Exclamation traces and NFB connection

hello OS I remove that copper area and I was able to move it down away from U1 a few mm man if I knew that it need to be away from small signal at the beginning I will have it correctly placed you mention that reduce traces thickness mostly the signal ones right? the only traces that have signal are this pink one the other two are the supply voltage of the U1 servo, oh yeah question what does that NFB connection do if too close to signal traces is it magnetic distortion or some kind of induction distortion?

That is good. As I said , once it (nfb) goes through it's resistors , their signal
becomes one of the "small signal sources"
