I have the same problem.
For me it helps to make vibration test settings or whatever it is called.
But those settings i can’t find in the Bambustidio on Windows.
Just in the Android app. So when printing via Windows i have this sound.
This doesn’t make sense. In either case the entire gcode file is transfered to the printer at the beginning of the print. In both cases the file was generated by Bambu Studio at some point.
On a related note, what infill pattern are you printing?

When printing via Android app the printer sounds different. So there must be a difference.
Mine was doing the exact same. Nothing to do with the carbon rods. The belt was running the bottom flange of the back right pulley. I loosened and manually tipped the tensioner so the belt is running in the middle of the pulley and the noise went completely away.
Ken Print has a video on this on Youtube on belt alignment.

Oh that could be the reason, but i had to verify tomorrow because im tooooo tired dealing with x1c today, i see people have exactly the same problem printing the bambu jet engine kit which is what i was doing, that cheers me up, anyway thanks Nathan for leaving this note
I solved this issue on mine and figured I’d post the solution here. First I cleaned the carbon rods, made no difference, second I cleaned and lubricated the metal y axis rods and it made no difference. Finally I took some sewing machibe lubricant Singer Acetite multi-uso and lubricated the pulleys. There are two idle pullies on the back accessible from the outside and 4 pulleys located on the ends of the x axis carbon rids. I dripped it onto the top and bottlm edges of the pulleys. I wiped any residue off of the belts then moved the x and y axis a small amount to help work the lubricant into the pulleys. I did this 3 or 4 times and each time the sound got quieter. It doesnt make that noise at all now.
I hope this helps anyone coming to this forumn post looking for help. Thanks OP for sharinf a good video of the noise. Im sure a lot of people’s machines will need this lubrication from time to time.

I’ll have to give this a try. My X1C is only a few weeks old and making this sound but mostly during the start of a print when it’s calibrating. It hasn’t affected the print quality yet but it’s definitely not right and I’m worried it’ll get damaged.
Sorry, but i think you have it wrong, there are no hard metal on the rods, it is not carbon dust your cleaning its graphite. The guides are graphite impregnated, this is how they are lubricated and why unfortunately will wear out. If they were a hard metal riding on the rods then yes a sealed bearing with thin grease and nylon seal would be good. But in a cost saving measure graphite impregnated sleaves is what they use.
Thats why ipa cleaning is best, but also as the graphite builds a thin film on the rods, overceaning can cause premature failure if the sleaves. Clean dry rods increases friction that alows the graphite to release, creating the proper lubrication.
Cheers

This is not your carbon rods. Change settings for scarf seam. You should also notice that it only happens on circular movements. The toolhead is pushing against the scarf seam as it goes around and fills the gap, solely depends on what you set the seam length, slope gap and start height.
Easy to test, disable scarf seam. I only get this noise printing PLA-Cf and have multiple X1C’s all doing the same.
Think mine has same ,just checked back right pulley and looks like what you described so will do
It tomorrow …fingers crossed .had A1 since day released and apart from the hearted saga had zero problems with it …had this X1 a month and it’s one problem after another !!
