Just hours to the semifinals deadline! I received the motors and adapted the calibration routines for this hardware version. As noted, the final hardware design will still change in some minor details. Nothing that affects finishing the software, though.

I made a video showing how the cameras are used in calibration; see the side bar. The mechanical switches are surprisingly accurate, but since we have cameras, we should use them! I'm happy with the accuracy, in the 0.02mm range.
