Интегриране на РепРап в Blender

Това е първият ми опит за интегриране на РепРап в Blender.
За целта ще използваме последната версия на Blender [1], PySerial [2].

Необходим софтуер:

1. Blender 3.61
2. pyserial (инсталация за python3)

Хардуер:
1. RepRap Prusa с инсталиран Sprinter [3] firmware.

Последователност в Blender:

Примерна връзка на репрап в Блендер:

import sys
sys.path.append('/usr/local/lib/python3.2/dist-packages/') # path to pyserial for python 3.2

    """scan for available ports. return a list of device names."""
