That's it Thanks!
I was using the GUI Auto-center parts preference. When I added --print-center 0,0 to the command line the g-code got very close. The coordinate components seem to have come in perfectly. The extrusion component seems to be off after the third decimal for some reason. But, I printed my test part and I can't discern a difference.
Please let me know if you can think of anything else I should check out. It would be really satisfying to get it to come in perfectly.
Thanks again.
