More than 8"x8"?

[Agisis]

I believe the Rostock Max v2 is supposed to be limited to 8"x8". I've changed the tower cal routine to push it all the way out to the edges to really nail down the horizontal radius. I've successfully printed 8 1/2" x 9" pieces after having done this. It takes a work and I have to orient the piece just right, but it's been successfull to within a mm. Has anyone else had success doing this?
