Calibration

Here is a warning for those who are considering owning  a 3D printer.

This is what it takes to calibrate the dual extruder on the Lulzbot TAZ5. Each of the small cubes takes over an hour to make, so this was around 2 weeks worth of work.

Not to speak of just extruding 100 mm of filament over and over again to make sure the measured extrusion rate was just right.

And printing post-calibration prints to get everything working just right:

And some finer adjustments on a longer print.
