OctoPrint installation on Orange PI PC – Autostart

2017-11-23 admin

After the installation of OctoPrint and CuraEngine in the previous article

we treat now the configuration of the 3d print server.

As first operation, we set up the automatic startup of OctoPrint.

Run the following commands

sudo cp /opt/octoprint/OctoPrint/scripts/octoprint.init /etc/init.d/octoprint
sudo chmod +x /etc/init.d/octoprint
sudo cp /opt/octoprint/OctoPrint/scripts/octoprint.default /etc/default/octoprint

sudo cp /opt/octoprint/OctoPrint/scripts/octoprint.init /etc/init.d/octoprint

sudo chmod +x /etc/init.d/octoprint

sudo cp /opt/octoprint/OctoPrint/scripts/octoprint.default /etc/default/octoprint

Edit the /etc/ defaults/octoprint file changing the pointing to the executable to start OctoPrint using vi

sudo vi /etc/default/octoprint

1	sudo vi /etc/default/octoprint

or nano

sudo nano /etc/default/octoprint

1	sudo nano /etc/default/octoprint

and edit the file from

taking into account also the different user being used.

Add the script to startup automatically OctoPrint

sudo update-rc.d octoprint defaults

1	sudo update-rc.d octoprint defaults

Start OctoPrint with the command

sudo systemctl start octoprint

1	sudo systemctl start octoprint

Check that OctoPrint is active on port 5000 of the Orange PI PC by accessing the address

http://IPORANGEPIPC:5000

1	http://IPORANGEPIPC:5000

Rebooting the Orange PI PC, the OctoPrint server now starts automatically.

In the next article, Linux will be configured to connect to OctoPrint on the Http standard port, i.e. on port 80

OctoPrint installation on Orange PI PC – Python package installation

2017-11-21 admin

This article describes how to enable the Orange PI PC board to work as 3d printers network server.

A software that provides this functionality is OctoPrint

OctoPrint

From the OctoPrint site we can download an image for Raspberry PI with the system already ready; in the case of the Orange PI PC we have to install and configure OctoPrint on a Linux image.

You can also use a Linux image available for Orange PI PC and run the steps related to OctoPrint package installation, but you have to check the prerequisites for Octoprint python package installation.

We instead built for this article an image using the Armban scripts.

As a first step, prepare the micro sd card with an Armbian image. In the specific case, we’ll use a Debian Jessie image created using the Armbian script, as indicated on the link

Armbian building

and described also in a previous article

Building Armbian image for Orange PI PC

We followed these steps to build the Armbian image on Ubuntu Xenial 16.04; from a Linux command shell

git clone https://github.com/armbian/build
cd build
./compile.sh

git clone https://github.com/armbian/build

cd build

./compile.sh

In the building options choose

We selected the default kernel configuration

Choose an Orange PI PC board

We used the mainline kernel

and Debian Jessie as distribution

We built an image with desktop envinronment

After this option, the script proceeds to the compilation. The generated image is Armbian_5.34_Orangepipc_Debian_jessie_next_4.13.12_desktop.img. This image can be downloaded from the link

Armbian image for Orange Pi PC

Start Armbian and create the user for the Jessie image; in this case we choose octoprint/password as user.

If necessary, reconfigure the keyboard with the command

sudo dpg-reconfigure keyboard-configuration

1 2	sudo dpg-reconfigure keyboard-configuration

and proceed to upgrade the system

sudo apt-get update
sudo apt-get upgrade

1 2	sudo apt-get update sudo apt-get upgrade

If the system needs to be configured via a wireless connection, the connection must be active at startup. For this purpose in our case we used the Wicd daemon

Wicd Debian

Remove the network-manager package

sudo apt-get remove network-manager

1	sudo apt-get remove network-manager

This command uninstalls network-manager and network-manager-gnome.

Check that the wireless interface is not present in

/etc/network/interfaces

cat /etc/network/interfaces

1	cat /etc/network/interfaces

Proceed to Wicd installation

sudo apt-get install wicd

1	sudo apt-get install wicd

Check that the octoprint user is present in the netdev group

cat /etc/group | grep netdev

1	cat /etc/group \| grep netdev

In our case it is already present, giving as a result

If not present, add it with the command

sudo adduser octoprint netdev
sudo /etc/init.d/dbus reload

1 2	sudo adduser octoprint netdev sudo /etc/init.d/dbus reload

Start wicd

sudo systemctl start wicd

1	sudo systemctl start wicd

Logon to the armbian graphic desktop and start the wireless configuration with the command

wicd-client -n

1	wicd-client -n

Configure and save the network connection from the graphical interface.

