X2D horrible top layers

X2D PLA Print flow rate isn't isn't fine - or some other issue?

Started to have artifacts at about 22 mm³/sec, dialed back to 20 and I’m still having problems. The squiggly lines have been mitigated by a generous lubing of the X and Y axis rods but the printer is clearly extruding plastic not the right way.
