It's printing, or at least extruding plastic in recognizable shapes!
Printed a 10x10x5mm 1/2 cube & tried a 20x20x20mm cube.
There was a glitch that caused a Y axis shift about 4mm into the 20mm cube -- I'm not sure yet if it's hardware, firmware, or Gcode.
Next up -- Install limit switches. Since this requires partial disassembly, I might add some holes for wire management at the same time.
I was about to ask for Z axis limit suggestions, but remembered Ben Jackson's idea to put them at the top:
