Unable to Cut clean lines

I apologize in advance because I am new to this. I feel like I have my machine dialed in pretty well. I am growing more and more irritated with the fact that I can’t get a clean cut. It seems like the machine moves off just a hair when cutting. Right when I think my project is cutting nice and clean the mill bit moves off course just slightly. I am noticing it when It is doing tabs as well. When the mill bit comes down it is off a little.

Any suggestions?

Thanks

Have you tried tightening your pots?
