Ready to print

It's a long story and a story for another time, perhaps. I finally got to the bottom of the problem with the x-axis drift. It was a firmware issue with how I structured the interrupt routine. Here you see a HDPE raft print of an x-axis raft after I figured out how to deal with that problem.

As you can see the x boundaries of the raft are both straight and parallel to each other. As well, you can see a y-axis raft.

Again, no problems. There are no fudges or correction factors in the code any longer. The firmware/hardware interface is sound.

We are ready to do some serious printing.
