Not very familiar with your setup but you say 21% speed. Are you cutting at 21% of the recommended speed?

Gotcha, I am used to speed being in inches per minute rather than a percentage.

In the image below showing the cut edge, is the torch cutting from left to right or right to left for this cut?

i wonder what hypertherm would say, an xpr should be able to make some pretty clean cuts on 2" material. Maybe a bad pierce wrecking the nozzle?

Well I am stumped. The bevel indicates possibly a cutting height too low, and the cut edge indicates possibly your traveling a bit fast. As cutnweld mentioned it could be as simple as a damaged nozzle.Worth looking at those possibilities.
