A1 Y axis loud screeching?

Bambu Lab A1 Series
1

Has anybody else experienced their y axis on the A1 screeching loudly sometimes? It’s very loud; ear piercing loud. It’s not that way all the time; not sure what is causing it sometimes screech and not.

It wasn’t that way immediately; it happened after a few days of usage and has persisted since then (was hoping it would go away. Also tried restarts & firmware updates)

Getting ready to open a support ticket once the print finishes so I can get the logs.

I’m guessing I may need to try and lube/grease something? Though the wiki doesn’t have anything to say on this yet.

Maybe this can help you. The sound went away after my endeavour in the guts of the A1.

@Olias.95 thank you!

Also, they published the wiki for maintenance; including lube/grease stuff. I’ll try it out and report back if I have success: A1 Maintenance Guidelines | Bambu Lab Wiki

Happy to report that relubing y axis (followed video showing the wiki in my prior post) appears to have fixed the screeching noise; will report back here if the issue reappears
