The 3rd one with all the lines all over it looks like what my little X2 machine now produces.
I've rebuilt the whole thing to no avail.
I've narrowed mine down (I think) to the head gib slideways. Been like it since I badly crashed it and it looks like my head spread thus resulting in massive head vibrations. Looks, set and feels tight with no vibrations from table or column, just the head.

I'd like to say I never crashed my machine but that wouldn't be the truth. The mill is quiet and doesn't vibrate and straight line cuts are absolutely smooth. I'm thinking it's software related.
