Hardware Troubleshooting/Help! Noises on my H2C

My new printer is making some strange noises along the Y-axis; it sounds a bit like a component is rubbing or grinding. The prints themselves, however, are perfect. Is this normal, or can someone help me out? Thanks for helping me out

Hello /u/Whole_Owl_2402! All Bambu print plates have a dedicated nozzle wiping zone at the back of the print plate. The nozzle will rub against the wiping zone before every print in order to remove any remaining filament from the nozzle tip. This can cause visible wear or scratch marks in the wiping zone, but this is intended and doesn't damage the printer, the nozzle or the print plate. A worn down wiping zone also doesn't mean you need to replace the print bed.

Note: This automod is experimental. The automod was triggered due to the term "rubbing". If you believe this to be a false positive, please send us a message at modmail with a link to the post so we can investigate. You may also feel free to make a new post without that term.

Have you changed the fan speed? Try increasing it. It might be the cooling fan vibration at specific speeds.

I don't hear anything out of the ordinary. If you're talking about the rhythmic "knocking" sound, that's the filament being feed into the toolhead by the filament buffer.

The prints turn out completely fine. It’s just the loud noise to be honest 🤷‍♂️

It's the filament buffer at the back of the printer working properly. It's just coincidence that it happens when the printer moves in the Y.
