OS 업데이트

pi@NanoPi-NEO2-Black:~$ sudo apt update
pi@NanoPi-NEO2-Black:~$ sudo apt-get upgrade

파이썬 설치

OctoPrint 는 파이썬 환경에서 실행되므로 파이썬을 설치합니다.

pi@NanoPi-NEO2-Black:~$ sudo apt-get install python3-pip python3-dev python3-setuptools python3-venv git libyaml-dev build-essential

파이썬 버전 확인

pi@NanoPi-NEO2-Black:~$ python3 --version
Python 3.5.2

OctoPrint 설치

OctoPrint 작업 디렉토리 생성

pip 최신버전으로 업그레이드, OctoPrint 가상환경 생성

pi@NanoPi-NEO2-Black:~$ /home/pi/OctoPrint/bin/python3 -m pip install --upgrade pip

OctoPrint 설치

pi@NanoPi-NEO2-Black:~$ OctoPrint/bin/pip3 install OctoPrint

pi 계정 권한 변경

pi 계정에 터미널과 시리얼 접근권한을 추가해서 옥토프린트가 3D 프린터를 컨트롤할 수 있도록 합니다.

pi@raspberrypi:~$ sudo usermod -a -G tty pi 
pi@raspberrypi:~$ sudo usermod -a -G dialout pi
