Ender 3 V3 clicking as plate moves forward

I’ve been enjoying my Ender 3 V3 a lot for three months now. It’s working great, but I’ve noticed a small clicking sound when the plate moves forward past a certain spot. It’s a small click, and the prints turn out great. But obviously I want to get on this if something is going wrong. I have observed it very closely and looked everywhere I can without disassembly. It sounds like it’s coming from under the bed, but I can’t see anything under there, and nothing appears to be wrong with the belt or the belt pulleys. What could it be? Where should I look?

Thanks!

Hello !

Can you share a video with the sound ?
It would help locating the issue.
