Realized that my x-axis was mirrored, but that was a quick fix by reversing both the X and Y motor connections along with the X and Y endstop connections. Got a few more test/calibration parts printed and pretty happy with how the early parts are coming along:
The Rostock MAX 250mm calibration cylinder scaled down 75% to a 187.5mm cylinder printed pretty well:

although there is some kind of repeating artifact along the sides, an upward curve seen in the photo below has a corresponding downward facing curve on the opposite side of the part (anyone seen this before? the side of the part has an ever so slight waviness to the surface as well corresponding to the pattern you see):

The pattern is due to positional accuracy limits, bound by your stepper motors' degrees per step.
