticable when I’m printing something in PLA. (not sure if this is related somehow)

Printer model used
P1S
Slicer settings used
Draft settings - Sport mode
Type of filament used:
PETG

That’s horribly noisy. My PS1 was the same when I bought it but then I ran the “calibration” option in the menu. That made the printer much, much quieter. Except for one edge case - when printing large circles. That makes my printer sing when the print head is moving towards the front of the printer. At all other times, it is surprisingly quiet.

Thanks. In the end, I went through the entire maintenance process and performed calibration, then reduced the printing speed back to normal. The noise has decreased significantly. I also agree that it mostly occurs with rounded profiles.
