One thing you may want to check. See if the material is bouncing. That thin, that much gas pressure, you are bound to have some movement.

I have seen material bouncing up and down relative to the nozzle causing the kerf to get wider and narrower with the distance from the focal point.

Just a though...

did you try moving the axes by hand to see if they're smooth? could be a bellows or something dragging

It turned out to be noise in the x axis, a perfect oscillation, probably the encoder.
