Welcome to our club
This sounds like the normal first problems. as a full setup, you need to do a Calibration and then use Set Focus in that gear looking thing in the GFUI, It is still better also to be like that Sharpshooter that first shoots the side of the barn, and then paints a bullseye where it hit. If you cut your circle around your engrave it is much easier to make it accurate than if you try to engrave something already cut.
