Motors and hardware arrived today. Rather than wait for assembly, tonight’s session wrote the full 6-axis ESP32 stepper firmware, the ROS 2 bridge node, a tkinter GUI controller, and a complete motor test guide — so the moment the first print finishes, there’s a validated pipeline ready to wire into.
