Calibration is proving to be a relatively slow process. As you can see from my prior post, my prints are drifting towards the back of the MakerBot. This appears to be due to either improper tension, the power being set too low for the Y stepper motor, and/or the Y axis rods not being smooth/oiled/straight enough. Given that the first few layers are spot on, I suspect it is a stepper board power issue. The Y axis motor is easily the first quietest of the three axes. As the X axis motor is the nosiest, I could probably dial it back without an effect on performance.

To do for tonight:

1. In the hopes of diminishing the Y axis drift problem
   1. Oil the Y (and X and Z) axis rods
   2. Check the Y (and X) axis slides
   3. Dial up the Y axis power by turning the potentiometer on the Y axis stepper board clockwise
2. In the hopes of diminishing operational noise
   1. Dial down the X axis motor slightly
   2. Dial down the Z axis motor slightly