If you want the remote desktop follow the steps listed in the article

Remote desktop setup for Armbian on Orange PI PC

We can now install Octoprint. Follow the steps available at the link

OctoPrint installation on Linux

Install the prerequisites

sudo apt-get update
sudo apt-get install python-pip python-dev python-setuptools virtualenv python-virtualenv git libyaml-dev build-essential

1 2	sudo apt-get update sudo apt-get install python-pip python-dev python-setuptools virtualenv python-virtualenv git libyaml-dev build-essential

Create under /opt the octoprint folder and assign the ownership to octoprint

sudo mkdir /opt/octoprint
sudo chown octoprint:octoprint -R /opt/octoprint

sudo mkdir /opt/octoprint

sudo chown octoprint:octoprint -R /opt/octoprint

In a Linux shell command go to /opt/octoprint folder and download the software

cd /opt/octoprint
git clone https://github.com/foosel/OctoPrint.git

1 2	cd /opt/octoprint git clone https://github.com/foosel/OctoPrint.git

Run

cd OctoPrint
virtualenv venv
./venv/bin/pip install pip --upgrade
./venv/bin/python setup.py install

cd OctoPrint

virtualenv venv

./venv/bin/pip install pip --upgrade

./venv/bin/python setup.py install

Create the .octoprint folder

mkdir ~/.octoprint

1	mkdir ~/.octoprint

Add octoprint to the following groups to manage the 3d printer using the USB port

sudo usermod -a -G tty octoprint
sudo usermod -a -G dialout octoprint

1 2	sudo usermod -a -G tty octoprint sudo usermod -a -G dialout octoprint

Check the correct installation by running the command

/opt/octoprint/OctoPrint/venv/bin/octoprint

1	/opt/octoprint/OctoPrint/venv/bin/octoprint

The OctoPrint server can be reached on port 5000 at the IP address of Orange PI PC

http://ipaddress:5000

Install the Cura Engine at this point; place yourself in the octoprint user’s home and download the source package

cd
wget https://github.com/Ultimaker/CuraEngine/archive/15.04.6.tar.gz

1 2	cd wget https://github.com/Ultimaker/CuraEngine/archive/15.04.6.tar.gz

Unpack the package

tar -zxvf 15.04.6.tar.gz

1	tar -zxvf 15.04.6.tar.gz

Go into the unpacked folder

cd CuraEngine-15.04.6/

1	cd CuraEngine-15.04.6/

Run the compilation with the command

make

make

The compiled software is located under the build folder

Create the /opt /octoprint/cura folder and copy the CuraEngine file to this folder

mkdir /opt/octoprint/cura
cd ~/CuraEngine-15.04.6/build
cp CuraEngine /opt/octoprint/cura/

mkdir /opt/octoprint/cura

cd ~/CuraEngine-15.04.6/build

cp CuraEngine /opt/octoprint/cura/

The executable is now in the /opt/octoprint/cura folder and will be used later by OctoPrint.

In the next article we’ll treat how to configure OctoPrint’s automatic startup

Building Armbian image for Orange PI PC

2016-09-02 admin

We treat now the bulding of the image Armbian for Orange PI PC. From the developer’s github

Armbian Github

we find the steps to do the task.

From the Armbian site

Building Armbian

the supported building envinronment is Ubuntu. In our test we use Ubuntu 16.04.1 LTS x86-64

Ubuntu

and our Debian 8.5 envinroment used for the other tasks described on this site. With Ubuntu the compile.sh script installs all the required packages to build the image. On the Armbian web site we can find also various compilation options..

Using Debian 8.5 as host, we have to exectute some prerequisites tasks described below. In the case of issues execute the building on Ubuntu..

First we install the cross compilation envinronment in Debian

https://wiki.debian.org/CrossToolchains

We have to create the file crosstools.list in /etc/apt/sources.list.d

sudo vi /etc/apt/sources.list.d/crosstools.list

1	sudo vi /etc/apt/sources.list.d/crosstools.list

Edit this file and add the line

deb http://emdebian.org/tools/debian/ jessie main

1	deb http://emdebian.org/tools/debian/ jessie main

Save the file and add the repository key using curl. We install the curl package

sudo apt-get install curl

1	sudo apt-get install curl

and add the key

curl http://emdebian.org/tools/debian/emdebian-toolchain-archive.key | sudo apt-key add -

1	curl http://emdebian.org/tools/debian/emdebian-toolchain-archive.key \| sudo apt-key add -

Now we are ready to install the packages and architecture as listed below

sudo dpkg --add-architecture armhf
sudo apt-get update
sudo apt-get install autoconf
sudo apt-get install ccache
sudo apt-get install git
sudo apt-get install qemu
sudo apt-get install qemu-user-static
sudo apt-get install dchroot
sudo apt-get install debootstrap
sudo apt-get install apt-cacher-ng 
sudo apt-get install pigz
sudo apt-get install pv
sudo apt-get install mpv
sudo apt-get install  u-boot-tools
sudo apt-get install ntpdate
sudo apt-get install device-tree-compiler
sudo apt-get install pkg-config
sudo apt-get install libusb-1.0-0-dev
sudo apt-get install libusb-dev
sudo apt-get install gcc-4.9-multilib
sudo apt-get install crossbuild-essential-armhf

