Theta Printer - First Print

This is the first test print of the Theta Printer. A polar coordinate based 3D printer with the goal of being able to run 4 extruders simultaneously. Here we tested the operation of a single extruder arm. The object is a 20mm test cube. It is deformed because we haven’t yet modified the firmware to do the coordinate conversion.