sudo dpkg --add-architecture armhf

sudo apt-get update

sudo apt-get install autoconf

sudo apt-get install ccache

sudo apt-get install git

sudo apt-get install qemu

sudo apt-get install qemu-user-static

sudo apt-get install dchroot

sudo apt-get install debootstrap

sudo apt-get install apt-cacher-ng

sudo apt-get install pigz

sudo apt-get install pv

sudo apt-get install mpv

sudo apt-get install u-boot-tools

sudo apt-get install ntpdate

sudo apt-get install device-tree-compiler

sudo apt-get install pkg-config

sudo apt-get install libusb-1.0-0-dev

sudo apt-get install libusb-dev

sudo apt-get install gcc-4.9-multilib

sudo apt-get install crossbuild-essential-armhf

At this point the procedure is the same on Ubuntu or Debian. We create a folder called armbian under orangepi folder in the home folder of the linux system; in our case the user is sviluppo

sviluppo@debian8:~/orangepi$ ls
openelec  sunxi
sviluppo@debian8:~/orangepi$ mkdir armbian

sviluppo@debian8:~/orangepi$ ls

openelec sunxi

sviluppo@debian8:~/orangepi$ mkdir armbian

We clone the repository with the following command in a shell command window in the armbian folder

git clone https://github.com/igorpecovnik/lib --depth 1
cp lib/compile.sh .

1 2	git clone https://github.com/igorpecovnik/lib --depth 1 cp lib/compile.sh .

To build the image execute

./compile.sh

1	./compile.sh

When requested enter the root password and for our image select the options described below.

Full OS image

Orangepipc board

default kernel

Debian stable image

Image with desktop envinronment

We find the image under the folder output/images ready to be transferred on a micro sd card as described in previous article

Configuration, Software

Remote desktop setup for Armbian on Orange PI PC

2016-08-11 admin

To enable the remote desktop for Armbian on Orange PI PC execute the logon to the system, for example using an ssh client

Delete, if installed, the packages

sudo apt-get purge vnc4server
sudo apt-get purge  tightvnc
sudo apt-get purge xrdp

sudo apt-get purge vnc4server

sudo apt-get purge tightvnc

sudo apt-get purge xrdp

Install the following packages

sudo apt-get install tightvncserver
sudo apt-get install xrdp

1 2	sudo apt-get install tightvncserver sudo apt-get install xrdp

Now we are able to login on Armbian using the remote desktop. Start the remote desktop client entering the Orange PI PC IP address

Execute the login with the user created at the first boot of Armbian, for example user1

We now have the access to the XFCE desktop remotely

Configuration, Software

Armbian Boot on Orange PI PC

2016-08-11 admin

After the creation of the micro sd card with the Armbian image for Orange PI PC

Armbian image on micro sd

we can boot the Orange PI PC with the card inserted in the card slot. At the boot the first operation is the partition increase on the card, then the system requires the root password change from the default, 1234, to a new password. The next operation is the creation of a normal Debian user, for example user1; we provide the main required informations like username, password and letting the default for the other fields. After these steps the system opens the XFCE graphical interface with the default resolution. To change the resolution execute the following command

sudo dh3disp

1	sudo dh3disp

It shows a list with all the available options; to enable a 1080p60 resolution execute

sudo h3disp -m 10

1	sudo h3disp -m 10

To change the locales configuration execute the following command choosing the language to use

sudo dpkg-reconfigure locales

1	sudo dpkg-reconfigure locales

while to modify the keyboard layout use the following command

sudo dpkg-reconfigure keyboard-configuration

1	sudo dpkg-reconfigure keyboard-configuration

SD card setup for Orange PI PC Armbian in Linux

2016-07-11 admin

As already described in the previous article

Openelec SD card setup

also for the Armbian distribution we have to prepare an sd micro card.It is advisable to use a micro SD class 10 to gain better performances. As first step we proceed to the Armbian image download from Armbian web site

Download Armbian Orange PI PC

We choose for example the Debian Jessie Desktop Image.

We install 7zip package. In Debian we can use the following command

sudo apt-get install p7zip

1	sudo apt-get install p7zip

After the file download wint 7z extension in a directory, we open a shell command window in this directory and unzip the content

p7zip -d imagename.7z

1	p7zip -d imagename.7z

We have among other files the one with .raw extension. Then we plug the micro sd card and check this device

sudo fdisk -l

1	sudo fdisk -l

In our case we have the following output

Disk /dev/sdb: 7,3 GiB, 7860125696 bytes, 15351808 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disklabel type: dos

Disk /dev/sdb: 7,3 GiB, 7860125696 bytes, 15351808 sectors

We check if this device is umounted

df

In the case we have the device in the output response, as in our case

we proceed to the unmount

umount /dev/sdb1
umount /dev/sdb2

1 2	umount /dev/sdb1 umount /dev/sdb2

WARNING: Be sure that the device is the micro sd card and not the internal disk. The next operation imply the complete rewriting of the device with the loss of all data on it.

We can now write the image into the micro sd card, using the correct device, that in our case is /dev/sdb

sudo dd if=./imagename.raw of=/dev/sdb bs=4M

1	sudo dd if=./imagename.raw of=/dev/sdb bs=4M

WARNING: This operation wipes all data on the micro sd card.

After a while we have the micro sd card ready to be used in the Orange PI PC board.
